Abstract: A method and system for the graphical formulation of filter queries is disclosed which enables data queries to be easily via selection from a menu. A signal is received to filter, or query, a data table. Next, the context of the signaled key field is analyzed, and a menu of filters based on that context is formulated and displayed. A filter selection is received, and the corresponding filter is executed. The results of the filter are displayed on the screen.

Abstract: A polyanionic polymer can improve the bioactivity and water-solubility properties of a drug to which it is joined. The inventive method provides a monodispersed preparation of a recombinantly-produced polyanionic polymer that can be easily manipulated, such as lengthened. An active moiety may be chemically or recombinantly joined to a polyanionic polymer to increase its biological half-life and/or solubility. The instant invention also provides a method for targeting the delivery of a polyanionic polymer conjugate or fusion protein to a specific cell type or tissue.
