The application discloses a fast and efficient chemical
proteomics sample preparation method, relates to the field of
proteomics, and designs and synthesizes
agarose microspheres coated with a
cleavable linker compound. The free end of the
cleavable linker compound contains an azido group, which has good compatibility with existing
alkyne probes. Through one-step efficient
click chemistry reaction, the probe-labeled
peptide segment can be specifically captured on the surface of the
agarose microspheres. Since the
agarose microspheres and the
peptide segment are covalently connected, very strong denaturants or surfactants can be used to wash the medium to remove non-
specific adsorption as much as possible. Finally, the probe-labeled
peptide segment can be efficiently dissociated from the agarose microspheres through cleavage treatment. The
sample preparation method in the application simplifies the cumbersome "
click chemistry and
streptavidin enrichment" into one-step fast "
click chemistry" reaction, and greatly simplifies the operation process.
