Hi there . . .
I am looking for a method of separating hapten-labeled IgG, specifically, biotin labeled,
from unlabeled IgG. I am considering using an affinity column bound with anti-biotin.
It's simple to remove the unbound biotin from the reaction matrix . . . just use a good old
PD-10 (G25) column (Pharmacia). But, what about the unlabeled IgG. Size exclusion certainly won't work; biotin is only ~250 Da.
Would and affinity column work?
