Description: | Avidin is a protein derived from both avians and amphibians that shows considerable affinity for biotin, a co-factor that plays a role in multiple eukaryotic biological processes. Avidin and other biotin-binding proteins, including Streptavidin and NeutrAvidin protein, have the ability to bind up to four biotin molecules. <br>The bond formation between biotin and Avidin is very rapid, and once formed, is unaffected by extremes of pH, temperature, organic solvents and other denaturing agents. |
