Description
Enzymes are molecules that accelerate chemical reactions. In these reactions, the molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products.
Most enzymes are proteins.
An enzyme’s activity decreases markedly outside a narrow range of temperature and pH.
Characteristics
All enzymes are accompanied by product information sheets which describe proper storage conditions.
All products which are formulated with either glycerol/H2O or aqueous buffer are delivered in microcentrifuge tubes. By briefly centrifuging the samples in their original containers, complete recovery of the sample at the bottom of the tube will be accomplished.
All products which are formulated with glycerol/H2O should be stored at -20° C and remain in fluid phase. Temperatures lower than -30° C should be avoided in order to prevent a phase transition.
When preparing to make a dilution of the stock sample, remove the sample from storage at -20° C and place on ice for a brief period of time (5-10 min). The sample will become less viscous and thus easier to pipette.
Never allow protein solutions to remain at room temperature for excessive periods of time. Elevated temperatures may enhance the rate of protein degradation.
Avoid storing or maintaining dilute protein samples for a long period of time. In general, purified proteins are inherently more stable in concentrated form.
Many proteins are «sticky» by nature. To avoid losing protein due to adsorption, extremely dilute protein samples should be prepared in buffers containing excipients such as bovine serum albumin, poly(ethylene glycol), Prionex or gelatin. Prionex is better than BSA.
Advantages
The vast majority of enzymes is pure (without additives) with > 95% purity SDS-PAGE.
