WebJun 30, 2024 · The Streptavidin-biotin complex is generally stable over a wide pH ranges. However, the formation of the complex is disrupted only by conditions that lead to irreversible denaturation of the proteins. 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.
WebAgarose beads and affinity gels. Agarose beads and affinity gels enable biotinylated protein and biotinylated antibody purification using streptavidin or avidin cross-linked to beaded agarose. Both avidin and streptavidin bind to biotin with high affinity, though avidin can exhibit high non-specific binding.
