TAT-EE3

😃Good
Catalog No. TP3908Cas No. 2899218-49-4

TAT-EE3 is a neuroprotective peptide that dissociates the interaction between TRPM2 and NMDARs. It inhibits the TRPM2-induced enhancement of NMDAR surface expression and current amplitude. TAT-EE3 protects neurons from ischemic damage both in vitro and in vivo, and is utilized for research on ischemic stroke.

Product Introduction

Bioactivity
Description
TAT-EE3 is a neuroprotective peptide that dissociates the interaction between TRPM2 and NMDARs. It inhibits the TRPM2-induced enhancement of NMDAR surface expression and current amplitude. TAT-EE3 protects neurons from ischemic damage both in vitro and in vivo, and is utilized for research on ischemic stroke.
In vitro
TAT-EE3 (10 μM, overnight) disrupts the interaction between TRPM2 and GluN2a/GluN2b in HEK293T cells and neurons, inhibiting TRPM2-induced enhancement of NMDA receptor surface expression and current amplitude. TAT-EE3 (10 μM, overnight) reduces OGD-induced intracellular Ca2+ overload, neuronal death, and mitochondrial depolarization in wild-type neurons, but has no effect on global TRPM2 knockout (gM2KO) neurons. TAT-EE3 (10 μM, 30-90 min) eliminates PMA-induced enhancement of NMDA receptor current in wild-type neurons without additional inhibitory effects on gM2KO neurons.
In vivo
Fifteen minutes prior to middle cerebral artery occlusion (MCAO), or every 12 hours post-MCAO for 7 days, TAT-EE3 (0.33 mg/kg [100 nmol/kg], administered via intraperitoneal injection) reduced infarct volume and improved neurological deficit scores in wild-type mice. However, this compound did not exhibit enhanced protective effects in neuron-specific TRPM2 knockout (nM2KO) mice.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
All types of co-solvents required for the protocol, such asDMSO, PEG300/ PEG400, Tween 80, SBE-β-CD, corn oil are available for purchase on the TargetMol website with a simple click.
