Abstract: Systems and methods are disclosed for presenting images of multiple, variant user interfaces along with corresponding metrics for concurrent comparison by a user. Client interfaces allow a client to interact with an underlying system and/or application. Examples of client interfaces include webpages that are presented to a client in a client/server system. Embodiments of the disclosed system and method allows user interface designers to directly compare images of variants of a user interface and corresponding metrics with images of one or more other variants on a display. In at least one embodiment, an image of a variant and corresponding metrics are designated as a control against which images of other variants and corresponding metrics are directly compared on the display.

Abstract: The present invention relates to a two-step method for isolating proteins from the cystine-knot superfamily based on dye ligand affinity chromatography and reversed-phase chromatography. Advantageously, the method can be performed in a relatively short period of time, involves inexpensive reagents, and requires little sample preparation before and during the purification process. Protein fusions between cystine-knot proteins and proteins of interest are further provided for the isolation of said protein of interest or complexes containing said protein of interest using the two-step method disclosed.
