cQrex® AY (L-Alanyl-L-tyrosine trihydrate) is a chemically defined and non-animal-derived peptide designed to overcome the solubility challenge associated with L-tyrosine in cell culture media.
As an alanine-based alternative to cQrex® GY (Glycyl-L-tyrosine dihydrate), cQrex® AY enables the formulation of basal, feed and perfusion media at neutral pH. It helps to intensify and simplify the bioprocess for a highly efficient production of biopharmaceuticals like monoclonal antibodies.
