WebChromophore-assisted laser inactivation of protein function has been achieved. After a protein binds a specific ligand or antibody conjugated with malachite green (C.I. 42,000), it is selectively inactivated by laser irradiation at a wavelength of light absorbed by the dye but not significantly absorbed by cellular components. WebMar 1, 2002 · Chromophore‐assisted laser inactivation (CALI) provides a timely and locally restricted protein inactivation and has proven to specifically destroy protein function using dye‐coupled ligands and laser irradiation. CALI involves the generation of short‐lived radicals thus limiting the radius of covalent modifications to spatially ...
WebAbstract. Differential protein regulation is a critical biological process that regulates cellular activity and controls cell fate determination. It is especially important during early embryogenesis when post-transcriptional events predominate differential fate specification in many organisms. Light-induced approaches have been a powerful ... Webnotype. Chromophore-assisted laser inactivation using mal-achite green (MG)-tagged antibodies makes it possible to inactivate target proteins in a highly restricted manner, probing their temporally and spatially resolved functions. In this report, we describe the isolation and in vitro character-ization of a MG-binding RNA motif that may enable ...
