Abstract
The present invention provides imprint compositions useful for capturing, isolating, detecting and/or quantifying macromolecules in a sample, methods of making and using the same. Generally, the imprint compositions comprise a matrix material defining an imprint of a template molecule, and the template molecule typically corresponds to a portion of a macromolecule of interest.

33. A method of making an imprint composition capable of capturing a macromolecule of interest, comprising the steps of:
-
(a) solidifying a fluidic matrix material capable of retaining shaped cavities when in a solid or semis-solid form in the presence of a template molecule that corresponds to a portion of the macromolecule, thereby yielding a solid or semi-solid matrix material having template molecules entrapped therein; and
(b) removing the template molecules from the solid or sem-solid matrix material, yielding an imprint composition capable of capturing the macromolecule. - View Dependent Claims (34, 35, 36, 37, 38)

41. A method of capturing a plurality of macromolecules, comprising contacting the plurality of macromolecules with a spatially identifiable array of imprint cavities, wherein each imprint cavity is of a template molecule that corresponds to a portion of one of the macromolecules of the plurality, under conditions in which the macromolecules bind their corresponding imprint cavities.

42. A method of quantifying the relative amounts of a plurality of different macromolecules in a sample, comprising the steps of:
-
(a) contacting the sample with a spatially identifiable array of imprint cavities, wherein each imprint cavity is of a template molecule that corresponds to a portion of one of the macromolecules of the plurality, under conditions in which the macromolecules bind their corresponding imprint cavities; and
(b) quantifying the amount of macromolecule bound to at least a subset of the plurality of imprints.

43. A method of making a spatially-identifiable array of imprint cavities, comprising the steps of:
-
(a) solidifying a fluidic matrix material capable of retaining shaped cavities when in a solid or semis-solid form in the presence of a spatially-identifiable array of immobilized template molecules, thereby yielding a solid or semi-solid matrix material having template molecules entrapped therein; and
(b) removing the template molecules from the solid or sem-solid matrix material, yielding a spatially-identifiable array of imprint cavities. - View Dependent Claims (44, 45, 46, 47)
