AmProtein is a biotech company founded in 2002 by Matthew Hui, MD, PhD, formerly a protein production scientist at Amgen. AmProtein has discovered a novel, non-sparging dissolved oxygen generating method and a DNA physical structure-based gene expression mechanism.
Based on the above non-sparging O2 transfer method, we have successfully commercialized a single-use, plastic bag-based bioreactor series as an effective dissolved oxygen (DO) generator for high-density suspension cell culture. In addition, AmProtein has successfully developed a high-density perfusion cell culture system by using a single-use, cell attachment paper-carrier material and our suspension culture system as a DO generator.
AmProtein has established facilities (www.amprotein-china.com) in China, which manufacture single-use bioreactors and produce tissue-targeted Enbrel and other two-domain drugs.
