A nonurea electrophoretic gel system for resolution of polypeptides of Mr 2000 to Mr 200,000.


A sodium dodecyl sulfate-polyacrylamide gel electrophoresis system which resolves proteins and peptides from Mr 2000 to Mr 200,000 is described. Gradients of polyacrylamide, crosslinker, and glycerol buffered in Tris-phosphate (pH 6.8) are employed. Neither urea nor a stacking gel is required. This system has been used to separate molecules below Mr 3000… (More)
