Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

应用

用于共价修饰蛋白质的半胱氨酸残基的试剂。

生化/生理作用

使 NADP 依赖性异柠檬酸脱氢酶和许多核酸内切酶失活的巯基烷化剂。
增强来自交感神经元的原生 M 通道的电流，并作为 KCNQ2、KCNQ4 和 KCNQ5 通道的开放剂。

制备说明

NEM 以 50mg/ml 的浓度溶于乙醇可得到透明的溶液。NEM 可溶于水（在 4ml 水中的溶解量 >50mg）；然而，水溶液却不稳定。水解速率为假一级，并显著依赖于 pH 值。

    Hv1 (also named, voltage-sensor only protein, VSOP) lacks an authentic pore domain, and its voltage sensor domain plays both roles in voltage sensing and proton permeation. The activities of a proton channel are intrinsic to protomers of Hv1, while Hv1

    The endocannabinoid 2-arachidonoylglycerol (2-AG) plays a major role in many physiological processes, and its action is quickly terminated via enzymatic hydrolysis catalyzed by monoglyceride lipase (MGL). Regulating its endogenous level could offer therapeutic opportunities; however, few selective MGL inhibitors have
