An antibody was prepared by immunizing rabbits with an ovalbumin conjugate
of 2-amino-2-(2-(4-(4-mercaptobutyl)phenyl)ethyl)propane- 1,3-diol HCl (AMP
D-4), which contains the essential structure of the novel immunosuppressant
FTY720. As the antibody reacted to not only AMPD-4, but also FTY720, it sh
ould be useful for immunoassay of FTY720 in body fluids, tissues and cells.
