Hirudin Protein, Poecilobdella viridis (P. pastoris)

Cat. No.: HY-P72799
COA Handling Instructions

Hirudin Protein, a powerful thrombin-specific protease inhibitor, forms a stable non-covalent complex with alpha-thrombin, effectively preventing fibrinogen cleavage. This interaction underscores hirudin's critical role in regulating key coagulation cascade steps. Its specific thrombin inhibition emphasizes hirudin's significance as a therapeutic agent, particularly for precise blood clotting regulation. Hirudin Protein, Poecilobdella viridis (P. pastoris) is the recombinant Hirudin protein, expressed by P. pastoris , with tag free. The total length of Hirudin Protein, Poecilobdella viridis (P. pastoris) is 63 a.a., with molecular weight of ~6.7 kDa.

Description

Hirudin Protein, a powerful thrombin-specific protease inhibitor, forms a stable non-covalent complex with alpha-thrombin, effectively preventing fibrinogen cleavage. This interaction underscores hirudin's critical role in regulating key coagulation cascade steps. Its specific thrombin inhibition emphasizes hirudin's significance as a therapeutic agent, particularly for precise blood clotting regulation. Hirudin Protein, Poecilobdella viridis (P. pastoris) is the recombinant Hirudin protein, expressed by P. pastoris , with tag free. The total length of Hirudin Protein, Poecilobdella viridis (P. pastoris) is 63 a.a., with molecular weight of ~6.7 kDa.

Background

Hirudin Protein emerges as a potent thrombin-specific protease inhibitor, showcasing its ability to form a stable non-covalent complex with alpha-thrombin. This interaction results in the effective abolition of alpha-thrombin's capacity to cleave fibrinogen, underscoring the critical role of hirudin in modulating key steps in the coagulation cascade. The specific and targeted inhibition of thrombin by hirudin highlights its significance as a therapeutic agent, particularly in contexts where precise regulation of blood clotting is essential.

Biological Activity

The biological activity is determined by chromogenic assay, 1 unit is defined as the amount of Hirudin that neutralizes 1 unit of the WHO preparation 89/588 of thrombin. The specific activity is no less than 14,000 ATU/mg protein.

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.

  • 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
