描述

Catalase Protein, Human is an approximately 60.0 kDa human catalase protein expressed in E.coli. Catalase is a key enzyme in metabolism of H2O2 and reactive nitrogen species, and its expression and localization is markedly altered in tumors[1].
研究背景

过氧化氢酶是人体防御氧化应激的关键抗氧化酶。过氧化氢酶将活性氧过氧化氢转化为水和氧气，从而减轻过氧化氢的毒性作用[1][2]。
生物活性

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.

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
