GastroSense 750 is a near-infrared, fluorescently-labeled macromolecule that may be used to monitor the effects of disease or drugs on gastric motility and or gastric emptying. It may also be used as an anatomical marker for the gastrointestinal tract.
GastroSense 750 may also be administered as part of a solid diet by applying the reconstituted solution to egg yolk. When added to a solid diet it may be easier to reconstitute the vial of GastroSense 750 with 300 µL of 1x PBS and use 25 µL per mouse. GastroSense remains localized in the GI tract. It does not appear to be absorbed into the bloodstream.

The accurate quantitation of gastric emptying is crucial,for understanding the physiological, pathological and,pharmacological mechanisms underlying gastric motility,both clinically and in animal studies. Current methods,used for determining gastric emptying rates in small animals,are either terminal or involve radioactive tracers, incurring,high financial and time cost. We have developed a novel,near-infrared (NIR) fluorescent imaging agent, GastroSense™ 750, to monitor and quantitate gastric,emptying rates in murine models in vivo, non-invasively, and in real time. The imaging agent is,comprised of an acid-stable NIR fluorophore conjugated to a non-absorbable pharmacokinetic,modifier designed to be formulated in liquid or incorporated into a solid meal. Using female,8 week old BALB/c mice recipients, 0.25 nmol GastroSense 750 was orally gavaged in liquid,formulation (PBS) or fed in egg yolk, an experimental approach designed to detect changes in,gastric emptying.

The primary goal of preclinical imaging is to improve the odds of clinical success and reduce drug discovery and development time and costs. Advances in non-invasive in vivo imaging techniques have raised the use of animal models in drug discovery and development to a new level by enabling quick and efficient drug screening and evaluation. Read this White Paper to learn how preclinical in vivo imaging helps to ensure that smart choices are made by providing Go/No-Go decisions and de-risking drug candidates early on, significantly reducing time to the clinic and lowering costs all while maximizing biological understanding.
