Abstract:
Methods for detecting one or more analytes, such as a protein, in a fluid path are provided. The methods include resolving, immobilizing and detecting one or more analytes in a fluid path, such as a capillary. Also included are devices and kits for performing such assays.
Abstract:
In general, the present invention provides microfluidic devices comprised of polymer coatings with triggerable analyte capture moieties. In some embodiments, a microfluidic device is provided, useful in electrophoresis, and is comprised of at least one separation channel with a surface, such as but not necessarily an inner surface, and having a polymer coating introduced onto the surface. The polymer coating is comprised of moieties capable of being triggered to immobilize analytes to the surface.

Abstract:
An automated assay system is described with stations for placement of materials to be used in an assay of materials inside capillaries and an automated gripper for manipulating capillaries. The system includes a separation and immobilization station where reactions inside the capillaries take place and a detector station where photoemissions from the capillary reactions are detected. The photoemissions from the capillaries may be displayed as line graphs or in columns of a pseudo-gel image resembling the familiar Western gel blot. An automated control system has a user interface by which an operator can select a run protocol and define the locations of samples and reagents to be used in the protocol run. Following the setup the control system will cause the automated system to execute the protocol, then display the results in a selected display format.
Abstract:
A method is disclosed for protecting a harvested crop from pathogens comprising applying to the harvested crop and to any pathogen present thereon a compound capable of generating an active oligomer elicitor in the crop or the pathogen. The compound is applied with a penetrating agent which aids in the entry of the compound into the cuticle layer of the harvested crop or the pathogen. The elicitor is generated in the crop or the pathogen in an amount effective to elicit production in the crop of an anti-pathogenic agent. When the elicitor is generated in a pathogen present on the harvested crop, the elicitor is generated in sufficient amount to transfer into the crop, which transfer may be aided by the presence of said penetrating agent, in order to produce the desired phytoalexins in the harvested crop. Also disclosed is a composition comprising the above compound and a penetrating agent for the compound as well as a harvested crop treated with the above composition.
Abstract:
Methods for detecting one or more analytes, such as a protein, in a fluid path are provided. The methods include resolving said analytes in a fluid path based on the size of said one or more analytes, immobilizing and detecting said analytes. The methods also include resolving, immobilizing said analytes in the fluid path by heating the fluid path and detecting said analytes. Preferably, the fluid path is a capillary. Devices and kits for performing such assays are included as well.
