    Abstract: An acrylamide gel formulation for use in electrophoresis, and a system and method for electrophoretic gel casting. In some embodiments, the system comprises a UV-Vis curing light source, and an acrylamide formulation that allows a resolving gel and a stacking gel to be photopolymerized in a single step. In some embodiments, the resolving solution formulation comprises acrylamide and bis-acrylamide, Bis-Tris buffering agent, and lithium phenyl-2, 4, 6-trimethylbenzoyl-phosphinate (LAP) as a water-soluble photoinitiator, which allows the solution to be photopolymerized using UV radiation within a certain wavelength. In some embodiments, a dilution buffer formulation comprises acrylamide and bis-acrylamide, Bis-Tris buffering agent, and lithium phenyl-2, 4, 6-trimethyl-benzoyl-phosphinate (LAP). The dilution buffer may be added to the resolving solution in a selected amount in order to modify the concentration of the acrylamide to a desired concentration.

    Abstract: Port protection device particularly suited for an encapsulated filter unit. In certain embodiments, the protection device comprises a main body defining an internal region configured to receive a port or the like protruding from an encapsulated filter. In certain embodiments, the main body includes a slot that allows for easy removal of the protection device from the port or the like. A tube management system may be provided to receive and hold tubing. One suitable tube management system includes two spaced tangs that extend from the main body of the protection device and are configured to cooperatively receive and hold tubing between them.

    Abstract: A fluid filtration device containing a composite filter media having a coarse porous polymeric nonwoven interlayer located between first and second polymeric fiber containing filter mats. The fiber diameters of the fibers in the first and second filter mats are different from each other, and each filter mat has a different pore size rating. The first and second polymeric fibers in the filter mats can be electrospun nanofibers. The interlayer has a coarser pore size when compared to the either the first or second filter mats, such that the resulting composite media has an increased dirt holding capacity compared to filter layers that are layered directly over each other without the presence of a coarse interlayer therebetween.
