Abstract:
A solid substrate for the extraction, stabilization, and storage of proteins is provided. The substrate includes: a polysaccharide, such as melezitose under a substantially dry state. The substrate is configured to extract proteins from a sample and stabilize the extracted proteins in a dry format under ambient conditions for a prolonged period of time. Methods for collecting and recovering the proteins stored in the dry solid substrate are also described.
Abstract:
A device comprising a modified porous membrane is provided. The modified porous membrane comprises a polymer coating grafted to a porous membrane. The device is used for analyte detection from a biological sample using an immunoassay. The device comprises a sample application zone at one end of the device for applying a biological sample comprising a target analyte; and a detection zone present at another end of the device, downstream of the sample application zone for detecting the target analyte, wherein the detection zone comprises one or more first biomolecules immobilized on a modified porous membrane having a structure of Formula (I).

Abstract:
A modified porous membrane comprising a polymer coating grafted to a porous membrane is described. A method for analyte detection from a biological sample using an immunoassay is also provided using the modified membrane, wherein the method comprises a) providing a modified porous membrane having the structure of Formula (I), b) incubating the modified porous membrane with a first biomolecule, wherein the first biomolecule binds to the modified porous membrane to form a first biomolecule bound modified porous membrane; and c) adding a biological sample comprising at least an analyte to the first biomolecule bound modified porous membrane for analyte detection by binding the analyte to the first biomolecule bound to the modified porous membrane.
