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.

WebStreptavidin lacks the carbohydrate side chains present on avidin and has an isoelectric point nearer to neutrality (pI of 5.5-6.5 versus 10 for avidin). Consequently, streptavidin frequently exhibits lower levels of non-specific binding than avidin. The extinction coefficient of a 1% solution at 280 nm is 32. WebStreptavidin is also a tetrameric protein, with each subunit binding one molecule of biotin with affinity similar to that of avidin. However, streptavidin is much less soluble in water than avidin. Guanidinium chloride at pH 1.5 will dissociate avidin and streptavidin into subunits, but streptavidin is more resistant to dissociation.
