Detection of lipopolysaccharides electroblotted onto membranes

Abstract

Specific detection of LPS on nylon, as described in a previously published method (Chen W.H., Balakonis P., Tsai C-M. Detection of lipopolysaccharides blotted on nylon membranes. J Endotoxin Res 1995; 2: 405-410), has been performed with Amersham's Hybond-N. The current reformulated Hybond-N nylon membrane of Amersham did not work with the method. Magna nylon (Micron Separations Inc.) has been found as a successful substitute with results similar to that of the old Hybond-N. Incorporation of 0.05% SDS in the 25 mM Tris-192 mM glycine transfer buffer resulted in specific detection for LPS and proteins with a high content of carbohydrate. Such a phenomenon seems unique to nylon but not for PVDF and nitrocellulose.
