SAP (SLAM-Associated Protein), eFluor 660, clone: XLP-1D12, eBioscience™
Rat Monoclonal Antibody
Manufacturer: Life Technologies LS50978741
This gene encodes a protein that plays a major role in the bidirectional stimulation of T and B cells. This protein contains an SH2 domain and a short tail. It associates with the signaling lymphocyte-activation molecule, thereby acting as an inhibitor of this transmembrane protein by blocking the recruitment of the SH2-domain-containing signal-transduction molecule SHP-2 to its docking site. This protein can also bind to other related surface molecules that are expressed on activated T, B and NK cells, thereby modifying signal transduction pathways in these cells. Mutations in this gene cause lymphoproliferative syndrome X-linked type 1 or Duncan disease, a rare immunodeficiency characterized by extreme susceptibility to infection with Epstein-Barr virus, with symptoms including severe mononucleosis and malignant lymphoma. Multiple transcript variants encoding different isoforms have been found for this gene.Description: The monoclonal antibody XLP-1D12 reacts with human SLAM-associated protein (SAP), which is also known as SH2D1A. SAP is a 15-kDa SH2 domain-containing adaptor protein. Upon CD150/SLAM family receptor ligation, SAP recruits Fyn tyrosine kinase, which phosphorylates the receptor to activate downstream signaling events. SAP is expressed in thymocytes, T cells, NK cells, and NKT cells. Studies have demonstrated a role for SAP in promoting follicular T helper cell differentiation during germinal center formation. In addition, this protein is involved in NKT cell development, Th1/Th2 differentiation, development of innate T cells, and regulation of NK cell and CD8+ T cell cytotoxicity. Mutations of the gene encoding SAP results in X-linked lymphoproliferative (XLP) syndrome, which is characterized by impaired humoral immunity leading to increased susceptibility to Epstein-Barr virus infection and/or lymphoma. SAP has also been linked to automimmune diseases such as systemic lupus erythematosus.Applications Reported: This XLP-1D12 antibody has been reported for use in intracellular staining followed by flow cytometric analysis.Applications Tested: This XLP-1D12 antibody has been pre-titrated and tested by intracellular staining and flow cytometric analysis of normal human peripheral blood cells using the Foxp3/Transicription Factor Staining Buffer Set (cat. 00-5523) and protocol. Please refer to Best Protocols: Protocol B: One step protocol for (nuclear) intracellular proteins located under the Resources tab online. This can be used at 5 μL (0.03 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. eFluor™ 660 is a replacement for Alexa Fluor™ 647. eFluor™ 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome.Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser.Filtration: 0.2μm post-manufacturing filtered.
