• Overview:

  Recombinant bovine Trypsin lyophillized powder. The typical use for this product is the removing adherent cells from a culture surface. Trypsins have also been used for the re-suspension of cells during cell culture; Trypsin cleaves peptides on the C-terminal side of lysine and arginine residues, the optimal pH for trypsin activity is 7-9. We have directional protein refolding technology (LeaBioFOLD) and self-developed technology platforms for proteins covering screening and purification, engineering design, fixed-point coupling design, and dosage form development. Protein refolding is a process of recovering protein aggregates in inclusion bodies in the form of misfolded and inactive proteins expressed by prokaryotes such as Escherichia coli back into proteins with correct conformation and bioactivity under appropriate conditions in vitro. It is a key technology for biopharmaceutical companies but a major bottleneck in protein production in prokaryotic expression systems. Leading Biology has been specializing in protein refolding for many years, has a core team with over ten years of experience in this technology and rich experience in its industrialization. Our team is summarizing the experience to form an independent technological system of ours.
