Semaphorin-5A/SEMA5A 蛋白, Human (HEK293, Fc)

目录号: HY-P74560
产品使用指南

Semaphorin-5A/SEMA5A 蛋白充当双功能轴突引导信号,通过硫酸乙酰肝素蛋白聚糖产生吸引作用,并通过硫酸软骨素蛋白聚糖产生抑制作用。作为 PLXNB3 受体的配体,SEMA5A 会破坏神经胶质瘤细胞的迁移和侵袭,诱导细胞崩溃。它还可能通过影响内皮细胞增殖和迁移来促进血管生成,同时抑制细胞凋亡。SEMA5A 与 PLXNB3 的结合揭示了其在正常和病理条件下的轴突引导、细胞迁移和血管生成中的多种作用。Semaphorin-5A/SEMA5A 蛋白, Human (HEK293, Fc) 是重组的 Semaphorin-5A/SEMA5A 蛋白,由 HEK293 表达,带有 C-hFc 标签。Semaphorin-5A/SEMA5A 蛋白, Human (HEK293, Fc) 全长 765 个氨基酸,分子量为 125-135 kDa。

描述

Semaphorin-5A/SEMA5A Protein acts as a bifunctional axonal guidance cue, with attractive effects via heparan sulfate proteoglycans and inhibitory effects through chondroitin sulfate proteoglycans. As a ligand for PLXNB3 receptor, SEMA5A disrupts glioma cell migration and invasion, inducing cellular collapse. It may also promote angiogenesis by affecting endothelial cell proliferation and migration, while inhibiting apoptosis. SEMA5A's binding to PLXNB3 reveals its diverse roles in axon guidance, cell migration, and angiogenesis in both normal and pathological conditions. Semaphorin-5A/SEMA5A Protein, Human (HEK293, Fc) is the recombinant human-derived Semaphorin-5A/SEMA5A protein, expressed by HEK293, with C-hFc labeled tag. The total length of Semaphorin-5A/SEMA5A Protein, Human (HEK293, Fc) is 765 a.a., with molecular weight of 125-135 kDa.

研究背景

Semaphorin-5A/SEMA5A 蛋白作为受硫酸化蛋白聚糖调节的双功能轴突导向信号发挥作用,通过与硫酸乙酰肝素蛋白聚糖 (HSPG) 的相互作用表现出有吸引力的效果,并通过与硫酸软骨素蛋白聚糖 (CSPG) 的相互作用表现出抑制作用。作为受体 PLXNB3 的配体,SEMA5A 在神经胶质瘤细胞中发挥着至关重要的作用,其对 PLXNB3 的刺激导致 F-肌动蛋白应力纤维解体、粘着斑破坏、细胞塌陷以及通过 AHGDIA 抑制细胞迁移和侵袭。- RAC1 介导的失活。此外,SEMA5A 可能通过增强内皮细胞增殖和迁移同时抑制细胞凋亡来促进血管生成。SEMA5A 与 PLXNB3 的结合强调了它参与多种细胞过程,为了解其在正常发育和病理条件下的潜在作用提供了宝贵的见解,特别是在轴突引导、细胞迁移和血管生成方面。

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
