Streptavidin is purified from the bacterium Streptomyces avidinii. It is a tetrameric protein with a molecular weight of approximately 53kDa. Each of the four identical subunits will bind one biotin molecule with a very high degree of specificity and affinity (Kd = 10-15M).
Fluorescein is a synthetic organic fluorophore, with an excitation wavelength of 494nm and a maximal emission wavelength of 520nm.
