I'm using an immobilised phosphopeptide (containing phosphoserine) to
affinity-purify a binding protein - the binding stage works fine, and is
phosphoserine-dependent, since the nonphosphorylated peptide does not bind.
Can anyone suggest a method to elute the (native) binding protein, perhaps
something based on 'competition' using a phosphate buffer?
Many thanks in advance
