IDO-2 Protein, Human (P.pastoris, His)

Cat. No.: HY-P71743
Handling Instructions

The IDO-2 protein plays a key role in cellular processes, catalyzing the initial and rate-limiting steps in the catabolism of the essential amino acid tryptophan in the kynurenine pathway. This enzymatic activity has been confirmed in multiple studies, establishing IDO-2 as a key regulator of tryptophan metabolism with important implications for immune regulation. IDO-2 Protein, Human (P.pastoris, His) is the recombinant human-derived IDO-2 protein, expressed by P. pastoris , with N-His labeled tag. The total length of IDO-2 Protein, Human (P.pastoris, His) is 407 a.a., with molecular weight of ~50.4 kDa.

Description

Background

Indoleamine 2,3-dioxygenase 2 (IDO-2) is an enzyme that catalyzes the first and rate-limiting step in the catabolism of the essential amino acid tryptophan along the kynurenine pathway. This pathway is crucial for the regulation of tryptophan metabolism and has implications in immune regulation. IDO-2's activity contributes to immune modulation by limiting tryptophan availability, which, in turn, affects immune cell function. While IDO-2 is involved in immune regulation, it may not play a significant role in tryptophan-related tumoral resistance, as suggested by certain studies.

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

Concentration (start) × Volume (start) = Concentration (final) × Volume (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
