Heparinase III Protein, P. heparinus (His)

Cat. No.: HY-P79211
SDS COA Handling Instructions

Heparinase III Protein is the unique member of the heparinase family of heparin-degrading lyases that recognizes the ubiquitous cell-surface heparan sulfate proteoglycans as its primary substrate. Heparinase III functions in cleaving metazoan heparan sulfate and providing carbon, nitrogen and sulfate sources for microorganisms. Furthermore, Heparinase III is cardioprotective in a dose-dependent manner, preserves endothelial function and attenuates PMN adherence to the coronary vascular endothelium. Heparinase III Protein, P. heparinus (His) is the recombinant Heparinase III protein, expressed by E. coli , with N-6*His labeled tag. The total length of Heparinase III Protein, P. heparinus (His) is 635 a.a., with molecular weight of ~74 kDa.

Background

Heparinase III is the unique member of the heparinase family of heparin-degrading lyases that recognizes the ubiquitous cell-surface heparan sulfate proteoglycans as its primary substrate. Heparinase III functions in cleaving metazoan heparan sulfate and providing carbon, nitrogen and sulfate sources for microorganisms. Heparinase III specifically cleaves heparan sulfate-rich regions of acidic polysaccharides. It acts primarily at the glycosidic linkage between N-sulfated or N-acetylated glucosamine (GlcNS or GlcNAc) and glucuronic acid (GlcA) as primary sites on the condition that the C2 GlcA is not sulfated. It can limit proliferation by affecting heparan sulfate proteoglycan binding growth factors following arterial injury. Furthermore, Heparinase III is cardioprotective in a dose-dependent manner, preserves endothelial function and attenuates PMN adherence to the coronary vascular endothelium[1][2][3][4].

Biological Activity

Measured by its ability to liberate oligosaccharides from heparin. Which can be measured by absorbance at 232 nm. The specific activity is 432.279935 pmol/min/µg, as measured under the described conditions.

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)
× = ×
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
