3D InSight™ Rat Islet Microtissues (early access)
Production lead time: 4 weeks
Uniform Cellular Composition and Size Distribution
3D InSight™ Rat Islet Microtissues display a cellular architecture with most of the β cells in the core, and the non-β cells in the mantle, similar to the organization observed in native rat pancreatic islets.
Convenient Assay-ready Delivery Format
3D InSight™ Islet Microtissues are delivered in our patented microtissue assay plate. The plate's SureXchange™ ledge enables simple medium exchange for islet maintenance and compound dosing.
- Acute and chronic efficacy/toxicity testing for novel compounds in reference to characterized compounds that influence β-cell viability and/or function
- Histology-based proliferation and apoptosis assays in β-cells
- Testing of human donor-donor differences for functional β-cell responses
- Cross species translatability testing with 3D InSight™ Human and Rat Islet Microtissues
Endpoints for viability and function:
- ATP content
- Insulin content
- Chronic insulin secretion
- Glucose-stimulated insulin secretion (GSIS)
- Caspase assays for apoptosis analysis (In development)
- β-cell proliferation assays (PDX-1/EdU)
