Designed for measuring drug, nutrient, water, and other transport across intact intestine
The base package is comprised of six tubular Ussing chambers, a chamber holder, a water bath, Tygon tubing for the perfusion lines, and an assembly tool. Temperature in the water bath (tray) is maintained by a thermostatically controlled circulator such as our Grant TC-120.
An additional accessory needed to complete the system are peristaltic pumps (up to 12 channels) sufficient to drive solution through both the luminal and extraluminal spaces associated with each of the six intestinal sections.
The Tubular Ussing System is designed to support up to six intestinal sections ranging in length from 2 to 8 cm within small plastic tubes that are then submerged in a thermostatically controlled waterbath. The intestinal sections are cannulated onto movable supports that allow the section to be positioned without stretch within the chamber tube without contacting the tube walls.
Perfusing solutions, usually with dissimilar composition, flow independently through the luminal and extraluminal sides of the intestine. This configuration allows samples to be collected from either side of the intestine over time for longitudinal transport measurements.
