Abstract: Method and reagent composition for covalent attachment of target molecules, such as nucleic acids, onto the surface of a substrate. The reagent composition includes epoxide groups capable of covalently binding to the target molecule. Optionally, the composition can contain photoreactive groups for use in attaching the reagent composition to the surface. The reagent composition can be used to provide activated slides for use in preparing microarrays of nucleic acids.

Abstract: The invention provides controlled release compositions for treatment of parasitic mites in honeybees, the compositions composed of a covalently crosslinked polymer gel and an active agent that includes a salt of formic acid. The invention also provides methods for controlling parasitic mites in honeybees, the methods involving treating the honeybees with a controlled release composition composed a covalently crosslinked polymer gel and an active agent that includes a salt of formic acid. The invention further provides a kit for treatment of parasitic mites in honeybees, the kit including an envelope that contains a controlled release composition of the invention. Optionally, the active agent can include formic acid.
