Nunc™ Lab-Tek™ Chamber Slide System

Unfortunately, we do not have a recommended cell density for our LabTek Chamber Slides. However, you can refer to the following link, which provides recommended cell densities for our other cell culture products:

The following are possible causes and solutions:
- The cells could be stressed due to media substitution, especially from serum-free formulations, or other changes to the culture environment such as in temperature, humidity, and CO2 percentage. If possible, always plate cells in serum-containing medium. Switching cells to a serum-free media should be done gradually.
- The cells could be plated at very low densities. Most cell lines have a minimal platting density below which normal cell proliferation cannot occur, and therefore should be avoided.
- The cells could be poorly adherent. Treatment of cells that may reduce adhesion and therefore, should not be done immediately after plating, but after the cells have resumed exponential growth.

The upper structure of our Nunc Lab-Tek Chamber Slide products are made of polystyrene so it is not compatible with many fixation reagents. These chamber slide products are designed for upper structure and gasket removal before fixing, staining, and coverslipping.

Our Nunc Lab-Tek Chamber Slide products are used for fluorescence analyses at the microscopic level.
The following are commonly used excitation and emittance wavelengths:
FITC
- Excitation: 420-490 nm
- Emittance: 520-550 nm
Rhodamine
- Excitation: 510-560 nm
- Emittance: 570-610 nm
Hoechst
- Excitation: 330-380 nm
- Emittance: 480-510 nm

We have a Technical Bulletin (link below) describing fixation reagents that are compatible with Permanox plastic: https://assets.thermofisher.com/TFS-Assets/LSG/Application-Notes/D19581.pdf
