Abstract
The present disclosure relates to methods and products associated with in vitro and in vivo protease activity measurements and enzyme profiling. Some aspects of the present disclosure relate to measuring remotely triggered protease activity. In particular, the disclosure relates to methods of in vivo processing of exogenous molecules followed by detection of signature molecules as representative of the presence or absence of active enzymes associated with disease or conditions. The disclosure also relates to products, kits, and databases for use in the methods of the disclosure.
Claims9
A composition comprising:
- a biomarker particle, wherein the biomarker particle comprises a carrier domain linked to a detectable marker via an enzyme substrate, wherein:
- (a) a photolabile protecting group is positioned at a residue adjacent to an enzyme-target scissile bond in the enzyme substrate;
- and/or
- (b) a liposome encapsulates the carrier domain linked to the detectable marker via the enzyme substrate, wherein the liposome is a thermosensitive liposome, a liposome comprising gold nanoparticles, a pH-responsive liposome, or a reactive oxygen-responsive liposome.
