货号：SRP001 品名：合成的类维A酸 EC23 （4-（5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalen-2-ylethynyl） benzoic acid） 物理特性： 外观：白色粉末 分子式：C23H24O2 分子量：332 纯度：99%（HPLC） 保存： 合成的类维A酸 EC23可以在常规实验室条件下保持化学/物理性质的稳定。 可溶性： 与全反式维甲酸（ATRA）不同，EC23在溶液状态下对光线、加热和空气都不敏感。EC23不溶于水，微溶于乙醇，可以DMSO配制10mg/mL母液，或者以95%乙醇配制0.33mg/mL的母液，需要漩涡助溶。后续可溶于水溶液（包括细胞培养基）。溶液形式的EC23不会降解，保存EC23溶液时不必特别注意避光密封。 应用： EC23仅限科研使用，不可用于临床。实验表明，该化合物可以强力的诱导多能干细胞向神经组织方向分化，与ATRA相比，EC23能够稳定的诱导大量神经元分化。此外，EC23还能激活Hox基因转录子的表达。  参考文献：

Some retinoids can be troublesome, their lack of stability in light and susceptibility to degradation means it is impossible to know what dose you are really working with. ec23 is compley stable and the dose you add to your culture is exactly what you think it isevery time. For ease of use, ec23 comes in a clear glass vial. No more searching for your retinoid in dark glass. ec23 is a stable, synthetic retinoid which has been shown to be a potent inducer of both pluripotent stem cell and adult neuroprogenitor cell differentiation across a range of species.1-5

ec23 is stable; NMR of ec23 during prolonged exposure to light demonstrates clearly ec23 remains compley intact.
