Embodiment 1
[0114] Embodiment 1: the preparation of PCT antigen
[0115] (1) Take 1 mg PCT full-length antigen;
[0116] (2) Prepare 2ml of enzymatic solution: Prohormone Convertase (PC), Carboxypeptidase (CP), Aminopeptidase (AP), Pepeitdyl Glycine Amidating Monooxygenase (Pepeitdyl Glycine Amidating Monooxygenase) -oxygenase, PAM) each 30IU / g dissolved in 20mM Tris, 500mM NaCl, pH7.4 buffer.
[0117] (3) Add enzymatic hydrolysis solution, enzymatic hydrolysis in water bath at 37°C for 2 hours;
[0118] (4) Separately couple three monoclonal antibodies against N-terminal (N-proCT), calcitonin (CT) and calcitonin (Katacalcin, KAT) antigens to the chromatographic column, and enzymatically digest The solution was sequentially filtered for affinity purification to obtain three antigens: N-terminal (N-proCT), calcitonin (CT) and anti-procalcitonin (Katacalcin, KAT). The specific steps are as follows:
[0119] a The above antibodies were bound to protein A microbeads respectively. 2 mg of ...
Embodiment 2
[0130] Example 2, detection of PCT epitope peptides
[0131] Specific identification of immune response to PCT antigen polypeptide by Western blot: take the final purified procalcitonin polypeptide for 15% SDS-PAGE identification, and use the anti-PCT monoclonal antibody produced by Abcam to perform western blot analysis on it, using Millipore Immobilon The Western Chemiluminescent HRP Subscrate system developed the color, and the results showed that a clear band can be seen where the anti-PCT monoclonal antibody binds to the PCT protein.
Embodiment 3
[0132] Embodiment 3, the preparation of PCT epitope peptide antigen
[0133] The related antigen obtained in Example 1 is coupled with related macromolecular substances to improve its immunogenicity: the PCT N-terminal (N-proCT), calcitonin (Calcitonin, CT) and calcitonin (Katacalcin, KAT) is coupled with latex microspheres, KLH, BSA, GST, etc., and part of the coupling needs to add a cross-linking agent to promote the improvement of its cross-linking rate. The obtained antigenic polypeptide fragments can be used to immunize animals.
