![TLR4 Inhibitor Peptide Set [NBP2-26244] - The inhibitor peptide inhibits TLR4 signaling by blocking interactions between TLR4 and its adaptors Mal/TIRAP and TRAM.](http://images.novusbio.com/fullsize/TLR4-Inhibitor-Peptide-Set-NBP2-26244-img0013.jpg "TLR4 Inhibitor Peptide Set [NBP2-26244] - The inhibitor peptide inhibits TLR4 signaling by blocking interactions between TLR4 and its adaptors Mal/TIRAP and TRAM.")
![Blocking/Neutralizing: TLR4 Inhibitor Peptide Set [NBP2-26244] - iBMDM cultures were pretreated with 5uM of inhibitor or control prior to stimulation with 20 ng/ml LPS. Negative (LPS-, LPS-/CP7+, LPS-/CP7+) and positive (LPS+) controls were also included. Supernatants were harvested after 6 h and murine TNF-alpha measured by ELISA. TLR4 inhibitor, but not the control, inhibited LPS-induced TNF-alpha production.

![TLR4 Inhibitor Peptide Set [NBP2-26244] - TLR4/MD-2/CD14/NF-kB/SEAPorter stably transfected cells were plated in 96-well plates at 1x10^5 cells/well. After 16 h, cells were preincubated with various concentrations of inhibitor or control peptides (CP) for 1 h. Cells were then stimulated with 10 ng/ml LPS for 24 h. The secreted alkaline phosphatase (SEAP) was analyzed using the SEAPorter Assay Kit. Inhibitory effect on the LPS-mediated TLR4 activation by the VIPER peptide is shown in panel A, and IC50 of the VIPER peptide is described in panel B.](http://images.novusbio.com/fullsize/TLR4-Inhibitor-Peptide-Set-Blocking-Neutralizing-NBP2-26244-img0016.jpg)
![TIRAP (TLR2 and TLR4) Inhibitor Peptide [NBP2-26245] - TLR2 acts through formation of heterodimer complexes with TLR1 or TLR6. HEK 293 endogenously expresses TLR1 and TLR6, so that the TLR2 reporter cell line can response to both Pam3CSK4 (TLR2/TLR1 specific ligand) and MALP-2 (TLR2/TLR6 specific ligand). The TLR2 / TLR4 inhibitor specifically inhibits TLR2/TLR1 receptor complex activity in a dose-response manner but exhibited no or little effect on TLR2/TLR6 receptor complex activity.](http://images.novusbio.com/fullsize/TIRAP-TLR2-and-TLR4-Inhibitor-Peptide-NBP2-26245-img0007.jpg "TIRAP (TLR2 and TLR4) Inhibitor Peptide [NBP2-26245] - TLR2 acts through formation of heterodimer complexes with TLR1 or TLR6.

![TIRAP (TLR2 and TLR4) Inhibitor Peptide [NBP2-26245] - TLR2 /4 Inhibitor suppressed the Pam3CSK4-induced TLR2/TLR1 activity [A] and the LPS-induced TLR4 activity [B] in a dose-response manner, of which IC50 values were measured as 17.2 uM and 10.47 uM, respectively.](http://images.novusbio.com/fullsize/TIRAP-TLR2-and-TLR4-Inhibitor-Peptide-NBP2-26245-img0009.jpg)
