CD20, a 33-36 kDa non-glycosylated type 1 transmembrane protein, is expressed by developing, resting and mature B cells, some follicular dendritic cells, and a small subset of mature T cells. B cell CD20 expression is lost upon differentiation into plasma cells. Functionally, CD20 activation contributes to B cell activation, proliferation, and differentiation.

iFluor™ fluorophores are optimized for strong fluorescence, high photostability and pH independence on proteins. They are avaialble to span the full UV-visible-IR spectrum. iFluor™647 is a great alternative to Alexa Fluor® 647, eFluor® 660. Do you need an antibody for an antigen you don't see on our website?
