Only exchanging to cold medium, collecting adherent cells without any damages

Cepallet® series


Cepallet® is temperature-reacting cultureware whose surface is hydrophobic and adhesive property to cell during cell culturing, while it changes to hydrophilic and un-adhesive property at the lower temperature. Cultured cells can be harvested simply by adding a cold medium with Cepallet®. The damage to cells is suppressed due to not using enzyme or scraper.



  • Simple steps
    ・ Only exchange to cold medium
    ・ No operations such as rinse in PBS or enzyme treatments
    ・ Suitable for automated cell culture system/li>
  • No damage and High recovery rate
    ・ No enzyme and scraping process
    ・ No damage to antigens on the surface of the cell
    ・ Suppress cell re-adhesion


The usage of Cepallet® in culturing and collecting

Cell Culture

    • Your cells can be seeded in the same way as usual.
    • The media is recommended that it is previously warmed at 37 ℃.
    • When the temperature of the medium decreases, the cells will be easy to exfoliate. Therefore, long-term microscopic observation should not be recommended.
    • Coating of extracellular matrices are possibly effective for cells which do not adhere well.
      (Due to the property of the product, we recommend a longer incubation period than the usual coating. And, coating of matrices may not go well at low temperatures.)

Cell Harvesting

      1. Surface of Cepallet® becomes hydrophilic below 32 ℃ and cells are difficult to adhere on the substrate.
      2. After cell culture, the Cepallet® is removed from the incubator.
      3. Remove the medium using an aspirator.
      4. Add 4℃ cooled medium to the Cepallet® and let it stand for 5 minutes at room temperature. (It will return to room temperature in about 1 minute.)
      5. If you are concerned about the addition of the medium at 4 ℃, you can use the medium at 20 ℃ and leave it at room temperature for about 30 minutes.
      6. Pipetting of medium can be good for the detachment of cells in case cells can not be collected completely.
        However, there are sometimes low collecting rate depends on a kind of cells or culture conditions.
