Mouse monoclonal antibody raised against native SPTB.
Native purified human SPTB.
This antibody is specific to the 220kD human erythroid beta-spectrin. The protein is also present in the membranes of human skeletal muscle cells. Erythroid spectrins, some other proteins of erythroid cytoskeleton, and the transmembrane protein band 3 are highly specific to erythrocytes and their progenitors. They are more reliable markers for erythroid differentiation than Glycophorin A, the commonly used marker for erythroid differentiation, because Glycophorin A is expressed also in many cell lines otherwise exhibiting mainly megakaryotic charasteristics. Monoclonal antibody to erythroid beta-spectrin is derived from the hybridoma produced by fusion between myeloma cells and Balb/c spleen cells.
