GenScript's Bis-Tris gels are high-performing polyacrylamide gels designed to separate a wide range of protein sizes by electrophoresis. The gels are cast in a neutral pH buffer that minimizes polyacrylamide hydrolysis and increases gel stability. Furthermore, the neutral pH which minimizes protein modification when compared to Tris-glycine gels.

• Large well volume
• High resoluton and reproducibility
• Long shelf life
• Cost effective
• Compatible cassette design

SurePAGE™ gels are premium, high resolution with enhance reproducibility gels, while the ExpressPlus are good quality and cost-effective gels.

Proteins are separated on SurePAGE using MOPS or MES running buffer. We recommend using MOPS buffer for protein sizes that are >30 kD and MES for proteins that are <30 kD.

We recommend using 4×LDS sample buffer (M00676) as the sample loading buffer.
