title: Isolation of IgGT from hyperimmune horse anti-snake venom serum: its protective ability.
abstract: Hyperimmune horse anti-bothropic serum, used in serum therapy, was analyzed for its IgGT content and protective ability. IgGT was isolated through a combination of salt-mediated hydrophobic chromatography and protein A affinity chromatography. The chromatographic fractions obtained were analyzed with regard to their isotype content and protective ability. The results suggest that the protective ability of hyperimmune anti-venom serum is located mainly in the IgGT subclass.
