title: Increased immunologic reactivity between human glomerular basement membrane and group A type 12 streptococcal cell membrane after carbohydrase treatment.
abstract: Anti-streptococcal cell membrane and anti-human glomerular antisera were evaluated on normal human kidney sections by an indirect immunofluorescent test both before and after absorptions with homologous and heterologous membrane preparations. The observed cross-reactions were potentiated by removal of carbohydrate units from both membrane-types by carbohydrase, a mixture of carbohydrate-cleaving enzymes.
