特異性：Human glycophorin A Glycophorin A (GPA) is a 36 kDa sialoglycoprotein that is the most predominant sialoglycoprotein of the erythroid lineage. GPA is the major contributor to the net negative surface charge of the mature red blood cell (RBC) membrane thereby minimizing cell to cell interactions in circulation. The monoclonal antibody CMRF14 binds to glutaraldehyde fixed or neuraminidase treated erythrocytes but not to papain, trypsin or pronase treated erythrocytes.1, 2
