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