Western blot analysis of extracts from Ramos(lane 2, 20μg), Raji(lane 3, 20μg), Daudi(lane 4, 20μg) and HeLa(lane 5, 20μg) using CD20 Antibody (HY-P81558). Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hours at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80993, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (HY-P8001, 1/10000) was used for 1 hour at room temperature.

Flow cytometric analysis of 1X10^6 Raji cells labeling CD20 Antibody (HY-P81558, red). Cells were stained with the primary antibody at 1/100 dilution for an hour at 4℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L (HY-P8002) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Rabbit IgG Isotype Control (HY-P80879, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
Background

Function
CD20 is a 33-37 kDa non-glycosylated protein expressed specifically on the surface of normal and malignant B lymphocytes, and belongs to the MS4A (membrane-spanning 4-domain family A) protein family. CD20 is a general B-cell marker expressed by the majority of B cells starting from late pre-B lymphocytes (it is not expressed by pro-B lymphocytes), and its expression is lost in terminally differentiated plasmablasts and plasma cells. Early experiments suggested that it was important in the regulation of human B-cell activation, proliferation, and Ca2+ transport. However, CD20-deficient mice appeared normal. Hence, the exact biological function of CD20 and its physiological ligand remain to be fully defined.240 Regardless of the uncertainty in the biological role of this antigen, it is a good target for cancer immunotherapy.

Isoforms & Post-Translational Modification
CD20 has 2 isomers: P11836-1: 33077 Da (predicted); P11836-2: 14581 Da (predicted).
Phosphorylated on serines and threonines in resting B-cells. Protein kinase C/PKC can use CD20 as substrate -
Subunit
Forms homotetramers (PubMed:18474602, PubMed:7684739). Interacts with the heavy and light chains of cell surface IgM, the antigen-binding components of the BCR (PubMed:18474602)
