Streptavidin is a biotin binding protein that is widely used in molecular biology due to its extremely high affinity with the small molecule biotin. Streptavidin can be conjugated with a wide variety of fluorophores and enzymes for use in molecular biology experiments. Streptavidin is a preferred replacement for avidin due to its higher specificty and lower levels of non-specific interactions.
