Avidin. The extraordinary affinity of avidin for biotin allows biotin-containing molecules in a complex mixture to be specifically bound to avidin. Avidin is a glycoprotein found in the egg white and tissues of birds, reptiles and amphibia.It contains four identical subunits having a combined mass of 67 to 68kDa.n contrast to avidin, though, streptavidin is not glycosylated, which makes the protein less-prone to nonspecific binding in IHC applications. Pierce products use a recombinant form of streptavidin, having a mass of 53kDa and a near-neutral pI.
