1.6 Important Notes
Use each Criterion precast gel as soon as possible after removing it from the storage pouch.
Improper storage of Criterion precast gels can produce numerous artifacts.
n
Store gels flat
n
Avoid prolonged storage at temperatures above those recommended
n
Do not freeze gels
n
If you suspect your gels have been stored improperly, discard them
Do not run more than one gel type in the same apparatus at the same time. Different gel percentages
and formulations have different conductivities and different run times.
Use unstained standards with Criterion TGX Stain-Free and Criterion Stain Free gels, as some
prestained standards are not detected by the Gel Doc
™
EZ imager. To monitor electrophoresis, use
10 µl of a 1:1 mixture of Precision Plus Protein
™
unstained and prestained standards.
