Criterion Precast Gels

Criterion TGX Stain-Free precast gels are based on the long shelf life TGX formulation and have been developed for rapid fluorescent detection of proteins with the GelDoc Go and ChemiDoc MP imagers.

Criterion TGX precast gels are based on the long shelf life TGX formulation. The gels deliver superior resolution, fast run times, and greater transfer efficiencies.

Bio-Rad Tris-HCl gels are made without SDS. SDS is added to the sample and running buffer to create standard SDS denaturing electrophoresis conditions.

Tris-Tricine gels are ideal for separation of peptides and small proteins with a molecular weight <10,000. Superior resolution is achieved by slowing the migration rate of the peptide-SDS complexes.

Criterion XT precast gels are formulated at a near-neutral pH, significantly delaying acrylamide hydrolysis compared to traditional Laemmli systems. Their chemical composition allows maximum stability.

Isoelectric focusing (IEF) gels separate proteins based on their net charge rather than their molecular weight. IEF gels are cast with carrier ampholytes to create a pH gradient within the gel.

TBE gels are suitable for electrophoresis of nucleic acids from 50 to 2,000 base pairs; they are ideal for analysis of the purity of PCR products, standard dsDNA analysis, and RNase protection assays.

TBE-urea gels maintain denaturing conditions for analysis of single-stranded DNA and RNA. Nucleic acids between 60 and 200 bases are resolved as sharp, distinct bands.
