TYR Protein, Human (P.pastoris, His)

Cat. No.: HY-P71792
COA Handling Instructions

TYR protein, a copper-containing oxidase, initiates melanin production by catalyzing the hydroxylation of tyrosine to DOPA. This essential step is rate-limiting in the synthesis of melanins and polyphenolic compounds. TYR further enables the oxidation of DOPA to DOPA-quinone and potentially mediates the conversion of DHI to indole-5,6 quinone, playing a crucial role in the intricate cascade of reactions involved in melanin biosynthesis. TYR Protein, Human (P.pastoris, His) is the recombinant human-derived TYR protein, expressed by P. pastoris , with N-His, N-6*His labeled tag. The total length of TYR Protein, Human (P.pastoris, His) is 359 a.a., with molecular weight of ~48 kDa.

Background

TYR protein is a copper-containing oxidase crucial for pigment formation, playing a pivotal role in the synthesis of melanins and various polyphenolic compounds. Acting as the initiator of the melanin production pathway from tyrosine, TYR catalyzes the initial and rate-limiting step, hydroxylating tyrosine to DOPA (3,4-dihydroxyphenylalanine). Furthermore, it facilitates the oxidation of DOPA to DOPA-quinone and potentially mediates the oxidation of DHI (5,6-dihydroxyindole) to indole-5,6 quinone, contributing to the complex cascade of reactions involved in melanin biosynthesis.

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.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

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
