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 on activated B cells and malignant B cells. Homo-oligomeric complexes of CD20 are thought to form Ca2+ 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). It exists in a complex with MHC class I and II, CD53, CD81, and CD82.Product Details

- Recommended Usage
- This product is suitable for use with the Maxpar® Metal Labeling Kits. The product is formulated so that the buffer exchange step is not required (steps 7, 8, 9, and 10 in the Maxpar® antibody labeling protocol). Just add 100 µl of this antibody to 100 µl of 4 mM TCEP-R in a 50 kDa filter, as described in step 11, and continue with the protocol.
- Application Notes
The epitope recognized by clone 2H7 has been mapped to the sequence YNCEPANPSEKNSPST which lies in the large extracellular loop of human CD20. Additional reported applications (for the relevant formats) include: immunoprecipitation4 and immunohistochemical staining of acetone-fixed frozen sections5.

- Can I obtain CyTOF data related to your Maxpar® Ready antibody clones?
We do not test our antibodies by mass cytometry or on a CyTOF machine in-house. The data displayed on our website is provided by Fluidigm®. Please contact Fluidigm® directly for additional data and further details.
- Can I use Maxpar® Ready format clones for flow cytometry staining?
We have not tested the Maxpar® Ready antibodies formulated in solution containing EDTA for flow cytometry staining. While it is likely that this will work in majority of the situations, it is best to use the non-EDTA formulated version of the same clone for flow cytometry testing. The presence of EDTA in some situations might negatively affect staining.
- I am having difficulty observing a signal after conjugating a metal tag to your Maxpar® antibody. Please help troubleshoot.
We only supply the antibody and not test that in house. Please contact Fluidigm® directly for troubleshooting advice: http://techsupport.fluidigm.com/
- Is there a difference between buffer formulations related to Maxpar® Ready and purified format antibodies?
The Maxpar® Ready format antibody clones are formulated in Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and EDTA. The regular purified format clones are formulated in solution that does not contain any EDTA. Both formulations are however without any extra carrier proteins.
- What is the difference between two anti human CD20 clones 2H7 and 1412?
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.
