Unit Definition: One international unit (IU) of heparinase I is defined as the amount of enzyme that will liberate 1.0 μmole unsaturated oligosaccharides from porcine mucosal heparin per minute at 35 ℃ and pH 7.0.

Stability: Expiration of heparinase I is 12 months from manufacturing date, frozen at -20 ℃ in PBS.

Applications
Heparinase I is useful in many applications (usually with heparinase II and heparinase III), for example:

For the neutralization of heparin in blood and plasma samples before analysis.
For similar in vitro neutralization of low molecular weight heparins.
As integral part of in vitro diagnostic tests for the neutralization of heparin (blood clotting tests, platelet tests).
In blood collection tubes for the neutralization of heparin.
For the preparation of low molecular weight heparins from unfractionated heparin.
As a research reagent (glycosaminoglycan degradation)
For the preparation of disaccharides of heparin and the preparation of oligosaccharide libraries.
