A reagent is defined as a substance or compound that is added to a system in order to bring about a chemical reaction or added to see if a reaction occurs. It is often likened to a reactant, however, a reagent is not consumed during the chemical reaction. A bioreagent is a reagent that has a biological origin. Enzymes are an example of a bioreagent.
Bioreagent Buffer Solutions
A buffer solution is an aqueous solution consisting of a mixture of either a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer’s pH changes very little when a small amount of strong acid or base is added to it. Because of this lab buffers are used to prevent changes in the pH of a solution and can keep pH at a nearly constant value in a wide variety of chemical applications. Many bioreagents such as enzymes work only under very precise conditions; if the pH moves outside of a narrow range, the enzymes slow or stop working and can denature. In many cases, denaturation can permanently disable their catalytic activity. Many organisms require a buffer solution to keep the correct pH for enzymes so they will continue to work. The hundreds of reagents and bioreagent buffer solutions here at ARP are used for a wide range of biological reactions. We look forward to providing research institutions and biotechnology customers with the highest quality of reagents, buffers and research laboratory supplies.
