How many biotin binding-sites are there per streptavidin molecule?

Streptavidin is a protein composed of four identical subunits, each containing a high affinity binding site for biotin (K-D = 10 -15 M) . Streptavidin has the same biotin binding properties as avidin, but it has a low isoelectric point (pI=5) and no carbohydrate groups, resulting in low non-specific binding.

What is the binding capacity of streptavidin agarose?

The binding capacity of streptavidin agarose is 15-20 µg (18-24 nmoles) of fluorescein biotin per mL of sedimented gel.
