TNF-alpha/TNFSF2 蛋白, Sheep (P. pastoris, His)

目录号: HY-P700516
产品使用指南

TNF-α/TNFSF2 蛋白是一种巨噬细胞分泌的细胞因子,可与 TNFRSF1A/TNFR1 和 TNFRSF1B/TNFBR 结合,诱导肿瘤细胞死亡并充当热原。它与恶病质有关,刺激细胞增殖,促进分化,并诱导脂肪细胞中的胰岛素抵抗,从而导致 TNF 诱导的胰岛素抵抗。TNF-alpha/TNFSF2 蛋白, Sheep (P. pastoris, His) 是重组的 TNF-α/TNFSF2 蛋白,由 P. pastoris 表达,带有 N-6*His 标签。TNF-alpha/TNFSF2 蛋白, Sheep (P. pastoris, His) 全长 157 个氨基酸,分子量为 19.2 kDa。

描述

TNF-α/TNFSF2 protein is a macrophage-secreted cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR, inducing tumor cell death and acting as a pyrogen. It is associated with cachexia, stimulates cell proliferation, promotes differentiation, and induces insulin resistance in adipocytes, leading to TNF-induced insulin resistance. TNF-alpha/TNFSF2 Protein, Sheep (P. pastoris, His) is the recombinant sheep-derived TNF-alpha/TNFSF2 protein, expressed by P. pastoris , with N-6*His labeled tag. The total length of TNF-alpha/TNFSF2 Protein, Sheep (P. pastoris, His) is 157 a.a., with molecular weight of 19.2 kDa.

研究背景

TNF-α/TNFSF2 蛋白是一种细胞因子,可与 TNFRSF1A/TNFR1 和 TNFRSF1B/TNFBR 结合。它主要由巨噬细胞分泌,具有多种生物活性。它可以诱导某些肿瘤细胞系的细胞死亡,并充当强热原,通过直接作用或刺激白细胞介素-1 分泌而引起发烧。TNF-α/TNFSF2 蛋白也与恶病质的诱导有关。在特定条件下,能刺激细胞增殖,促进细胞分化。此外,它通过抑制胰岛素诱导的 IRS1 酪氨酸磷酸化和葡萄糖摄取来诱导脂肪细胞中的胰岛素抵抗,同时还导致 GKAP42 蛋白降解,从而导致 TNF 诱导的胰岛素抵抗。TNF-α/TNFSF2 蛋白通过与 IL1B 和 IL6 协同诱导 VEGF 产生,在血管生成中发挥作用。此外,它还促进破骨细胞生成,从而介导骨吸收。最后,TNF-α/TNFSF2 蛋白的 TNF 胞内结构域 (ICD) 形式可刺激树突状细胞中 IL12 的产生。

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
