Questions about Enzymes & substrates

What does activity in U/mg tell me about an enzyme?

One unit (U) is the amount of enzyme that converts a set amount of substrate per minute under defined conditions, such as temperature, pH and substrate. Units per milligram give the specific activity, which also says something about purity. Only compare values that use the same unit definition and assay conditions; the product page and certificate state both. Browse the range in enzymes and substrates. Questions about a specific product? Contact sales@luminixhealth.com.

How do I store and dissolve an enzyme?

Store the lyophilisate dry and cold, at the temperature on the label. Dissolve it in the recommended buffer and mix gently by swirling or inverting; vigorous shaking can denature the protein. Then divide the solution into portions and freeze them, so you avoid repeated thawing and loss of activity. Label each portion with the date and concentration. Suitable buffers are in biological buffers. Unsure which one fits? Ask sales@luminixhealth.com.

Why Enzymes & substrates?

An enzyme is sold by activity, in units defined by a stated reaction, not only by milligrams. Source and specific activity are the specification. A substrate is the molecule that enzyme converts, often a chromogenic one so the reaction can be seen. Units from two suppliers are comparable only when the definition matches.

A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
