uniprot entry name :
CD20_HUMAN
reactivity :
Cynomolgus monkey, Rhesus Monkey
specificity :
Clone L26, a mouse anti human CD20 antibody, recognizes the human CD20 cell surface antigen, a 33-37 kDa non-glycosylated phosphoprotein. The CD20 antigen is expressed during pre-B-cell development. It is present on both resting and activated B-cells but is lost prior to terminal B-cell differentiation into plasma cells. Clone L26 recognizes a cytoplasmic epitope of CD20.
form :
Concentrate. Tissue Culture Supernatant - liquid
storage stability :
Store at 4 degree C or at -20 degree C if preferred. Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use. Shelf Life: 18 months from date of despatch.
tested application :
Immunohistology Frozen, Immunohistology Paraffin
app notes :
Immunohistology: This product does not require protein digestion pre-treatment of paraffin sections. This product does not require antigen retrieval using heat treatment prior to staining of paraffin sections. Immunohistology - Frozen: Minimum Dilution: 1/10; Maximum Dilution: 1/40. Immunohistology - Paraffin: Minimum Dilution: 1/10; Maximum Dilution: 1/40

ncbi summary :
This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. This gene encodes a B-lymphocyte surface molecule which plays a role in the development and differentiation of B-cells into plasma cells. This family member is localized to 11q12, among a cluster of family members. Alternative splicing of this gene results in two transcript variants which encode the same protein.

uniprot summary :
MS4A1: This protein may be involved in the regulation of B-cell activation and proliferation. Defects in MS4A1 are the cause of immunodeficiency common variable type 5 (CVID5); also called antibody deficiency due to CD20 defect. CVID5 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be low. Belongs to the MS4A family. Protein type: Membrane protein, integral; Membrane protein, multi-pass; Cell surface. Chromosomal Location of Human Ortholog: 11q12. Cellular Component: extracellular space; integral to plasma membrane; external side of plasma membrane. Molecular Function: epidermal growth factor receptor binding. Biological Process: B cell proliferation; humoral immune response. Disease: Immunodeficiency, Common Variable, 5
