The Oxyrase® Enzyme System is an enzyme formulation derived from the cytoplasmic membrane of the microorganism, Escherichia coli, used as Nature’s Antioxidant® to produce anaerobic conditions in a wide variety of environments
EC-Oxyrase® consists of bacterial cell membrane fragments (in particulate suspension in 20mM Phosphate Buffer at a neutral pH) which creates an anaerobic environment when added to bacteriological medium by keeping oxygen from intruding into the medium. This eventually removes oxygen from head space of the sealed container used.
One unit of EC-Oxyrase® activity will reduce dissolved oxygen (in 1mL of air-saturated 40mM phosphate Buffer, pH 8.4, at 37°C) at the rate of 1% per second, and the rate of oxygen removal increases with temperature. However, EC-Oxyrase® is rapidly inactivated above 55°C. EC-Oxyrase® is active over a wide pH range of 6.8 to 8.4.
EC-Oxyrase® is filtered, sterilized, and aseptically packaged.
Ordering information: EC-Oxyrase® has a shelf life of 18 months under recommended storage and use conditions. Oxyrase® Inc. guarantees a minimum of 6 months shelf life from shipment date. If a longer shelf life is needed, this should be arranged at the time the order is placed (EC-Oxyrase® is shipped direct to customer.).
