CQREX™ SAMPLE KIT
Are you interested in our products and would like to order a sample kit of cQrex™ cell culture ingredients?
It allows you to test our substances in your system, as no cell line is quite the same.
A combination of our current line-up of boosters is gathered in one kit. You are looking for something else besides our standard amino acids? Individual samples can be supplied upon request.
Chemically defined boosters
GMP grade peptides and keto acids solving key issues in mammalian cell culture.
Dipeptides for solubility
cQrex™ GY, a L-Tyrosine containing peptide, offers high solubility at neutral pH without introducing new substances to the medium and is readily metabolized.
Dipeptides for stability
cQrex™, cQrex™ AQ and GQ stabilize the amino acid, leading to longer shelf life and improved cultivation performance.
Keto-acids for performance
cQrex™ AKG directly stimulates the energy cycle without ammonia generation and acts as scavenger for ammonia and oxidants, boosting cell density and titer levels.
