产品详情
(R)-Trolox 是维生素 E 类似物,是一种竞争性酪氨酸酶抑制剂,Ki 值为 0.83 mM,ID50 值为 1.88 mM。(R)-Trolox 具有比 (S) 对映异构体更强的酪氨酸酶亲和力 (Ki 值为 0.61 mM)。
生物活性
(R)-Trolox is a vitamin E analogue and a competitive tyrosinase inhibitor with a K i value of 0.83 mM and a ID 50 value of 1.88 mM. The (R)-Trolox has stronger tyrosinase affinity than the (S) enantiomer (K i value of 0.61 mM).
性状
Solid
体外研究(In Vitro)
As compared to the control containing no inhibitor, DMSO suppresses the tyrosinase activity at tested levels, 100 and 200 μL in a total volume of 3.0 mL. The inhibition of DMSO on the mushroom tyrosinase is dosedependent. Additions of DMSO at the two levels in the tyrosinase digests containing (R)-Trolox ((R)-HTCCA) results in further inhibitions of the tyrosinase activity. The influence of the DMSO on the inhibitory effects of (R)-Trolox against the tyrosinase is also dose-dependent. has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
