Abstract:
Objective To construct antibody library in patient with pemphigus vulgaris using phage display antibody technique. MethodsTotal RNA was extracted from B cells of patients with pemphigus vulgaris(PV) using polymerase chain reaction,immunoglobulin VHand VL geneswere amplified by specific primer of HuVHBACK, HuJHFOR, HuVkBACK and HuJkFOR. The VH and VL genes were then cloned into a phage vector and expressed on the phage surface as a fusionprotein with product of gene Ⅲ.ResultsThe antibody phage library of single chain antibodies of patients with PV was constructed. ConclusionWe have obtained EC1-2 and EC3-4 purified protein of Dsg3 from constructed recombinant plasma in our laboratory which will facilitate the study on Dsg3 antibodies.
