Description

D-GsMTx4 TFA is a spider peptide and the D enantiomer of GsMTx4 (HY-P1410). D-GsMTx4 TFA inhibits the mechanosensitive ion channel Piezo2. D-GsMTx4 TFA inhibits [Ca2+]i elevation. D-GsMTx4 TFA inhibits mTOR and PI3K-Akt signaling pathways. D-GsMTx4 TFA inhibits mechanical allodynia and thermal hyperalgesia. D-GsMTx4 TFA can be used in researches of mechanical stress, chronic pain and idiopathic pulmonary fibrosis[1][2][3][4].

In Vitro

D-GsMTx4 (5-10 µM) TFA dose-dependently and reversibly inhibits Piezo2-mediated mechanosensitive inward currents in QGP-1 cells and human Piezo2-transfected HEK-293 cells[1].
D-GsMTx4 TFA decreases phosphorylation levels of proteins in the mTOR and PI3K-Akt signaling pathways in primary human lung fibroblasts (HLFs)[2].
D-GsMTx4 (5 µM) TFA inhibits mechanical stimulation-evoked [Ca2+]i increases in cultured DRG neurons from CYP-induced cystitis rats[3].

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    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL; Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

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.
