Quantitative immunoelectrophoretic assay for murine oncornavirus p30: noncovalent facilitation by sodium dodecyl sulfate

Abstract

Treatment of Rauscher murine leukemia virus lysates with the anionic detergent sodium dodecyl sulfate (SDS) at concentrations between 0.2 to 2.0% SDS per mg of viral protein greatly increased the anodal electrophoretic mobility of p30, the major internal polypeptide. SDS treatment did not reduce p30 antigenicity or cause nonspecific precipitation of normal serum proteins during subsequent immunoanalysis. The increased anodal electrophoretic mobility allowed assay of Rauscher murine leukemia virus p30 by Laurell rocket immunoelectrophoresis.
