DHFR 蛋白, Human

目录号: HY-P701343
产品使用指南

DHFR 蛋白是叶酸代谢中的关键酶,对于多种途径至关重要。它催化线粒体胸苷酸从头生物合成、甘氨酸和嘌呤从头合成以及 DNA 前体合成所必需的反应。除了其催化作用之外,DHFR 还结合其自身的 mRNA 和 DHFR2 mRNA,这暗示着在自我表达控制中的调节作用以及对相关细胞过程的潜在影响。DHFR 蛋白, Human 是重组的 DHFR 蛋白,由 E. coli 表达,不带标签。DHFR 蛋白, Human 全长 187 个氨基酸。

描述

DHFR protein, a pivotal enzyme in folate metabolism, is crucial for multiple pathways. It catalyzes reactions essential for de novo mitochondrial thymidylate biosynthesis, de novo glycine and purine synthesis, and DNA precursor synthesis. Beyond its catalytic role, DHFR binds its own mRNA and DHFR2 mRNA, hinting at a regulatory role in self-expression control and potential influence on related cellular processes. DHFR Protein, Human is the recombinant human-derived DHFR protein, expressed by E. coli , with tag free. The total length of DHFR Protein, Human is 187 a.a., .

研究背景

二氢叶酸还原酶 (DHFR) 是叶酸代谢中的关键酶,在多种重要途径中发挥着至关重要的作用。它对从头线粒体胸苷酸生物合成途径有显着贡献,催化对从头甘氨酸和嘌呤合成以及 DNA 前体合成至关重要的反应。除了其催化功能外,DHFR 还表现出结合其自身 mRNA 和 DHFR2 mRNA 的能力,从而表明在控制其自身表达方面具有调节作用,并可能影响相关的细胞过程。

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
