A plant dye from Lawsonia inermis for protein staining after polyacrylamide gel electrophoresis.
Electrophoresis. 1990 Apr; 11(4):343-4.E

Abstract

A reddish-brown dye was isolated from the leaves of Lawsonia inermis by extraction with calcium hydroxide (pH 11-12). A 3.6% crude extract in ethanol/water, 1:1 v/v, was used for direct staining, without fixation, of bovine serum albumin, casein and human serum proteins, following polyacrylamide gel electrophoresis in cylindrical gels. After staining for 30 min the gels were destained for 1/2-2 h with 7% acetic acid at 60 degrees C. Protein staining with Amido Black 10B and Coomassie Brilliant Blue R-250, according to standard protocols, required destaining for 24 h and more to obtain a comparably cleared background. Staining with the plant dye and Coomassie Brilliant Blue had a similar overall staining sensitivity but some minor components of human serum showed different staining characteristics with each of the two dyes. Staining with the plant dye excels over standard staining by speed and simplicity.
