DIGESTIF is a universal protein standard to assess
simultaneously the quality of sample workup
& the performance of your LC-MS system

What is DIGESTIF ?

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.

Why use DIGESTIF ?

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.
