Fluorescence polarization assay for cyclosporin A and metabolites and related immunogens and antibodies

摘要

The present invention is directed to a fluorescence polarization immunoassay for cyclosporin A and metabolites thereof. The present invention also relates to novel cyclosporin A derivative compounds useful in fluorescence polarization techniques. Included among the novel compounds are cyclosporin A derivatives where the amino acid in the first position is altered. The cyclosporin A derivatives are useful in forming immunogens for raising antibodies specific to cyclosporin A and metabolites thereof.
