| Abstract: | An anti-placenta serum was absorbed by means of immunosorbents to remove antibodies against human serum proteins. The absorption met with some difficulties, because the anti-placenta serum contained antibodies against several human serum proteins. 12 different methods were compared for their suitability to adsorb these antibodies against human serum proteins. Most suitable is human serum cross-linked by glutardialdehyde. Good results were obtained too with human serum linked to Enzacryl, Polyaminostyrene or CNBr-activated Sephadex. |
