  • Patent number: 9052323
    Abstract: An osmolyte composition comprising 4 M glycerol and 4M urea for stabilizing previously transient protein folding intermediates as long-lived stable forms. A method to search for other possible stabilizing osmolyte mixtures using a screening array is also provided. These additional osmolyte mixtures may complement or augment the successful 4M glycerol/4 M urea mixture.
    Type: Grant
