A purified protein (CaDet) which in SDS Page gradient shows a molecular weight of about 25,000 Daltons has been eluted from antibody affinity columns with immobilized antibodies specifically directed against the protein C1 IAC described in U.S. Patent No. 4,132,769, by elution with a detergent. CaDet reacts with anti C1 IAC in immunoprecipitation tests and, when used for immunization, CaDet gives increased titers of anti C1 IAC. |
