Lys-C/Arg-C, a More Specific and Efficient Digestion Approach for Proteomics Studies Anal. Chem.,2018,90, 9700, DOI: 10.1021/acs.analchem.8b02448
The automated Iin situ endoproteinase Lys-C digestion of glutamine synthetaseHewlett, Packard
Matched pairs of fragmentation spectra with equal precursor mass and similar retention times from each digestion are compared, leveraging single-residue transposed information with independent interferences to confidently identify fragment ion type, residues, and peptides. The paired spectra are solved ...
Lysyl endopeptidase is an enzyme that hydrolyzes lysyl peptide bonds of nonterminal amino acids. It is highly specific and preferentially cleaves Lys-I-Xaa bonds, including Lys-I-Pro. Used in research as a standard laboratory reagent for enzyme digestion. This is useful to study the primary stru...
For peptide or protein digestion, a ratio between 1/20 and 1/100 (w/w) of enzyme to substrate is recommended.1.Dissolve the peptide or protein to be digested in 100 mM NH 4HCO 3, pH 8.5, or 100 mM Tris HCl, pH 8.5.2.Recommended incubation time is between 2 and 18 hours at ...

Enhancing Trypsin Digestion with Lys-C and Arg-C Proteases Scientific PosterMichael Ford
Endoproteinase lysine-C (Lys-C)/trypsin sequential digestion and trypsin digestion were used in 293T cell proteomics sample preparation and the differences of Lys-C/trypsin sequential digestion and trypsin digestion in proteomics sample preparation were systematically evaluated. It was found that the ...
