Biolegend, 340509, PE anti-human CD20 (cytoplasmic) Antibody, 25tests

CD20 is a 33-37 kD four transmembrane spanning protein also known as B1 and Bp35. CD20 is expressed on pre-B-cells, resting and activated B cells (not plasma cells), some follicular dendritic cells, and at low levels on a T cell subset. CD20 is heavily phosphorylated in activated B cells and malignant B cells. Homo-oligomeric complexes of CD20 are thought to form Ca 2+ conductive ion channels in the plasma membrane of B cells. The CD20 molecule is involved in B-cell activation and is associated with various Src family kinases (Lyn, Lck, Fyn), and exists in a complex with MHC class I and II, CD53, CD81, and CD82. The mAb 1412 recognizes the cytoplasmic domain of the CD20 molecule.

Q: What type of PE do you use in your conjugates?
A: We use R-PE in our conjugates.
Q: What is the difference between two anti human CD20 clones 2H7 and 1412?
A: For clone 1412: This clone specifically recognizes cytoplasmic domain of CD20 and thus can only be used for intracellular flow cytometry. In this instance you will need to include the fixation and permeabilization steps. Please follow the intracellular flow cytometry staining protocol.

For clone 2H7: This clone is ok for regular surface staining for CD20 and there is no need for any fixation and permeabilization steps.
