描述

CD117/c-kit is a tyrosine protein kinase receptor for KITLG/SCF that coordinates cell survival, proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, migration, and melanogenesis. Upon KITLG/SCF binding, CD117 activates the pathway and phosphorylates PIK3R1, PLCG1, SH2B2/APS, and CBL. CD117/c-kit Protein, Human (P10721-2, HEK293, His) is the recombinant human-derived CD117/c-kit protein, expressed by HEK293 , with C-His labeled tag. The total length of CD117/c-kit Protein, Human (P10721-2, HEK293, His) is 491 a.a., with molecular weight of 75-85 kDa.

研究背景

CD117/c-kit 是一种酪氨酸蛋白激酶,作为细胞因子 KITLG/SCF 的细胞表面受体,在细胞存活、增殖、造血、干细胞维持、配子发生等细胞过程的协调中发挥着关键作用、肥大细胞发育、迁移和黑素生成。与 KITLG/SCF 结合后,KIT 激活多种信号通路,导致 PIK3R1、PLCG1、SH2B2/APS 和 CBL 磷酸化。AKT1 信号通路通过 PIK3R1(磷脂酰肌醇 3-激酶的调节亚基)的磷酸化被激活。此外,KIT 通过 GRB2 传输信号,激活 RAS、RAF1 和 MAP 激酶 MAPK1/ERK2 和/或 MAPK3/ERK1。此外,KIT 诱导 STAT 家族成员 STAT1、STAT3、STAT5A 和 STAT5B 的激活。PLCG1 激活导致二酰基甘油和肌醇 1,4,5-三磷酸的产生。蛋白磷酸酶调节 KIT 信号传导,受体经历快速内化和降解。激活的 KIT 促进涉及 PTPN6/SHP-1、PTPRU、STAT1、STAT3、STAT5A、STAT5B、PIK3R1、CBL、CRK(亚型 Crk-II)、LYN、MAPK1/ERK2 和/或 MAPK3/ERK1、PLCG1、SRC、和SHC1。

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
