Bio-Rad Mini-PROTEAN Tris-Glycine extended (TGX) precast gels

Mini-PROTEAN Tris-Glycine extended (TGX) precast gels have been developed for protein electrophoresis using the standard Laemmli buffer system. The modification extends the gel shelf life to more than 12 months and can be run to completion in as little as 12 minutes.

The greater linearity of separation claimed with the gels delivers more accurate molecular weight estimation when compared with other precast gels. The proteins from the gel can be transferred onto a PVDF or nitrocellulose membrane in as little as 15 minutes. The gels are currently available in 7.5, 10, 12, 4-15 and 4-20% and in a formation called Any kD that offers optimal resolution of proteins in the 20-100 kD molecular weight range and are suitable for the second dimension of 2-D electrophoresis for rapid proteomic analysis.
