    Human frozen tonsil section was fixed with 4% paraformaldehyde (PFA) for ten minutes and blocked with 5% FBS for 30 minutes at room temperature. Then the section was stained with 10 µg/ml of anti-human CD20 (clone 2H7) Alexa Fluor® 647 (red) and 10 µg/ml of anti-human CD3 (clone UCHT1) Alexa Fluor® 488 (green) overnight at 4°C. The image was captured by 10X objective.

Description

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.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood. For immunohistochemical staining on frozen tissue sections, the suggested use of this reagent is 5.0 - 10 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633nm / 635nm.

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.

Related FAQs

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.

Our technical protocols can be found here.
