Maxygen is still around (as a private company): https://www.prnewswire.com/news-releases/maxygen-relaunches-in-sunnyvale-to-offer-well-established-molecular-breeding-technology-with-new-collaborative-vision-300601147.html Maxygen is pleased to announce the availability of the molecular breeding directed evolution platform to the biotechnology industry on a fee-for-service basis. This approach to improving protein function has broad applicability with particular relevance to the fields of synthetic biology, metabolic engineering, gene therapy, immunotherapy, and gene editing. I thought this technology (such as it is) was owned by CDXS (a spinoff of the original Maxygen) based on the deal announced in 2010 (#msg-56059056).
