体外実験

TT-012 inhibits the growth and metastasis of MITF-high melanoma cells by disrupting MITF dimer formation and DNA-binding ability[1].
TT-012 potently and specifically disrupts the dimerization of the human MITF bHLH-LZ domain in a cell-free AlphaScreen assay with an IC50 of 13.1 nM[2].
TT-012 specifically binds the MBP-fused human MITF bHLH-LZ domain in a cell-free SPR assay with a Kd of 15.5 nM[2].
TT-012 (5 μM; 8 h) systematically inhibits the MITF-mediated transcriptional network in B16F10 mouse melanoma cells, down-regulating 33 MITF target genes by more than 2-fold and selectively targeting MITF over other MiT/TFE family members[2].
TT-012 (72 h) potently inhibits the growth of high-MITF B16F10 mouse melanoma cells with an IC50 of 499 nM, with reduced activity in cells overexpressing MITF or the stable MITFΔ3 mutant, and shows selective activity against high-MITF melanoma cell lines[2].
TT-012 (10 μM; 1 h) increases the proportion of monomeric endogenous MITF in B16F10 mouse melanoma cells[3].
TT-012 (1 h) dose-dependently reduces endogenous MITF dimer formation in B16F10 mouse melanoma cells[3].
TT-012 (1.56-50 μM; 8 h) dose-dependently reduces mRNA levels of MITF target genes Tyr and Trpm1 in B16F10 mouse melanoma cells, with IC50 values less than 3.12 μM[3].

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.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

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.
