General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Hydrolysis and regioselective transesterification catalyzed by immobilized lipases in membrane bioreactors[Reference: WebLink]

An experimental study of two types of immobilized lipase membrane reactors for the bioconversion of lipophilic substrates is reported.
METHODS AND RESULTS:
In one part of the work, the performance of biphasic membrane reactors has been investigated as a function of selected operating conditions for the hydrolysis of olive oil. In this type of reactor, aqueous and organic phases flow tangentially past the two surfaces of an enzyme containing membrane; intramembrane mass transfer is diffusive.Another part of the study refers to the regioselective transesterification of 5,7-Diacetoxyflavone in a monophasic non-aqueous membrane reactor wherein an organic phase solution of substrate is crossflow filtered through the wall of a tubular enzyme-loaded membrane; in this case, intramembrane mass transfer is convective.Immobilization of the enzyme both within the interior of the membranes and at their surfaces is considered.The influence of fluid dynamics parameters and immobilization site on the biphasic reactors performance has been studied using lipase from Candida rugosa.
CONCLUSIONS:
The effect of immobilization, of the amount of immobilized enzyme on the catalytic activity and regioselectivity efficiency in non aqueous system have been investigated using lipase from Pseudomonas cepacea.
