Protein-blotting on Polybrene-coated glass-fiber sheets. A basis for acid hydrolysis and gas-phase sequencing of picomole quantities of protein previously separated on sodium dodecyl sulfate/polyacrylamide gel.

Abstract

A procedure has been developed which allows the immobilization on glass-fiber sheets coated with the polyquaternary amine, Polybrene, of proteins and protein fragments previously separated on sodium-dodecylsulfate-containing polyacrylamide gels. The transfer is carried out essentially as has been used for protein blotting on nitrocellulose membranes [Towbin… (More)
