Simple, biomimetic tissue culture devices.

Think soft!
The physical properties of the substrate on which cells are grown profoundly influences the culture, as recent scientific data demonstrates. Substrate elasticity is as powerful to determine cell behavior and identity as is their chemical milieu.

Grow soft!
ExCellness provides non-degradable tissue culture surfaces with the elasticity of human tissue, ranging from the stiffness of bone to the softness of brain. Culturing your cells on our adapted culture substrates makes them "FEELING AT HOME"!

Enjoy soft!
Culturing your cells on ExCellness tailored culture substrates allows to:

• determine the optimal mechanical conditions for cells to express proteins of interest appropriay
• model healthy and diseased tissues in vitro
• determine the effect of substrate elasticity on cell proliferation rates, apoptosis, cytokine production, metabolism...

Our solution : biomimetic, elastic cell culture substrates
Our technology is based on the fact that the softness of the culture surface influences cell performance. We offer culture dishes with elastic surfaces that imitate the physical properties of tissues in the human body, ranging from the stiffness of bone to the softness of brain tissues.

PrimeCoat series
 

The ExCellness PrimeCoat series is designed specifically to provide a biomimetic cell culture environment that improves cell characteristics and phenotype in laboratory applications.

Key features

• PrimeCoat elastic substrates are easy to use for cell culture and subsequent analysis.
• PrimeCoat elastic substrates are available with 6 degrees of softness within the elasticity range of body tissues: 2, 5, 10, 15, 30 and 100 kPa.
• PrimeCoat elastic substrates are available in 4 standard formats: 100 mm diameter dishes, 40 mm diameter dishes, 24-well plates and 20x20 mm cover slips.
• PrimeCoat elastic substrates require to be coated by the end user to promote cell adhesion.
• PrimeCoat elastic substrates are transparent. Cells can be visualized with standard transmission light microscopes (e.g., Phase contrast, DIC).
• PrimeCoat elastic substrates are compatible with most standard molecular or cellular techniques: immunofluorescence, immunohistochemistry, protein analysis (e.g., Western blotting, and RNA/DNA extraction).

Biomimetic cell culture substrates at reach

PrimeCoat series combines simplicity and accessibility:

• simplicity of cell handling
• straightforward compatibility with cell analysis tools
• accessible prices
