Technical Data
S5381-25
Spectrin, beta, Erythrocytic (Erythroid beta-Spectrin, Spectrin beta Chain Erythrocyte, SPTB, Beta-I Spectrin, SPTB1, EL3, HS2, HSPTB1, SPH2)
Description:
Erythroid spectrins, some other proteins of erythroid cytoskeleton, and the transmembrane protein band 3 are highly specific for 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.

Applications:
Suitable for use in Western Blot, Immunoprecipitation and Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
