General Product Information

Bifunctional haem enzyme with catalase and peroxidase activtiy

Brown solid, lyophilized from 10 mM phosphate buffer, pH 7.0.

Reconstitution of 200 µg with 240 µl distilled water gives approximately 10 µM (per haem) Catalase-Peroxidase calculated with a molar extinction coefficient at 406 nm of 100 000 M^-1cm^-1

Stored below 0°C this lyophilized product is stable for years.

Overexpressed in Escherichia coli as soluble protein containing a hexa-histidine tag and purified by metal chelate affinity chromatography and gel filtration.
