Human SH2 domain containing leukocyte protein-76-Associated Phosphoprotein of 130kD (SLAP-130), also known as Fyb-120 and ADAP, is an 86kD, 783 amino acid, cytoplasmic protein that runs anomalously as a 120-130kD protein in SDS-PAGE. Human SLAP-130 is a hematopoietic-specific adaptor which associates with other cytoplasmic proteins such as SH2-containing Leukocyte Phosphoprotein of 76kD (SLP-76). Adaptors integrate signals from surface receptors and are essential components of many immune cell-signaling cascades. There is at least one known 46 aa longer alternatively-spliced SLAP-130 isoform. Over the region used as immunogen, SLAP-130 is 66% and 76% identical to the corresponding canine and mouse proteins, respectively.
Applications
Western Blot: This antibody can be used at 0.1-0.2ug/ml with the appropriate secondary reagents to detect human SLAP-130. The detection limit for rhSLAP-130 is approximately 1ng/lane under non-reducing and reducing conditions. Direct ELISA: This antibody can be used at 0.5-1.0ug/ml with the appropriate secondary reagents to detect human SLAP-130. The detection limit for rhSLAP-130 is approximately 0.2ng/well. Optimal dilutions should be determined by each laboratory for each application.
Storage and Stability
Lyophilized and reconstituted products are stable for 12 months after receipt at -20°C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20°C.
