>>Usually an equal molar ratio of biotin to protein works well when using

hydroxyusuccinimide ester).  If you find that you are getting high

with dig-NHS.  The anti-dig Fab conjugates do not stick non-specifically
and result in low background.<<

What is the [dig] in [dig-NHS]?  I am always looking for ways to reduce
background.  Much obliged.
