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. WebThe S45A streptavidin mutant (SA-S45A), which displays a faster off-rate for biotin, was utilized with a bivalent biotin carrier that retains high avidity for the streptavidin mutant. Mice were fed either a normal or biotin-deficient diet, yielding serum endogenous biotin concentrations of 31 nM and 5 nM, respectively.
