Rabbit anti-human GBM serum (A-H-GBMS) were obtained by rabbit's immunization with human GBM or rat GBM respectively. The content of anti-GBM antibodies in rabbit's sera was determined in IIT-GBM. The titer of the A-H-GBMS was 1/10 when determined in IIT-GBM performed in human GBM and only weakly positive in IIT-GBM performed in rat GBM. The titer of A-R-GBMS was 1/60 and 1/20 when determined respectively in rat GBM and in human GBM. All the reactions performed with sera absorbed with autologous GBM were negative; the absorption of sera with heterologous GBM reduced sera titer.\nIN CONCLUSION: a) rat and human GBM have common and different antigenic components; b) to detect human anti-GBM antibodies we must not employ rat GBM in IIT-GBM.","tracks":[]}
