cQrex® AY (L-Alanyl-L-Tyrosine dihydrate) is a tyrosine peptide designed to overcome the solubility challenge associated with free L-tyrosine in cell culture media.
As an alanine-based alternative to cQrex® GY (Glycyl-L-Tyrosine dihydrate), cQrex® AY is a highly soluble, chemically defined and non-animal-derived ingredient which enables the formulation of concentrated and pH-neutral media.
cQrex® AY helps to intensify and simplify the bioprocess for a highly efficient production of biopharmaceuticals like therapeutic proteins or viral vectors.
