WASP (WAS, THC, IMD2, WASP, Eczema-thrombocytopenia)

Cat no: W0807-01

WASP (WAS, THC, IMD2, WASP, Eczema-thrombocytopenia)

The Wiskott-Aldrich syndrome (WAS) is an X-chromosome- linked recessive disease characterized by eczema, thrombocytopenia, and immunodeficiency (1). WAS is an immunodeficiency disorder with the most severe pathology in the T lymphocytes and platelets. The disease arises from mutations in the gene encoding the WAS protein (WASP). T lymphocytes of affected males with WAS exhibit a severe disturbance of the actin cytoskeleton, suggesting that the WASP could regulate its organization. Data suggest that the WASP might function as a signal transduction adaptor downstream of Cdc42, and in affected males, the cytoskeletal abnormalities may result from a defect in Cdc42 signaling (2). WASP is a key regulator of the Arp2/3 complex and the actin cytoskeleton in hematopoietic cells. WASP is capable of forming an auto-inhibited conformation, which can be disrupted by binding of Cdc42 and phosphatidylinositol 4,5-bisphosphate, leading to its activation. Stimulation of the collagen receptor on platelets and crosslinking the B-cell receptor induce tyrosine phosphorylation of WASP (3).\n\nApplications:\nSuitable for use in Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:10,000-50,000\nImmunohistochemistry: 1:100-1:250\nImmunocytochemistry: 1:100-1: 250\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. \n\nManufactured incorporating RabMAb(R) technology under Epitomics US patents, No 5,675,063 and 7,429,487, owned by Abcam.
