Use of a zwitterionic detergent for the restoration of the antibody binding capacity of immunoblotted Francisella tularensis lipopolysaccharide.

A method for the partial restoration of the antibody binding capacity of Francisella tularensis lipopolysaccharide ( LPS) following denaturation (dissociation) in boiling sodium dodecyl sulfate (SDS) is described. The method relies on the presence of a zwitterionic detergent in the matrix of an SDS-polyacrylamide gel and in the transfer buffer during an immunoblot. F. tularensis LPS, which had lost its earlier capacity to bind to a particular monoclonal antibody in the normal blot procedure, did bind following the addition of the zwitterionic detergent to the polyacrylamide gel and transfer buffer. A number of detergents were tested but most success in restoring antibody binding was achieved with Zwittergent 3-08. This simple modification to the immunoblot procedure proved helpful in identifying a monoclonal antibody specific to hot phenol-extracted F. tularensis LPS.[1]
