DIGESTIF is a soluble recombinant protein scaffold (PBP2x, Penicillin-binding protein 2x from Streptococcus pneumoniae) deleted of its N-ter part and resulting from the collaboration between Biognosys, Promise Proteomics and academic teams1.
DIGESTIF is composed of 11 artificial peptides (iRT) of various hydrophobicity with good ionization.
DIGESTIF is a two-in-one quality control reagent used to check digestion quality & efficiency as well as LC-MS performances during bottom-up proteomic experiments.
