描述

The TRPA1 protein is a receptor-activated nonselective cation channel that is critical for pain detection and may affect cold sensation, oxygen sensing, cough reflex, itch, and inner ear function. It responds to inflammatory mediators and irritants such as allyl thiocyanate (AITC), cinnamic aldehyde, diallyl disulfide (DADS), and acrolein. TRPA1 Protein, Human (HEK293, His, MBP, FLAG) is the recombinant human-derived TRPA1 protein, expressed by HEK293 , with N-10*His, N-MBP, C-Flag labeled tag. The total length of TRPA1 Protein, Human (HEK293, His, MBP, FLAG) is 1118 a.a. .

研究背景

TRPA1 蛋白作为受体激活的非选择性阳离子通道,在疼痛检测中发挥着至关重要的作用,并可能有助于冷觉、氧浓度感知、咳嗽反射、瘙痒和内耳功能。TRPA1 对二价阳离子的偏好是单价阳离子的 8 倍,它参与了对内源性炎症介质和各种刺激物的疼痛反应,例如芥子油中的烯丙基硫氰酸酯 (AITC)、肉桂醛、大蒜中的二烯丙基二硫化物 (DADS) 和泪液中的丙烯醛煤气和汽车尾气。此外,TRPA1 还充当离子型大麻素受体,对大麻的精神活性成分 δ(9)-四氢大麻酚 (THC) 做出反应。激活通过结构上不相关的亲电和非亲电化合物发生,亲电配体与关键的 N 末端 Cys 残基共价相互作用。TRPA1 还可能作为内耳毛细胞中机械敏感转导通道的一个组成部分,有助于声音感知。它的激活受到胞质因子(可能是焦磷酸盐或多磷酸盐)的调节,从而维持 TRPA1 处于激动剂敏感状态。此外,TRPA1 可被各种阻滞剂抑制,包括钌红、A-967079、AP-18、HC-030031 和芳基磺酰胺衍生物 ASD,而蝎子芥末受体毒素和各种化学试剂可实现非共价激活。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
