Invitrogen™ Novex™ Tricine SDS Sample Buffer (2X)

Novex Tricine SDS Sample Buffer (2X) is used to prepare protein samples for denaturing gel electrophoresis using tricine gels. Novex Tricine SDS Sample Buffer is specifically formulated for optimal electrophoresis of small proteins and peptides. The sample buffer is formulated with Coomassie Blue G and Phenol Red as tracking dyes instead of bromophenol blue. Coomassie Blue G gives a sharp dye front with Tricine SDS running buffers and migrates much closer to the moving ion front than bromophenol blue. Bromophenol blue runs more slowly than some peptides. This ensures that small peptides do not run off the gels.
