Abstract:
Objective:To prepare human angiopoietin like protein 2(ANGPTL2) monoclonal antibody.Methods:The purified recombinant human ANGPTL2 was used to immunize BALB/c mice.Then,the mouse spleen cells were isolated and fused with mouse myeloma cells.After selecting with HAT medium and analyzing with ELISA assay,the hybridoma cell clones stably secreting human ANGPTL2 antibody were screened out.The monoclonal antibody against humain ANGPTL2 was purified by ammonium sulfate precipitation method from the supernatant liquid of hybridoma cell culture.Western blotting,Cell immunostaining,and immunohistochemisty staining were used to characterize the antibody.Results:A strain of hybridoma cell clones stably secreting human ANGPTL2 antibody was screened out.The ANGPTL2 monoclonal antibody prepared was proven useful. Conclusion:A monoclonal antibody against human ANGPTL2 was successfully prepared,which provide a basis for basic study of ANGPLTL2.
