MW: 130,000-150,000
Extinction Coefficient: 1.45

Lyophilized from 50 mM Na acetate, pH 6.0 with 100 mM NaCl

This heme protein catalyzes oxidations by hydrogen peroxide, including MPO- chloride mediated killing of microbes and tumor cells, inactivation of hemotactic factors, crosslinking of proteins and inclination of proteins.

Activity: 180-220 units per mg protein after lyophilization. One unit is defined as the amount of enzyme that decomposes one umole of hydrogen peroxide per minute at 25oC , pH 6.0. Reaction mixture contains 30mM sodium phosphate, pH 6.1, 30mM guaiacol, and 0.0012% (0.35mM) hydrogen peroxide.

Storage: -20°C

Purity: >=95% by SDS-PAGE

Prepared from whole blood shown to be non reactive for HBsAg, anti-HCV, anti- HBc, and negative for anti-HIV 1 & 2 by FDA approved tests.
