We've been screening streptavidin and deglycosylated avidin
(unlabeled) preparations from a number of suppliers and to
our dismay, we've found them quite heterogeneous when
analyzed on gel filtration columns.  Does anyone have a
favorite supplier of high quality and homogeneous streptavidin
(or deglycosylated avidin)?  I'm only interested if you 
happen to know that the material is in good shape.

Thanks,
