Scientific resources

CnT-PR-A is a chemically defined, low calcium (0.07 mM) medium formulation designed for optimal isolation, expansion, and longevity of primary large airway epithelial cells. It is an evolution and refinement of our previous airway medium CnT-17.

It uses an optimized basal medium with additional trace elements, protective antioxidants, and vitamins. This basal medium is then supplemented with a range of Progenitor Cell Targeted (PCT) growth factors for efficient isolation and extended longevity, and co-factors to improve growth factor binding to membrane-bound receptors.

It is completely free of animal or human-derived components. CnT-PR-A contains purified growth factors, an optimized basal medium to increase cell proliferation, and PCT factors to maximize retention of proliferative progenitor cells, increase longevity, and minimize loss through differentiation. It does not contain phenol-red, or antibiotics / antimycotics.

Large airway cells growing in CnT-PR-A retain deliver extended growth. For differentiation experiments, it is recommended to switch to the CnT-PR-AD differentiation medium.

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.
