Abstract:
Objective:To generate rabbit-anti B16 melanocyte polyclonal antibodies and study the effect on melanocyte proliferation.Methods:Rabbits was immunized with B16 melanocytes to produce rabbit anti-B16 melanocyte polyclonal antibody(pAb).The titer of the antiserum was then detected using the tube agglutination assay;The antiserum was purified through the G protein affinity chromatograph,and the molecular weight of the purified Ab was identifed through SDS-PAGE.The effect of purified IgG on B16 melanocytes proliferation was detected using MTT assay.Results:The titer of the antiserum reaches 1∶1 280;SDS-PAGE shows that the heavy chain molecular weight of the purified IgG is 66.2 kD;MTT assay shows that the IgG fraction inhibited the proliferation of B16 melanocytes with signifancent difference when compared to none IgG or no purified antiserum.Conclusion:The rabbit anti-B16 melanocytes pAb with high titer is preparated successfully.The purified IgG can inhibit proliferation of B16 melanocytes.It could be useful in studying the effect of this antibody on melanocyte growth and pigment metabolism,it also be useful in studying the pathogenesis of vitiligo.
