CnT-Prime Airway is a fully defined, animal-component-free medium for the isolation and expansion of large airway epithelial cells. It was developed using human tissue, but may also be used with other species (e.g. mouse).

It can easily be upgraded for clinical applications. Contact us at scientist@cellntec.com for further details and pricing.

It is an evolution and refinement of our previous airway medium CnT-17.

It uses an optimsed 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 to efficient isolation and extended longevity, and co-factors to improve growth factor binding to membrane-bound receptors.

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 undergo a range of QC tests in our lab before being released for sale. Please see the datasheet for details.

CnT-Prime Airway, Epithelial Culture Medium

CnT-Prime Airway is a fully defined, low calcium (0.07 mM) medium formulation designed for optimal isolation, growth and longevity of primary epithelial cells. It is completely free of animal or human-derived components. CnT-Prime Airway contains a full range of amino acids, minerals, vitamins and organic compounds, plus growth factors to deliver strong cell proliferation, and cofactors to improve growth factor binding to cell surface receptors. CnT-Prime Airway also contains PCT factors that maximise retention of proliferative progenitor cells, increase longevity, and minimise loss through differentiation. It does not contain phenol-red, or antibiotics / antimycotics.

Developed for primary human airway epithelial cells. May be used for other species as well, including mouse.
Tissue type
Pack size
500 mL bottle, fully supplemented with growth factors. No further additions required.
Product use
Developed specifically to deliver efficient isolation, strong proliferation and extended longevity of primary airway epithelial cells in a fully defined environment. The inclusion of PCT factors increases retention of proliferative progenitor cells, and minimise loss through differentiation. Not recommended for use when inducing terminal differentiation. For differentiation work, please use CnT-PR-AD medium.
Media Type
Culture condition
This medium is designed for use in a 5% CO2 atmosphere. For suggested isolation, passaging, differentiation and freezing protocols, please visit the resources section of www.cellntec.com
For routine cell cultivation, CELLnTEC does not recommend the use of antibiotics / antimycotics. During isolation, antibiotics / antimycotics are recommended up until the end of P1.
Storage / Shelf life
Store frozen below -15 °C. For best before date, see label. To prepare medium for use, thaw in a water bath set to room temperature. Do not use higher temperatures. Swirl frequently, approximately every 20 min, to ensure good mixing of the ingredients and temperature equilibration. Stop at melting of the last bit of ice to prevent warming at the end of the thawing process. Once thawed, medium has a remaining shelf-life of 6 weeks when stored at 4 °C in the dark. Certain culture media components are very sensitive to light. Minimize light exposure at all times.
Quality control
Media composition is tested via osmolality, pH and the concentration of various ions. Media functionality is tested by evaluating growth and morphology or primary human epithelial cells over at least 2 passages. Free of bacteria, fungi and mycoplasma contamination.
Shipping condition
Medium is shipped frozen.
Intended use
For research use only. Not for use in therapy or diagnostics.
