    Human paraffin-embedded spleen tissue slices were prepared with a standard protocol of deparaffination and rehydration. Antigen retrieval was done with 1X Tris-EDTA buffer (pH 9.0) at 95°C for 40 minutes. Tissue was washed with PBS/ 0.05% Tween-20 twice for five minutes, blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with 10 µg/mL of purified anti-human CD20 (clone C20Mab-60) and 5 µg/mL of purified anti-human CD4 (clone A17070D) at 4°C overnight. On the next day, the tissue was washed twice with PBS and stained with Alexa Fluor® 647 anti-mouse IgG2a (red) and Alexa Fluor® 594 anti-mouse IgG2b (green) for two hours at room temperature. The nuclei were counterstained with DAPI (blue). The image was captured with a 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 ≤ 1.0 µg per million cells in 100 µL volume. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 5.0 - 10.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
