In response to the industry's demand for hig volumes of gentamicin sulfate, Sunresin developed an optimal process, based on LX series resins, for the purification of gentamicin sulfate and other aminoglycoside pharmaceuticals thanks to the great know how of the team of R&D and production experts.

The new Sunresin Seplife®Oligo dT affinity resin is designed for the purification and isolation of mRNA from in vitro transcription (IVT) manufacturing processes. Using the 20 years experience of Sunresin in manufacturing specialty resins, we have designed a unique technology that manufactures a 50 micron polymeric resin with very uniform particle sizes by seed swelling. The resin is a crosslinked polystyrene divinylbenzene resin functionalized with oligo dT20. The resin effectively captures mRNA from components of the transcription reaction process, such as enzymes and plasmid DNA.

1. Cephalosporin C Also known as CPC (cephalosporin C, M = 415.44), it is an antibiotic produced by a fungus of the genus Cephalospores close to penicillin. Cephalosporin C is a raw material for the production of 7-aminocephalosporanoic acid (7-ACA, 7-aminocephalospranic acid, M=272.28), and 7-ACA is an important raw material for many synthetic cephalosporin antibiotics.

1. Vitamin B12 Known as cobalamin. It is a water-soluble vitamin that participates in various metabolisms in the form of coenzymes and promotes DNA and protein synthesis. 2. Synthesis of vitamin B12 The chemical synthesis of vitamin B12 is costly and the by-products are also more. At present, the mainstream is the fermentation method.
