PolyQuant’s CHOcoCAT Kit provides 86 reference peptides for absolute protein quantification of 29 common and critical CHO-specific host cell proteins (HCP). The peptides are grouped according to abundance in CHO cells 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.​
