DEVELOPMENT AND USE OF FLUORESCENT PROBES OF UNBOUND BILIRUBIN

摘要

Identification and use of proteins fluorescently labeled and that undergo a change in fluorescence index upon binding bilirubin are described. Probes are disclosed which are labeled at a cysteine or lysine residue and also probes labeled at both cysteine and lysine with two different fluorophores. These probes are useful for determination of unbound bilirubin levels in a fluid sample.
