一般描述
Avidin is a homotetrameric glycoprotein found in the egg white of birds, reptiles and amphibians. Each subunit is 16 kDa, singly glycosylated and binds to a molecule of biotin with greater affinity and specificity. Recombinant avidin from corn is similar to avidin from egg white in terms of properties like isoelectric point (pI) and antigenic properties. Avidin from corn has low molecular weight than chicken egg-derived avidin. Commercial production of avidin from corn has certain advantages in terms of availability of greater biomass and avoiding the co-purification of animal virus.

应用
Anti-Avidin antibody produced in rabbit has been used in enzyme-linked immunosorbent assay (ELISA). It has also been used in preparation of antibody-Au nanoparticles.
The presence of Scavidin in BT4C glioma cells was assessed by western blot using a rabbit anti-avidin antibody as the primary at a dilution of 1:4000. Lehtolainen, P. (2002) Cloning and Characterization of Scavidin, a Fusion Protein for the Targeted Delivery of Biotinylated Molecules. J. Biol. Chem. 277:8545-8550.
生化/生理作用
Avidin binds strongly to biotin. Thus, avidin-biotin association has been utilized in immunoassays to detect the localization of antigens in tissues. The use of avidin-biotin immunoassay enhances the sensitivity of the technique and facilitates the detection of antigens in low quantities.
