Immunogen Leukocytes of pacient suffering from a LGL-type leukemia
Clone MEM-53
Isotype IgG1
Specificity The antibody 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. The antibody reacts also with deglycosylated molecule (molecular weight of the antigen is reduced by 15 kDa using endoglycosidase F).
Purification Protein-A affinity chromatography
Purity > 95 % pure (by SDS-PAGE)
Alternative Name CD53 (CD53 Antibody Abstract)
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.Synonyms: Cell surface glycoprotein CD53, Leukocyte surface antigen CD53, MOX44, TSPAN25, Tetraspanin-25
