Product name: SAP (SLAM-Associated Protein) Monoclonal Antibody (10C4.2), eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: This 10C4.2 monoclonal antibody reacts with human SLAM-associated protein (SAP). Upon SLAM receptor ligation, this 16-kDa SH2 domain-containing adaptor protein recruits Fyn tyrosine kinase, which phosphorylates the receptor to activate downstream signaling events. SAP is expressed in T, NK, and NKT cells, as well as eosinophils and platelets. This protein has also been detected in B cells and tumor cell lines such as Jurkat and Raji. Studies demonstrate that SAP expression in T follicular helper cells is required for germinal center formation. Moreover, this protein is involved in NKT cell development, Th1/Th2 differentiation, and controlling NK cytotoxicity. The role of SAP in B cells, however, is currently under investigation. Finally, deletion of the gene encoding SAP, SH2D1A, results in X-linked lymphoproliferative disease in humans.

Experimental details: 5 The NTB-A/SAP pathway impairs RICD in LR TB patients. PBMCs from healthy donors (HD, N =3), high responder tuberculosis patients (HR TB, N =3), low responder tuberculosis patients (LR TB, N =3) and SAP-deficient (XLP, N =1) patients were stimulated with Mtb -Ag for 5 days. Then, the cells were washed and cultured with RPMI plus hrIL-2. After 7 days, lymphocyte enrichment was performed by centrifugation over Ficoll-Hypaque and afterwards cells were stimulated with alpha-CD3+alpha-CD28 for 1 h. ( a ) Immunoprecipitation of NTB-A. The immunoprecipitates were separated by SDS-PAGE and immunoblotted for the presence of SAP, NTB-A and FYNT. SAP and FYNT expression in input lysates are shown for comparison (bottom) (I=Isotype, T0=unstimulated cells and 60''=stimulated cells with alpha-CD3+alpha-CD28 for 1 h). The images show cropped lines corresponding to NTB-A, SAP and FYNT. ( b ) Polyacrylamide gels were scanned, densitometry was performed, and the results were expressed as % FYNT IP with anti-NTB-A=([FYNT AU Immunoprecipitated fraction (IP)/(FYNT AU IP+FYNT AU Non-Immunoprecipitated fraction]) x 100. ( c ) PBMCs from HD ( N =6), HR ( N =7), LR ( N =5) tuberculosis patients and XLP ( N =3) patients were stimulated with Mtb -Ag for 5 days. Then, cells were washed and cultured with RPMI plus hrIL-2. After 7 days, lymphocyte enrichment was performed by centrifugation over Ficoll-Hypaque and cells were stimulated with alpha-CD3+alpha-CD28 for 24 h. Cell-free supernatants were collec
