Cyanocobalamin acid hydrazides and their conjugates |
| abstract |
The present invention provides cobalamin acid hydrazides of the general formula: n n B--CO--NH--NH--R--CO--NH--NH).sub.x H (I) n n wherein B is a residue formed from a cobalamin by the splitting off of a --CONH 2 group, R is a spacer and x is 0 or 1, as well as a process for the preparation thereof. n The present invention also provides cobalamin conjugates of the general formula: n n B--d--CO--NH--NH--R--CO--NH).sub.x N═GP (II) n n in which B, R and x have the above-given meanings and d signifies the position of --CO--NH--, as well as a process for the preparation thereof. These cobalamin conjugates are very suitable for use in immunoassays, especially for the determination of cyanocobalamin. |
