描述

KYNU, also known as Kynureninase protein, catalyzes the conversion of L-kynurenine and L-3-hydroxykynurenine into anthranilic acid and 3-hydroxyanthranilic acid, respectively. It displays a preference for the L-3-hydroxy form and possesses cysteine-conjugate-beta-lyase activity as well. KYNU/Kynureninase Protein, Mouse (sf9, His) is the recombinant mouse-derived KYNU/Kynureninase protein, expressed by Sf9 insect cells , with C-His labeled tag. The total length of KYNU/Kynureninase Protein, Mouse (sf9, His) is 464 a.a., with molecular weight of ~47 kDa.

研究背景

KYNU 蛋白被称为犬尿氨酸酶,在 L-犬尿氨酸 (L-Kyn) 和 L-3-羟基犬尿氨酸 (L-3OHKyn) 的分解中发挥着关键作用,将它们转化为邻氨基苯甲酸 (AA) 和 3-羟基邻氨基苯甲酸 ( 3-OHAA)相应地。它对 L-3-羟基形式表现出特异性亲和力,并具有额外的半胱氨酸缀合物-β-裂合酶活性。

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
