Since the solid-phase peptide synthesis method was invented in 1963, it has been widely used in the research of biologically active peptides and protein functions, and the research and production of peptide drugs. The basis of the solid-phase synthesis method is the polymer material as the carrier. This material is generally 100-200 mesh or 200-400 …
Immobilized enzyme technology is to immobilize biological enzymes on a solid carrier for enzymatic reactions in solution. Compared with the free enzyme, the immobilized enzyme has the advantages of high stability, convenient recovery, easy separation from the reaction system, repeated use for many times, low cost, etc., and has a very broad development prospect. Nankai …
ES-1 is the earliest industrialized production and application of enzyme carrier in China. It is used to prepare 6-APA from Penicillin G, and its performance is similar to Sepabeads EC-EP. Picture 1.png The activity of penicillin acylase immobilized with ES-1 carrier is equivalent to that of foreign products, and the strength is obviously better than …
Hemoperfusion refers to the removal of endogenous or exogenous pathogenic substances in the blood through an adsorbent device with a broad-spectrum detoxification effect or fixed specific ligands through extracorporeal circulation to achieve the purpose of blood purification. Hemoperfusion is currently mainly limited to adsorption, so it is also called hemosorption. Hemoperfusion is often combined with …
