TACA
Based on 1 Customer Validation
TACA (trans-4-Aminocrotonic acid) is a potent agonist of GABAA and GABAC receptors (KD= 0.6 μM). TACA also is GABA uptake inhibitor and substrate for GABA-T. TACA produces late biphasic responses in the MPG neurons.

Solvente y solubilidad
H2O : 20 mg/mL (197.82 mM; ultrasonic and warming and heat to 60°C)
DMSO : < 1 mg/mL (insoluble or slightly soluble)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.
Add each solvent one by one: PBS
Solubility: 4 mg/mL (39.56 mM); Clear solution; Need ultrasonic and warming and heat to 60°C
