OriGene mouse anti tlr2 monoclonal antibody mab
(a) FACS analysis of CEACAM1 and <t>TLR2</t> (black lines) expression on the cell surface of NHBE cells. Grey lines represent isotype-matched control mAb staining. (b, c and d) ELISA for IL8 and IL6, respectively, in supernatants of NHBE cells incubated with Pam 3 Cys alone, with Pam 3 Cys plus soluble CEACAM8-Fc and rat-CEACAM1-Fc, respectively (100 ng/ml each) or left untreated for 16 h. (e) 50 ng purified protein of CEACAM8-Fc and ratCEACAM1-Fc were analyzed by SDS-PAGE and stained by Coomassie blue to demonstrate equal amount and integrity of the used fusion proteins. (f) FACS analysis CEACAM1 and TLR2 expression (black lines) on the surface of A549 cells. Grey lines represent the isotype-matched control. (g) IL-8 released into the supernatants of A549 cells pre-incubated for 1 h with anti-CEACAM1 (mAb 18/20) or left untreated followed by stimulation with Pam 3 Cys alone or with Pam 3 Cys and CEACAM8-Fc and ratCEACAM1-Fc, respectively (100 ng/ml) for 16 h. Samples were measured by commercial ELISA. IL8 secretion following treatment of the cells with Pam3Cys served as positive control. (h) A549 cells were challenged either with CEACAM8-Fc or with mAb 18/20 (20 ng/ml). The IgG antibody was used as control. Cell lysates were assessed after CEACAM1 immunoprecipitation with anti-phospho tyrosine mAb 4G10 (upper panel). Then membrane was stripped and re-probed with anti-CEACAM1 mAb (lower panel) to measure the amount of precipitated CEACAM1. Data presented in (a, e, f and h) are from one experiment representative of three independent experiments, and the data presented in (b, c, d and g) are mean ± s.e.m. of three different experiments performed in triplicates, * P<0.05.

Cell lysates were assessed after CEACAM1 immunoprecipitation with anti-phospho tyrosine mAb 4G10 (upper panel). Then membrane was stripped and re-probed with anti-CEACAM1 mAb (lower panel) to measure the amount of precipitated CEACAM1. Data presented in (a, e, f and h) are from one experiment representative of three independent experiments, and the data presented in (b, c, d and g) are mean ± s.e.m. of three different experiments performed in triplicates, * P<0.05.

Article Snippet: After blocking with 10% FCS in PBS for 10 min, 0.5×10 6 cells were incubated with 10 µg/ml mouse anti-TLR2 monoclonal antibody (mAb) (Acris Antibodies GmbH, Herford, Germany) or 3.5 µg/ml anti-CEACAM1 mAb 18/20 (B.B.
