Abstract

An incompatibility in the reaction of human C2 with EAC14 consisting of guinea-pig C4 was demonstrated. Human C2 reacted poorly with EAC14 consisting of guinea-pig C4. The substitution of guinea-pig C4 on EAC14 with human C4 resulted in the fifteen- to twenty-fold increase of the haemolytic activity of C2 in whole human serum. It became more manifest in the titration of purified human C2. Purified human C2 showed about 100 times more activity with EAC14 consisting of human C4, although guinea-pig C2 reacted effectively with EAC14 carrying either guinea-pig or human C4. The unsuitability of the measurement of human C2 employing EAC14 prepared with guinea-pig C4 was shown.

摘要

已证实人C2与由豚鼠C4组成的EAC14反应存在不相容性。人C2与由豚鼠C4组成的EAC14反应较差。用人类C4替代EAC14上的豚鼠C4,可使全人血清中C2的溶血活性提高15至20倍。在纯化的人C2滴定中,这种情况更为明显。纯化的人C2与由人C4组成的EAC14反应时,活性高出约100倍,尽管豚鼠C2与携带豚鼠或人C4的EAC14反应有效。结果表明,使用由豚鼠C4制备的EAC14来检测人C2是不合适的。
