Catalog HPEKas
Content Vial containing 0.5 million viable cells, frozen


  • Extended lifespan of the cells
  • Pre-equilibrated in CELLnTEC base chemistry
  • Retention of proliferative progenitors and reduced differentiation
  • Supplied in fully-defined cryopreservation medium to maximize recovery after thawing


HPEKas primary human epidermal keratinocytes (single adult donor) growing in CnT-PR medium benefit from the presence of PCT factors that aid retention of proliferative progenitors, and reduce differentiation. HANDLING INSTRUCTION: This material is of human origin and should therefore be handled as hazardous. Although it has been tested negative for HIV 1, Hepatitis B, and Hepatitis C, treat this material as potentially infectious and use appropriate biocontainment, protective equipment, and other precautions to prevent accidental exposure.

Scientific resources

The culturing medium CnT-PR consists of PCT factors that aid the retention of proliferative progenitors and reduce differentiation of HPEKas cells. This extends not only the lifespan of the cells but importantly also the period during which the cells retain the ability to complete complex processes such as 3D differentiation.

The HPEK cells are provided cryopreserved in the fully defined CRYO-Defined culture medium to maximize recovery after thawing.

The cultures undergo a range of QC tests in our lab before being released for sale and are also covered by our longevity guarantee. Please see the datasheet for details.

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