Biotin-binding plates: Streptavidin or neutravidin: Binds small biotinylated peptides and other small molecules that are difficult to bind by passive adsorption: WebDec 2, 2024 · Recently, proximity based biotin identification (BioID) has emerged as an alternative approach to traditional co-immunoprecipitation. In this protocol, a mutant biotin ligase promiscuously labels proximal binding partners with biotin, and resulting biotinylated proteins are purified using streptavidin conjugated beads.

WebBiotin is commonly used because it binds to avidin or streptavidin with high affinity (Kd=10-15 M), the strongest of any non-covalent bond.1 This affinity constant is significantly higher than that between DIG and an anti-DIG monoclonal antibody, and contributes to the higher reproducibility of the biotin/streptavidin system.
