Abstract:
Gel plugs that can be stored in a sealed condition and delivered individually to an electrophoresis gel as standards for electrophoretic separations are retained in a cartridge that is cleanly breakable into individual sections, each section retaining a gel plug of predefined dimensions with standard solute mixtures embedded in the plug. The separation of any single section from the cartridge exposes opposing edges of the gel plug which permits the user to insert an implement into the section interior and to urge the plug out of the section and into a well of an electrophoresis gel. All manipulations are performed without any need for contact between the user and the gel.
Abstract:
Electrotransfer is performed in an instrument that receives electroblotting cassettes and that contains an integrated power supply, controls, and a display that allows the user to monitor and control each of a plurality of cassettes individually through electrical contacts within the housing that mate with corresponding electrical contacts on the cassettes.

Abstract:
Molds for casting and retaining electrophoresis gel strips are provided, along with methods, kits, and systems for performing electrophoresis, electroelution, and/or electroblotting. A mold according to some embodiments includes: an array of elongated lane cavities, each lane cavity having a top end, a bottom end, and two or more sides, the lane cavities oriented parallel to each other; a matrix comprising at least one solid material and disposed along the sides of the lane cavities, the matrix separating the lane cavities from each other and from the space outside the mold; and a plurality of windows, wherein two windows are associated with each lane cavity and are disposed on opposite sides of the lane cavity, each window running lengthwise along the lane cavity and penetrating the matrix, thereby forming a passage from the lane cavity through the matrix to an adjacent lane cavity or the space outside the mold.
Abstract:
Systems and methods for simultaneously exciting a fluorescently labeled specimen and capturing fluorescent light emitted therefrom using a smartphone, tablet, or similar mobile computing device, are disclosed herein. The system includes a light-emitting diode ("LED") light source coupled with the smartphone to excite the specimen and an imaging device coupled with the smartphone to capture fluorescent light emitted from the specimen. The system further includes a hood adapted to be coupled with the smartphone that has an excitation filter configured to produce a first wavelength of electromagnetic radiation to strike the specimen when light from the LED light source passes through it and an emission filter configured to receive the light emitted from the specimen and to produce a second wavelength of electromagnetic radiation to be captured by the imaging device.
Abstract:
Molecular species that are immobilized in discrete locations on a planar support such as protein bands on a gel or a blotting membrane or species applied in dots or spots on a membrane are reacted with binding reagents that are applied through a porous hydrophilic transfer sheet placed over the planar support, the sheet having at least one region that is laterally bordered by a barrier with the binding reagent retained within the bordered region. The bordered region is placed directly over an area on the planar support where the molecular species are expected to reside if they are present on the support. The binding reagent is then delivered into the support to contact the species. Targeted delivery of the binding reagent is thus achieved with improved efficiency.
