title: Streptococcal protein G: a sensitive tool for detection of antibodies to human immunodeficiency virus proteins in Western blot analysis.
abstract: Protein G is a cell wall protein of group C and G streptococci which binds human IgG antibodies of all four subclasses with high affinity. This property of the molecule was utilized to develop a sensitive Western blot assay to detect antibodies against HIV proteins in patient sera.
