cross-linking

I've had some experience with cross-linkers.  THE best place for X-linkers,
IMHO, is Pierce Chemical Co.  They stock a large selection of them.  I'm
partial to DTSSP as it is cleavable with 2-ME, DTT, and has a rather long
reach of 11 Angstroms, if I'm not mistaken.  It's also water soluable.
I believe that you will find what you need in the Pierce Catalog.
