[3H]L-glutamic acid binding to microfuge tubes and glass was investigated in four buffers. Background binding to these materials was negligible, but was increased by centrifugation or suction in Tris-HCl and Tris-citrate buffer. This binding was much less or eliminated when

Polyacrylamide gel electrophoresis (PAGE) is one of the most powerful tools used for protein analysis. We describe the use of Tris-acetate buffer and 3-15% polyacrylamide gradient gels to simultaneously separate proteins in the mass range of 10-500 kDa. We show

RNA-based applications requiring high-quality, non-degraded RNA are a foundational element of many research studies. As such, it is paramount that the integrity of experimental RNA is validated prior to cDNA synthesis or other downstream applications. In the absence of expensive

To separate and analyze giant and small proteins in the same electrophoresis gel, we have used a 3-15% polyacrylamide gradient gel containing 2.6% of the crosslinker bisacrylamide and 0.2 M of Tris-acetate buffer (pH 7.0). Samples were prepared in a
