  • BP000029-GD3: Recombinant Human FGF Acidic 136 (aa 19-155) Protein

    Source: E. coli-derived.
    The FGF acidic (aFGF/FGF-1/FGF1) activity is measured in a NIH/3T3 cell proliferation assay. The ED50 for this effect is typically 0.1-0.3 ng/ml in the presence of 10 ug/ml of heparin.
    Endotoxin: <1.0 EU per 1 ug of the protein by the LAL method.
    Purity: > 95% by SDS-PAGE under reducing conditions and visualized by silver stain.

  • BP000031-GD5: Recombinant Heparinase I from Flavobacterium heparinum

    Source: E. coli-derived.
    Specific activity >100 IU/mg. One international unit (IU) of recombinant Heparinase I is defined as the amount of enzyme that will liberate 1.0 umole unsaturated oligosaccharides from porcine mucosal heparin per minute at 30°C and pH 7.0.
    Purity >95% by SDS-PAGE.

  • BP000032-GD6: Recombinant Heparinase II from Flavobacterium heparinum

    Source: E. coli-derived.
    Specific activity >6 IU/mg. One international unit (IU) of recombinant Heparinase II is defined as the amount of enzyme that will liberate 1.0 umole unsaturated oligosaccharides from heparin or heparan sulfate per minute at 30°C and pH 7.3.
    Purity >95% by SDS-PAGE.

  • BP000033-GD7: Recombinant Heparinase III from Flavobacterium heparinum

    Source: E. coli-derived.
    Specific activity >50 IU/mg. One international unit (IU) of recombinant Heparinase III is defined as the amount of enzyme that will liberate 1.0 umole unsaturated oligosaccharides from heparan sulfate per minute at 30°C and pH 7.3.
    Purity >95% by SDS-PAGE.
