Abstract:
Objective To express major outer membrane protein (MOMP) of Chlamydia trachomatis E and to prepare rabbit polyclonal antibody. Methods The recombinant plasmid MOMP/ pGEX6p-l prepared by our lab was introduced into E. coli. The protein was expressed and purified by gel recycling, then was injected into New Zealand rabbits to produce polyclonal antibodies. Enzyme linked immunosorbent assay (ELISA) was used to detect the titer of antibody. The antibody specificity was identified by Western blot and immunofluorescence. Results The fusion recombinant protein glutathione S-transferase (GST)-MOMP was successfully expressed in E. coli. The titer of antibody recombinant protein detected by Western blot and to the endogenous MOMP of Chlamydia trachomatis in vitro detected by immunofluorescence. Conclusions The recombinant MOMP is successfully expressed and the MOMP antibody with high titer and high specificity is obtained. which will be helpful for Chlamydia trachomatis detection and related clinical research.
