Recombinatino polypeptide or chemically synthesized polypeptide antigen is used to immunize the mammal to obtain polyclonal antibody and the nonconservative amion acid sequence of the antiboby to N-terminal with recognition site qBrn-2 of development regulatory protein qBrn-2. The antibody does not recognize other POU structure domain protein, and recognizes specifically qunique protein in Western imprinting experiment. The qBrn-2 expression mode obtained immunohistochemistry process is identical with the resulted height of in-situ molecular hydridization.
