1.2 Gel Formulations
Criterion precast gels are available in a range of formulations for virtually every electrophoresis
application (Table 1.1). All Criterion gels are composed of polyacrylamide with a bisacrylamide
crosslinker, and they are available in a selection of single percentages and gradients.
