tatM2NX is a peptide generated by fusing part of the C-terminus of transient receptor potential melastin 2 (TRPM2) channels, corresponding more than 90% with the Nudix domain (M2NX), with the tat inducer of HIV. tatM2NX is a TRPM2 antagonist which prevents ligand binding and TRPM2 activation, and inhibits over 90% of human TRPM2 channel currents at concentrations as low as 2 μM. tatM2NX is an antagonist with an IC50 of 396 nM and is neuroprotective in animal models of focal and global ischemia.

Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides

Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.

Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.

Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.

In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.
