The use of a protease for the extraction of antigens from chlamydia, and herpes gonococci.

摘要

An extraction method for lysing chlamydial, gonococcal or herpes organisms and extracting detectable antigen therefrom involves the use of a protease. In particular, the antigen can be effectively extracted from a biological specimen which contains whole blood or mucous using a protease. The extracted antigen can be effectively detected in an immunoassay involving antibodies directed to the antigen. The protease is novel to the process and is obtained from Bacillus subtilisin.
