Abstract
Finding a protein of a minute amount present on a cell membrane to provide a method for producing an antibody against the protein. Producing an antibody using a protein identified by an identification method including: a labeling step of using a labeling agent comprising at least one selected from bis-iminobiotin compounds and bis-biotin compounds to obtain cells having a labeled protein; a degradation step of preparing a degradation product for an immobilization treatment, the degradation product containing the labeled protein; an immobilization step of immobilizing the labeled protein contained in the degradation product for an immobilization treatment on a stationary phase via a streptavidin mutant; a cleavage step of releasing an analysis sample from the stationary phase on which the labeled protein is immobilized; and an analysis step of analyzing the analysis sample to identify the labeled protein.
