Criterion™ Tris-HCl Precast Gels
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.

Criterion Tris-HCL Precast Gels are ideal for vertical midi gel electrophoresis. They provide Laemmli separation patterns using a standard Tris-glycine running buffer system. Criterion gels are compatible with the Criterion cell (1–2 gels) and the Criterion™ Dodeca™ cell (1–12 gels).
Features and Benefits
- Reproducible, high-resolution results
- Fast setup, loading, and run times
- Numbered, marked well outlines on the cassette ease sample loading and identification
- Made without SDS, they can also be used with nondenaturing sample and running buffers (native PAGE conditions) to separate proteins by mass-to-charge ratio
- Use same buffers and band patterns as Laemmli systems
- Robust system allows separation of complex samples
- Run 2-D gels in less than a day
Applications and Uses
- Polyacrylamide gel electrophoresis (PAGE or SDS-PAGE)
- 2-D gel electrophoresis
- Accurate molecular weight estimation
