Streptavidin acrylamide is a reagent used in biochemical assays and molecular biology techniques. It consists of streptavidin, a protein with a high affinity for biotin, conjugated to acrylamide. This reagent is used for immobilizing biotinylated molecules onto a solid support, such as a gel matrix, for applications like affinity purification and western blotting., Its high binding affinity and specificity make it a versatile tool for a wide range of applications.
