Organoid and Tissue Modeling Shared Resource

Tissue Culture Reagent Services

The OTMSR provides a variety of conditioned medias, matrigel, supplements, and growth factors to enable even the most advanced organoid culture systems.

Conditioned Medias

The OTMSR stocks a variety of cell lines for the production of conditioned medias. Conditioned media is pooled, sterile filtered, and quality tested with luciferase or ELISA assay to determine growth factor activity or concentrations. Additionally, all medias are functionally tested on standardized OTMSR organoid lines to ensure normal morphometry and growth characteristics.

Complete Organoid Medias

The OTMSR provides a range of fully prepared custom medias for most organoid applications. Additionally, the OTMSR can formulate custom medias to meet specific research needs. Custom medias can be designed for tissue-specific mouse or human organoids. All complete medias are made to order using the OTMSR's conditioned media and assorted supplements. To identify the correct media for your organoid application, please schedule an initial consultation on iLabs.
