Preparation
Method
Preparation of 2.5 mM peptide stock solutions
TLR2 / TLR4 Inhibitor Peptide: A final volume of 100 ul will make a 2.5 mM stock solution. Add 100 ul sterile water to the tube of peptide. Carefully pipet to ensure all of the peptide is dissolved and briefly spin the tube before opening.

Antennapedia Control Peptide: A final volume of 170 ul will make a 2.5 mM stock solution. Add 170 ul sterile water to the tube of peptide. Carefully pipet to ensure all of the peptide is dissolved and briefly spin the tube before opening.

The stock solutions may be diluted further to make working solutions. Dilute according to the needs for your assay. For example, dilute 2.5 mM stock solutions 1:10 in sterile 1X PBS or cell culture media to make 250 uM working solutions. Working solution should be made fresh daily and not be stored.

Applications/Dilutions

Application Notes
The inhibitor is used in assays to inhibit TLR2 and TLR4 signaling. We recommend an initial titration of the inhibitor from 0-50 uM for in vitro assays along with control of which concentrations should be mirror inhibitor concentrations. Inhibitor and control should be preincubated with cells prior to ligand activation to allow sufficient time for the peptides to enter from the media into the cell. We typically preincubate with inhibitor and control for 1 h prior to TLR2 or TLR4 activation (Figures 1 and 2); however, optimal preincubation times may vary between model systems. The TLR2/NF-kB/SEAPorter™ cell line and TLR4/MD2/CD14/NF-kB/SEAPorter™ cell line are a useful positive control model system for studying inhibition of TLR2 and TLR4 activation, respectively (Figures 1 through 3). Use in In vitro assay reported in scientific literature (PMID 26908090). Use in FLOW cytometry reported in scientific literature (PMID 27838489).

Background

TIRAP/Mal is an adapter protein in the signaling pathways activated by TLR2 and TLR4, and appears to be essential for MyD88-dependent TLR2 and TLR4 signaling pathways. TIRAP is recruited to activated TL2 and TLR4 through interaction with TIR domain of the receptor. This peptide contains a sequence from mouse TIRAP that blocks the function of TIRAP, likely through binding to the receptor and blocking TIR-TIR domain interaction between TIRAP and the receptor.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Inhibitors are guaranteed for 1 year from date of receipt.

FAQs for TIRAP (TLR2 and TLR4) Inhibitor (NBP2-26245). (Showing 1 - 2 of 2 FAQs).

  1. What is the advantage of NBP2-26245 over NBP2-29331? Both of them are TIRAP Inhibitory Peptides but I do not see in the literature provided in the webepage why I would choose one over the other? Or why would I spend more on NBP2-26245?
    • While both of these peptides serve the same function, there are differences in the functional sequence. I would like to direct you to to two attached articles in regards to this. 1. NBP2-26245 (Piao, 2013), sequence is shown in Figure 3G, labelled as mTIRAP 2. NBP2-29331: (Shilling 2002), sequence is described under Reagents and Abs on page 5875. All things aside, we have extensive testing data for NBP2-26245 from in-house testing, whereas we are still in the process of validating NBP2-29331 in-house. We can offer much better support for NBP2-26245 so this is the product I would recommend.
  2. Our customer has a question about NBP2-26245. Inhibitors are guaranteed for 1 year from date of receipt is described on the product page. However, the customer said that their project may last longer, and they cannot ensure when the product will be applied. Would you please help check and suggest the expiry date of the newest lot of NBP2-26245?
    • We do not state expiry dates on our products however, as you rightly point out, our TIRAP (TLR2 and TLR4) inhibitor peptide set with catalogue number NBP2-26245 is guaranteed for 1 year from the date of receipt. Upon receipt of the product I recommend that your customer stores it in its lyophilised form at -20C or -80C until they actually need to use it, since lyophilised products are more stable than liquids. Upon reconstitution they should aliquot the product and store it at -20C or -80C, avoiding freeze-thaw cycles. We do not have any testing data regarding the stability of this product beyond a year and cannot guarantee it beyond this time.
