Specificity
The antibody MEM-53 reacts with CD53, a 32-40 kDa tetraspanin family glycoprotein exclusivelly expressed on leukocytes; it is not present on platelets, red blood cells and non-hematopoietic cells. _x000D_ The antibody MEM-53 reacts also with deglycosylated molecule (molecular weight of the antigen is reduced by 15 kDa using endoglycosidase F)._x000D_ HLDA IV; WS Code NL 59_x000D_ HLDA V; WS Code B CD53.5 _x000D_ HLDA V; WS Code BP BP287 _x000D_ HLDA V; WS Code T T-096 _x000D_ HLDA V; WS Code X XB004

Shipping and storage
Mouse Monoclonal Antibody against Human CD53, Clone: MEM-53 is transported on blue ice/ice packs and should be stored at temperatures between 1 and 5 degrees Celsius. Do not freeze! Avoid exposing the product to direct light, especially the conjugated antibodies as most conjugates are very sentitive to light.

Background
CD53 is a tetraspanin family transmembrane glycoprotein expressed in the lymphoid-myeloid lineage. This molecule has been reported to form complexes with other leukocyte surface proteins such as CD2, CD19, CD21, MHC II, VLA-4 or tetraspanins CD37, CD81 and CD82, thus probably modulating various signaling processes. CD53 is involved in radioresistancy of tumour cells and its triggering has anti-apoptotic effect. In thymus, CD53 is up-regulated in response to positive selection signals during T cell development, and is strongly expressed upon macrophage exposure to bacterial lipopolysaccharide, whereas stimulation of neutrophils results in down-regulation of CD53 expression.

About
Monoclonals of this antigen are available in different clones. Each murine monoclonal anibody has his own affinity specific for the clone. Mouse monoclonal antibodies are purified protein A or G and can be conjugated to FITC for flow cytometry or FACS and can be of different isotypes.
