摘要:
The present invention relates to a bioreactive agent comprising a detectable moiety linked to a photo-reactive moiety, wherein said photoreactive moiety comprises at least one group covalently bound to a substrate to form a conjugate that can be selectively photocleaved to release said substrate, wherein said substrate is selected from proteins, peptides, amino acids, lipids, cells, virus particles, fatty acids, nucleic acids, nucleotides, nucleosides, oligonucleotides, polysaccharides and inorganic molecules.
