摘要:
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.

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.
