Clone Number: 93-1B3
Immunogen: stimulated human leucocytes
Concentration: 100 ug/ml
Storage buffer: PBS with 0.02% sodium azide
Additional info: 93-1B3 binds with CD20 which is a 30/33 kDa non-glycosylated transmembrane phosphoprotein with three extensive hydrophobic regions. CD20 is involved in regulation of Bcell activation. It is expressed on the surface of all B-cells beginning at the pro-B phase (CD45R+, CD117+) and progressively increasing in concentration until maturity. Plasma cells are negative. CD20 is retained on many B-cell malignancies. CD20 positive cells are also sometimes found in cases of Hodgkin’s disease, myeloma, and thymoma. 93-1B3 has been clustered at the IIIrd and Vth HLDA Workshops.
