pseudovitamin b12

[Jeff Lawrence]

i am looking for any commercial source of cobamides that do not have
5,6-DMB as the lower ligand.  pseudo-vitamin B12 (adenine down there),
Factor iii (with 5-hydroxy-DMB) or any other compound would do.  any
pointers would be greatly appreciated.  please post or e-mail info.  thanx
