  • Compounds and Methods for FRET Based Measurement of Enzyme Activity
    Publication number: 20130078661
    Abstract: Provided are compositions and methods for Fluorescence/Forster Resonance Energy Transfer (FRET) analysis of cleavage of Von Willebrand Factor (VWF) polypeptides by the metalloprotease ADAMTS13. The polypeptides contain: i) a first fluorescent protein ii) a VWF amino acid sequence and iii) a second fluorescent protein. The VWF amino acid can contain any of a variety of amino acid substitutions. The method involves contacting a sample that contains ADAMTS13 and using FRET based measurements to determine ADAMTS13 cleavage of the recombinant polypeptide.

  • Recovery of liquids from absorbent packaging materials
    Patent number: 7008797
    Abstract: The present invention describes a method for recovery of aqueous samples or components thereof from polymer packaging materials, wherein the spilled aqueous sample has been absorbed by the packaging material to form a liquid swollen absorbent gel. The method comprises the steps of contacting the liquid swollen absorbent gel with a recovery fluid, wherein the recovery fluid has a higher osmotic pressure than the aqueous sample.

  • Recovery of liquids from absorbent packaging materials
    Patent number: 6589797
    Abstract: The present method describes a method for recovery of aqueous samples or components thereof from polymer packaging materials, wherein the spilled aqueous sample has been absorbed by the packaging material to form a liquid swollen absorbent gel. The method comprises the steps of contacting the liquid swollen absorbent gel with a recover fluid, wherein the recovery fluid has a higher osmotic pressure then the aqueous sample, disrupting the gel and removing the recovery mixture for detection and analysis of analyte.
