Method
In this test, 10 μL of test solution was dropped on a swab for each model, and the luminescence
intensity was measured according to the procedure of using the equipment described in each
instruction manual. The temperature in the laboratory was set to 22°C, and each reagent had been
placed at room temperature for 1 hour before the test started.
(1) Measurement test of ATP solution
ATP (Adenosine-5'-triphosphate, Oriental Yeast Co., Ltd.) was dissolved into ultrapure water, and
serial dilution was performed to prepare 10 -11 mol/L, 10 -10 mol/L, 10 -9 mol/L, 10 -8 mol/L, 10 -7 mol/L,
10
-6
mol/L, 10
-5
mol/L, and 10
-4
mol/L solutions as the test solutions. 10 μL of test solution was
dropped on a swab for each model, and each luminescence intensity was measured. Each test
solution was measured 10 times.
A standard curve is created from the obtained measured values, and the repeatability of the
measured values was expressed as a coefficient of variation (CV %=100 x SD / Mean). Also, the limit
of detection (RLU) of each model was calculated from the blank value (LOD=Mean+3 x SD). In
addition, the calculated value was divided by the slope of the standard curve , and the limit of
detection (mol) was calculated by (LOD=(Mean+3 x SD) / Slope of curve).
(2) Luminescence persistence test
The luminescence intensity was measured every time elapsed using the 10
-7
mol/L ATP solution to
be used for the test (1) to test the luminescence persistence. The swab on which 10 μL of test solution
was dropped was set for each of 4 models, Lumitester PD-20, UNG3, SystemSure Pro, and Ensure,
and the measurement button was pressed at the intervals of 20 seconds by measuring the time with
a stop watch after the test started. The measurement was repeated by pressing the measurement
button at 0 seconds, 20 seconds, 40 seconds, 60 seconds, 80 seconds, 100 seconds, and 120 seconds.
The measurement was conducted 6 times for each model.
As for AccuPoint, the swab on which 10 μL of test solution was dropped was set, and the
luminescence intensity was repetitively measured by measuring time with a stop watch after the
test started and by opening/closing the lid for the swab insertion port every 40 seconds. The
measurement was performed at 0 seconds, 40 seconds, 80 seconds, and 120 seconds 6 times each.
The average value for each time was calculated, and the percentage of change from the start of the
measurement (0 seconds) was found.
(3) Measurement test of AMP solution
AMP-Na (Adenosine-5'-monophosphate (disodium salt), Oriental Yeast Co., Ltd.) was dissolved into
ultrapure water, and serial dilution was performed to prepare 10 -7 mol/L solution as the test solution.
10 μL of test solution was dropped on a swab for each model, and the luminescence intensity of the
swab was measured. Measurement was done 6 times for each model.

(4) Measurement of food suspensions
The following suspensions of 5 foods were measured.
Ground pork (raw)
Shrimp (boiled)
Beer
Orange juice (100% pure fruit juice)
Milk (pasteurized)
10 g of ground pork or 10 g of shrimp was put into a stomacher bag together with 90 mL of ultrapure
water and they were subjected to stomacher treatment for 2 minutes. The solution obtained was
used as the stock solution and stored with it cooled with ice until the start of the test. Beer, orange
juice, and milk were used as the stock solutions with them undiluted. The stock solution of each food
was diluted serially with ultrapure water at ratios of 1:1, 1:10, 1:100, 1:1000, and 1:10000 to obtain
the test solutions. 10 μL of test solution was dropped on a swab for each model, and the luminescence
intensity of the swab was measured. Measurement was performed 6 times for each model.
A standard curve was created from the obtained measured values, and the limit of detection of each
model was calculated from the blank value (LOD=Mean+3 x SD). When 0 was contained in a blank
value, the mean value of the dilution level for which all measurement values were 1 RLU or greater
was found, and that mean value was taken to be the detection limit.
(5) Measurement of microbial suspension
Measurement was performed for 3 kinds of microbial suspensions.
Escherichia coli IFO3972
Staphylococcu aureus IFO12732
Saccharomyces cerevisiae NBRC10217
E. coli and S. aureus were inoculated in 10 mL-heart infusion broths (Eiken Chemical Co., Ltd.),
respectively, and were subjected to shake incubation at 37°C over night. 10 mL of the culture
solutions were centrifuged at 4500 rpm for 10 minutes. The supernatant liquids were discarded and
the residues were suspended in 10 mL of sterile physiological saline solutions. After that, they were
centrifuged at 4500 rpm for 10 minutes again, and the supernatant liquids were discarded and the
residues were suspended in the sterile physiological saline solutions to obtain the stock solutions. S.
cerevisiae was streak-smeared on potato dextrose agar madia (Nissui Pharmaceutical Co., Ltd.), and
cultivated at 30°C for 2 days. The cultivated colonies of S. cerevisiae were suspended in sterile
physiological saline solution and centrifuged at 4500 rpm for 10 minutes. After the supernatant
liquid was discarded and the residue was suspended in sterile physiological saline solution, it was
centrifuged at 4500 rpm for 10 minutes and suspended in sterile physiological saline solutions.
Bacterial numbers were adjusted using a counting chamber to obtain the testing stock solutions. The
FCG Research Institute,Inc.

