Appl. No.:

13/457972

Inventors:

Gary William Dombrowski - West Chester PA, US
Zhenwen Fu - Lansdale PA, US
Caroline Slone - Ambler PA, US
Andrew Swartz - Fleetwood PA, US

International Classification:

B05D 3/02
C09D 163/02
C09D 163/04
C09D 163/00

US Classification:

427386, 523412, 523403

Abstract:

The present invention relates to a stable aqueous dispersion of thermoplastic polymer particles imbibed with a thermosettable compound. The polymer particles are characterized by having a sufficient concentration of anti-agglomerating functional groups to stabilize the latex against agglomeration. The dispersion is useful as one part of a two-pack formulation.

Abstract:

The present invention provides a nanoparticle capable of binding specifically to a target protein in a solution and precipitating with the target protein out of the solution upon addition of the target protein to the solution. The precipitation may be reversed release the target protein from the nanoparticle, which may be reused for precipitating the target protein. Also provided are a method for purifying a target protein by affinity precipitation using the nanoparticle without chromatography and a method for preparing the nanoparticle.
