Target/Specificity Mouse anti-Human CD21 antibody, clone LB21 recognizes the human Complement receptor type 2, also known as CD21 or the Epstein-Barr virus receptor. CD21 is a ~14 kDa cell surface glycoprotein expressed by mature B cells and by follicular dendritic cells. The molecule acts as a receptor for complement components C3d, C3dg and iC3b, as well as for Epstein Barr Virus. It forms part of a large signal transduction complex in association with CD19.
Preservative & Stabilisers 0.09% Sodium Azide
Storage Store at +4℃ or at -20 ℃.
PrecautionsAnti-Human CD21 Antibody, clone LB21 is for research use only and not for use in diagnostic or therapeutic procedures.
