In our endeavour to be a comprehensive solutions provider in the biopharma process solutions space, Signet has partnered with Evonik to offer their innovative cQrex® peptide range and Phytochol® Biopharma products.
Evonik continues to push the boundaries of upstream processing technology with its cQrex® portfolio, designed to enhance operational efficiency and product quality. These solutions address critical solubility and stability challenges associated with amino acids such as L-Glutamine, L-Cysteine and L-Tyrosine in mammalian cell cultures. By chemically coupling amino acids with carrier amino acids, Evonik’s cQrex® products improve solubility, stability, and overall process throughput. The portfolio includes cQrex® AKG (alpha-Ketoglutaric acid) — a key Krebs cycle intermediate that helps protect cells from oxidative stress and boosts titres in biopharma cultures.
Evonik also offers Phytochol® Biopharma (Cholesterol USP/NF, EP) which provides a synthetic cholesterol alternative designed specifically for cell culture applications, eliminating the regulatory challenges of traditional sheep wool–derived cholesterol.
