the next generation for in vitro testing with faster actionable data.

Supportive, Consultant Approach with Outsourced Services

Passionate Partner

Altis Biosystems is a passionate and motivated partner that works with you throughout the screening or disease modeling process.

Project Ideas

Altis will work with you to design the best project for your needs that will deliver a solid project with scientifically sound results.

Necessary Materials

RepliGut® kits include the necessary materials researchers need to culture cells in their own facility along with consultation throughout the entire cell culture process.

Collaborative Environment

Altis creates an environment of collaboration with you, a key ingredient to driving valuable, actionable insight

Intestinal Barrier Function

Integrity of the intestinal epithelium is crucial for the normal functioning of the lower GI tract. RepliGut® maintains barrier integrity with high TEER values. Compounds can be assessed for the potential to disrupt barrier function.

Inflammatory Response

Inflammation of the GI tract is the main hallmark of Inflammatory Bowel Disease. The RepliGut® system is comprised of polarized intestinal cells grown on transwells. Dosing with compounds can be in the luminal or basolateral compartments and sampling for the release of inflammatory mediators can be quantified in either compartment as well.

GI Toxicity

GI toxicities are among the most common adverse events during Phase 1 clinical trials. RepliGut® recapitulates intestinal epithelium and can be used to screen compounds for drug-induced GI toxicity early in the drug development process.

Intestinal Drug Disposition

RepliGut® can be used to measure the uptake or efflux of compounds in a manner similar to Caco-2 cells. RepliGut® is superior to Caco-2 cells because the cells are not transformed, and studies can be conducted with cells derived from the different regions of the small intestine and colon. More than one donor can be tested.
