PolyQuant’s EcoCAT Kit provides 100 reference peptides for absolute protein quantification of 48 common and critical E. coli-specific host cell proteins (HCP). The peptides are grouped onto two individual, completely 15N labelled, QconCAT proteins.

QconCAT technology is compatible with various sample preparation protocols (e. g. in-solution, FASP, SP3) and different machine methods (e.g. DIA/SWATH, PRM/MRM, SureQuant) and enables easy setup of multiprotein methods.​
