Procedure for immunologic determination of procollagen peptide (type III) and procollagen peptide col 1 (type III) together and a process for preparing anti-procollagen peptide col 1 (type III) serum

摘要

The antigens procollagen peptide (type (III) and procollagen peptide col 1 (type III) can be determined together immunologically by either PP(a) reacting a specified amount in each case of labeled procollagen peptide (type III) or procollagen peptide col 1 (type III) and a highly specific antiserum containing antibodies having affinity for both the antigens mentioned together with a sample having an unknown content of procollagen peptide (type III) and/or procollagen peptide col 1 (type III), separating off the antigen-antibody complex formed and measuring the amount of labeling in the complex and/or in the supernatant, orPP(b) bringing a specified amount of the highly specific antiserum to reaction with a sample having an unknown content of procollagen peptide (type III) and/or procollagen peptide col 1 (type III) , fixing the unreacted amount of the antibody to procollagen peptide (type III) or procollagen peptide col 1 (type III) bound to a support, and bringing to reaction with a labeled second antibody, and then determining the amount of bound or excess second antibody by measuring the labeling. An anti-procollagen peptide col 1 (type III) serum is preferred as the highly specific serum, and this is obtained by using procollagen peptide col 1 (type III) for immunizing experimental animals and obtaining their serum.
