CU-T12-9 is a specific TLR1/2 agonist with EC50 of 52.9 nM in HEK-Blue hTLR2 SEAP assay. CU-T12-9 activates both the innate and the adaptive immune systems. CU-T12-9 selectively activates the TLR1/2 heterodimer, not TLR2/6. CU-T12-9 signals through NF-κB and invokes an elevation of the downstream effectors TNF-α, IL-10, and iNOS.

    Description

    CU-T12-9 is a specific TLR1/2 agonist with EC50 of 52.9 nM in HEK-Blue hTLR2 SEAP assay. CU-T12-9 activates both the innate and the adaptive immune systems. CU-T12-9 selectively activates the TLR1/2 heterodimer, not TLR2/6. CU-T12-9 signals through NF-κB and invokes an elevation of the downstream effectors TNF-α, IL-10, and iNOS[1].

    IC50 & Target[1]

    TLR2

    52.9 nM (EC50, in HEK-Blue cells)

    TLR1

    52.9 nM (EC50, in HEK-Blue cells)

    In Vitro

    CU-T12-9 directly targets TLR1/2 to initiate downstream signaling. By binding to both TLR1 and TLR2, CU-T12-9 facilitates the TLR1/2 heterodimeric complex formation, which in turn activates the downstream signaling[1].
    CU-T12-9 activates the TLR1/2 pathway by inducing NF-κB activation to trigger downstream signaling, such as secreted embryonic alkaline phosphatase (SEAP), NO, and TNF-α[1].
    CU-T12-9 (0.39-100 μM; 24 hours) does not produce toxicity up to 100 μM in HEK-Blue hTLR2 and Raw 264.7 cells[1].
    CU-T12-9 up-regulates the mRNA levels of TLR1, TLR2, TNF, IL-10, and iNOS. CU-T12-9 (0.1-10 μM) activates TLR1 mRNA and iNOS mRNA after Raw 264.7 cells are treated for 24 hours. CU-T12-9 (0.1-10 μM) activates TLR2 and IL-10 mRNA after Raw 264.7 cells are treated for 2 hours. CU-T12-9 (0.1-10 μM) activates TNF mRNA after Raw 264.7 cells are treated for 8 hours[1].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.08 mg/mL (5.74 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
