3.2.2 Criterion Tris-HCl and Criterion Stain Free Gels
These Tris-HCl, Laemmli gels use discontinuous glycinate and chloride ion fronts to form moving
boundaries to stack and then separate denatured proteins by size. They are run using standard Laemmli
sample buffer and Tris/glycine/SDS running buffer.
