Scientific resources

CnT-PR-EF is a low growth factor culture medium that can be used for the differentiation of iPS cells. It does not contain antibiotics / antimycotics, and is free of EGF and FGF.

For detailed instructions of how CnT-PR-EF can be supplemented to induce iPSC to differentiate into corneal epithelium, please see Nature Protocols (Hayashi et al. 2017).

The medium undergoes a range of QC tests in our lab before being released for sale. Please see the datasheet for details. It can easily be upgraded for clinical applications. Contact us at support@cellntec.com for further details and pricing.

Thawing, seeding and passaging protocols are particularly important for optimal cell growth. Please visit our Protocols Page for our recommendations.
