ABSTRACT
Objective To prepare and identify rabbit anti-cyclin dependent kinase 6 (CDK6) antibody. Methods The recombinant pET21a (+)/CDK6 was successfully constructed, then the recombinant plasmid was transformed into E.coli BL21 (DE3) competent cells and was induced by isopropyl-β-D-thiogalactopyranoside (IPTG) for protein expression, which was detected by SDS-PAGE and Western blot analysis. The expressed protein was purified by nickel-chelating nitrilotriacetic acid (Ni-NTA) agarose and then analyzed by SDS-PAGE. Japanese white rabbits were immunized with purified CDK6 protein for many times every two weeks. The blood was collected at 0, 2, 4 and 6 weeks after immunization, and serum was separated from blood. The titer was detected by indirect ELISA. Western blot analysis, immunofluorescence assay and immunohistochemistry were employed to determine the specificity. Results High purity CDK6 protein and high specificity of rabbit anti-CDK6 antibody were successfully prepared. The titer of CDK6 rabbit serum antibody reached 130 000 after immunization, which could specifically recognize the CDK6 protein expressed in cervical cancer cell line and cervical cancer tissues. Conclusion The high titer and specificity of rabbit anti-CDK6 antibody is successfully prepared.
