Attributs du produit: The MTS510 antibody reacts with the molecular complex of Toll-Like Receptor 4 and MD-2 (TLR4-MD-2) which is expressed on LPS responsive macrophages. TLR4, a member of the Toll-Like Receptor Family, has been renamed CD284 and identified to be the transmembrane signal-transducing portion of the receptor for LPS. TLR4 associates on the cell surface with CD14 and MD-2, a 0.7 kDa molecule which is anchored to the membrane via its physical association with TLR4. The association of MD-2 with TLR4 is required for recognition of LPS and the anti-mitotic compound Taxol, which mimics the action of LPS on mouse cells. MTS510 mAb detects TLR4-MD-2 on the surface of thioglycollate-elicited macrophages from all mouse strains tested (ie, BALB/c, C57BL/6, C3H/HeJ, C3H/HeN, and DBA/1), including the C3H/HeJ strain which expresses an LPS-resistant mutant TLR4. Expression of TLR4-MD-2 is down-regulated on peritoneal macrophages after exposure to LPS, correlating with the occurrence of LPS tolerance. TLR4-MD-2 is not detected on splenocytes or thymocytes. Expression of TLR4-MD-2 on peritoneal macrophages. Thioglycollate-elicited peritoneal macrophages from BALB/c mice were stained with either purified rat IgG2a, κ isotype control mAb R35-95 (Cat. No. 553927, left panel) or purified mAb MTS510 (right panel), in the presence of Mouse BD Fc Block™ purified anti-mouse CD16/CD32 mAb 2.4G2 (Cat. No. 553141/553142). Staining was detected by biotinylated anti-rat IgG2a mAb RG7/1.30 (Cat. No. 553894) then Streptavidin-PE (Cat. No. 554061). The macrophages were identified by staining with FITC-conjugated anti-mouse CD11b (Integrin αM chain) mAb M1/70 (Cat. No. 557396/553310). The total viable leukocytes are displayed. Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.
