more advantageous. It is specially designed for high resolution
protein separations and boasts a list of impressive features.
Compact and convenient it has its own built-in versatile power
pack which can be used for wider laboratory applications when
not being used for electrophoresis. The sideways de-staining
technique employed by this equipment means absolute simplicity
and maximum speed. And to prevent denaturing of the proteins
and again speed up separating time the Quickfrt PACE, incorporates a special cooling coil.

ELECTROPHORESIS OVER OTHER ELECTROPHORET1C TECHNIQUES PLUS ITS OWN VERY
SPECIAL ADVANTAGES I
Polyacrytamjda gel electrophoresis is a technique which afford*
the user many advantages — it is more sensitive than routine
starch g«< techniques, more reproducible than either paper or
cellulose acetate and increases speed of total analysis time by as
much as 400 to 600 per cent (From 8-12 hours to1J-2 hours).
With the Quickfit P A C E , unit this technique becomes even
