Klotho 蛋白, Human (CHO, His)

目录号: HY-P700011
COA 产品使用指南

Klotho 蛋白 对葡萄糖醛酸化类固醇表现出较弱的糖苷酶活性,并且由于缺乏必需的活性位点 Glu 残基,在体内无活性。它通过抑制活性维生素 D 的合成来调节钙和磷的稳态。Klotho 蛋白, Human (CHO, His) 是重组的 Klotho 蛋白,由 CHO 表达,带有 C-10*His 标签。Klotho 蛋白, Human (CHO, His) 全长 948 个氨基酸,分子量为 120-140 kDa。

描述

Klotho Protein exhibits weak glycosidase activity against glucuronidated steroids and is inactive in vivo due to the lack of essential active site Glu residues. It regulates calcium and phosphorus homeostasis by inhibiting the synthesis of active vitamin D. Klotho Protein, Human (CHO, His) is the recombinant human-derived Klotho protein, expressed by CHO , with C-10*His labeled tag. The total length of Klotho Protein, Human (CHO, His) is 948 a.a., with molecular weight of 120-140 kDa.

研究背景

Klotho 蛋白对葡萄糖醛酸化类固醇表现出较弱的糖苷酶活性,但由于 239 和 872 位缺少必要的活性位点 Glu 残基,表明其在体内作为糖苷酶无活性。此外,Klotho 可能在钙和磷的调节中发挥作用通过抑制活性维生素 D 的合成来维持体内平衡。作为 FGF23 和 FGFR1 之间特异性相互作用的重要因素,Klotho 有助于关键的信号传导通路。此外,通过裂解膜结合异构体产生的 Klotho 肽被认为可以作为抗衰老循环激素。这种激素有可能通过抑制胰岛素/IGF1 信号传导来延长寿命,使 Klotho 成为一种多功能蛋白质,对代谢调节和衰老过程都有影响。

生物活性

The EC50 as determined by the dose-dependent stimulation of the proliferation of murine NIH/3T3 is less than 1 μg/mL.

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)
× = ×
C1   V1   C2   V2

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