concentrations of E. coli, S. aureus, and S. cerevisiae of the testing stock solutions were 3.2 x 10
CFU/mL, 4.1 x 10
9
CFU/mL, and 2.5 x 10
8
9
CFU/mL, respectively. The respective stock solutions
were serially diluted with sterile physiological saline solution to obtain 10 9 CFU/mL, 10 8 CFU/mL,
10 7 CFU/mL, 10 6 CFU/mL, 10 5 CFU/mL, and 10 4 CFU/mL solutions of E. coli or S. aureus, or 10 8
CFU/mL, 10 7 CFU/mL, 10 6 CFU/mL, 10 5 CFU/mL, 10 4 CFU/mL, and 10 3 CFU/mL solutions of S.
cerevisiae as the test solutions. 10 μL of test solution was dropped on a swab for each model, and the
luminescence intensity was measured. The frequency of the measurement for a test solution was 6
times.
A standard curve was calculated from the obtained measured values, and the limit of detection of
each model was calculated from the blank value (LOD=Mean+3 x SD). When 0 was contained in a
blank value, the mean value of the dilution level for which all measurement values were 1 RLU or
greater was found, and that mean value was taken to be the detection limit.
Results of the measurements
(1) The measurement test of ATP solution
Table 2 shows the summary of the measured values (RLU) of ATP measured for each model, and Fig.
2 shows the standard curve. In addition, Fig. 3 shows the repeatability in the measurement of ATP
10
-12
mol/assay. In the case of SuperSnap, the concentration of ATP of 10 -12 mol/assay was near the
detection limit and the variation in numerical values was small, so the repeatability was evaluated
at ATP 10 -13 mol/assay.
For the lower limit of detection, the sensitivity of SuperSnap was good, and detection up to 10-15mol
was possible. LuciPac Pen, CleanTrace and AccuPoint have detected to 10-14 mol. LuciPac Pen and
CleanTrace were linear to 10-10 mol, and have detected high concentration compared with other
models. LuciPac Pen had good repeatability of ATP measured values (CV value = 2.9%, Fig. 3), and
AccuPoint showed substantial variation in numeric values.

(2) Luminescence persistence test
Table 3 shows the summary of the measured values (RLU) from the result of measuring ATP 10
-12
mol/assay every time elapsed, and Fig. 4 shows the progress of increase and decrease.
LuciPac Pen had the best persistence of luminescence intensity. Clean Trace had the second highest
persistence, but there was the trend toward slight increase in the luminescence as the time passed.
In the case of SystemSure, the luminescence increased after 20 seconds, and decreased after that. In
the case of other 2 models, substantial decrease in luminescence occurred as the time passed.

(4) Measurement of food suspensions
Table 5 and Fig. 6 show the measured values (RLU) of ground pork measured for each model. In the
similar way, Table 6 and Fig. 7 show the measured values of shrimp suspensions, and Table 7 and
Fig. 8 show the measured values of beer. Table 8 and Fig. 9 show the measured values of orange juice,
and Table 9 and Fig. 10 show the measured values of milk.
Although LuciPac Pen and CleanTrace have detected up to 1:100 dilution level by measurement of
ground pork, as compared with CleanTrace, LuciPac Pen had linearity at a 1:100 dilution level and
was especially good. Especially the power of test of LuciPac Pen was good for measurement of shrimp,
and was not less than the limit of detection at a 1:10000 dilution level. The measured value of beer
had a low tendency compared with other food. Although the LuciPac pen could detect at a 1:100
dilution level in measurement of beer, CleanTrace, UltraSnap and AccuPoint were hardly able to
detect. In the measurement of orange juice, the sensitivity of each model was high, and each detected
to a 1:10000 dilution level. In the measurement of milk, SuperSnap could detect up to a 1:1000
dilution level, and CleanTrace and UltraSnap could detect up to a 1:100 dilution level. The 1:100
dilution of the milk of LuciPac Pen was almost the same as the limit of detection.

In the measurement of E. coli and S. aureus, LuciPac Pen, CleanTrace and SuperSnap could detect
103 CFU. In measurement of S. cerevisiae, LuciPac Pen and SuperSnap showed a high power of test,
and exceeded the detection limit in 101 CFU of measurement. The coefficient of variation (CV value)
of the measured value in 3 strains of LuciPac Pen was low. Also, LuciPac Pen had good repeatability
of 3 strains of measured values.

Summary of the results
(1) The measurement test of ATP solution
In the case of measurement of ATP, detection sensitivity of SuperSnap was good, and could detect
10-15mol. LuciPac Pen, CleanTrace and AccuPoint were able to detect up to 10-14 mol. LuciPac Pen
and CleanTrace were linear to 10-10 mol, and have detected high concentration compared with other
models. LuciPac Pen had good repeatability of ATP measured values, and AccuPoint showed
substantial variation in numeric values.
(2) Luminescence persistence test
LuciPac Pen had the best persistence of luminescence intensity. Clean Trace had the second highest
persistence, but there was the trend toward slight increase in the luminescence as the time passed.
In the case of SystemSure, the luminescence increased after 20 seconds, and decreased after that. In
the case of other 2 models, substantial decrease in luminescence occurred as the time passed.
(3) Measurement test of AMP solution
In the measurement of AMP, only LuciPac Pen could detect it well, while other models could not
detect it.
(4) Measurement of food suspensions
In the measurement of food suspension, LuciPac Pen had basically high detection ability, especially
in the case of ground pork, shrimp, and beer, good results were obtained. In the case of orange juice,
the sensitivity of each model was high. In measurement of milk, the power of test of SuperSnap was
good, and the power of test of CleanTrace and UltraSnap were good in that order.
(5) Measurement of microbial suspensions
In measurement of E.coli and S. aureus, LuciPac Pen, CleanTrace and SuperSnap could detect 103
CFU. In measurement of S. cerevisiae, LuciPac Pen and SuperSnap showed high power of test, and
exceeded the detection limit in 101 CFU of measurement. Also, LuciPac Pen had good repeatability of
3 strains of measured values.
