    摘要: The invention provides criteria and methods for selecting optimum subsequence(s) from a target gene for targeting by a zinc finger protein. Some of the methods of target site selection seek to identify one or more target segments having a DNA motif containing one or more so-called D-able subsites having the sequence 5′NNGK3′. Other methods of the invention are directed to selection of target segments within target genes using a correspondence regime between different triplets of three bases and the three possible positions of a triplet within a nine-base site. In another aspect, the invention provides methods of designing zinc finger proteins that bind to a preselected target site. These methods can be used following the preselection of target sites according to the procedures and criteria described above. The methods of design use a database containing information about previously characterized zinc finger proteins.

    摘要: Methods are provided using high pressure to treat aggregated interferons, to reduce the aggregate content of interferon material. In particular, recombinant human interferon-β may be so treated. Multiple strategies may be used in combination to make nonglycosylated IFN-β more amenable to high pressure treatment. When coupled with purification techniques, these strategies singly or in combination provide a low aggregate or substantially aggregate free, biologically active solution. In certain aspects, pharmaceutical compositions containing nonglycosylated interferon having less than about 5 weight percent of protein aggregation are provided.
