34 results about "Ion transporter" patented technology

In biology, an ion transporter (or ion pump) is a transmembrane protein that moves ions across a biological membrane against their concentration gradient through active transport. These primary transporters are enzymes that convert energy from various sources—including adenosine triphosphate (ATP), sunlight, and other redox reactions—to potential energy stored in an electrochemical gradient. This potential energy is then used by secondary transporters, including ion carriers and ion channels, to drive vital cellular processes, such as ATP synthesis.

Engineering absorption of therapeutic compounds via colonic transporters

InactiveUS20030158254A1BiocideAntimycoticsChemical MoietyMonocarboxylate transporter 1
Methods of modifying therapeutic compounds such as drugs to be substrates for active transporters expressed in epithelial cells lining the lumen of the human colon are disclosed. The transporters expressed in the human colon include the sodium dependent multi-vitamin transporter (SMVT), and monocarboxylate transporters 1 and 4 (MCT 1 and MCT 4). The modified compounds can themselves be pharmacologically active, or upon cleavage of a chemical moiety after uptake from the colon, can be metabolized to form a compound that is pharmacologically active (e.g., a prodrug). The modified compounds disclosed herein are suitable for use in extended release oral dosage forms, particularly those that release drug over periods of greater than about 2-4 hours following administration.

Unique battery with an active membrane separator having uniform physico-chemically functionalized ion channels and a method making the same

InactiveUS8119273B1Decrease in ion conductivityIon-conductivity can be maximizedCell seperators/membranes/diaphragms/spacersElectrode carriers/collectorsCation PumpIon transporter
The invention relates to a unique battery having an active, porous membrane and method of making the same. More specifically the invention relates to a sealed battery system having a porous, metal oxide membrane with uniform, physicochemically functionalized ion channels capable of adjustable ionic interaction. The physicochemically-active porous membrane purports dual functions: an electronic insulator (separator) and a unidirectional ion-transporter (electrolyte). The electrochemical cell membrane is activated for the transport of ions by contiguous ion coordination sites on the interior two-dimensional surfaces of the trans-membrane unidirectional pores. The membrane material is designed to have physicochemical interaction with ions. Control of the extent of the interactions between the ions and the interior pore walls of the membrane and other materials, chemicals, or structures contained within the pores provides adjustability of the ionic conductivity of the membrane.

High throughput screening of ion channels

Multi-well plates having contoured well designs allow multi-stage high throughput parallel assaying of ion channels or ion transporters. A well of a multi- well plate has a bottom region that is sized and shaped to simultaneous accommodate a sensing electrode and a pipette for delivering, e.g., test compounds, wash fluid, and optionally ligands. Such multi-well plates may be coupled with an instrument having a pipette head and an electrode plate. Such arrangement facilitates fluidic contact between cells and fluids provided via a pipette. It also facilitates washing of wells with buffers or other wash solutions to allow serial exposure of test cells to various reagents or other stimuli. Generally, the design allows control and test experiments to be performed on the same cell (or cells) in a single well.
