Digestif
- Digestif comprises a soluble recombinant protein scaffold + 11 artificial peptides (iRT) with good ionization.
- Amino acids flanking iRT cleavage site either favour or hinder protease cleavage.
- Retention time & relative intensity pattern of released iRT can assess the quality of sample workup, the extent of digestion, LC-MS performance & inter/intra-lab variability
