High-Throughput / High-Content Screening Applications

3D CoSeedis™ is an ideally suited production tool to grow spheroidal 3D cell constructs in large scale, particularly for the use in HTS/HCS applications. With the various formats (2x2, 1x1, 0.5x0.5), it is possible to grow up to 1’200, 5’280, and 16’320 spheroids per plate, respectively.

The major advantages for subsequent HTS/HCS are:

• 3D CoSeedis™ matrix consists of agarose => biologically inert carrier matrix
• Substantial reduction of cell culture work (50’000 3D constructs/day ® 3 – 10  3D CoSeedis™ plates).
  > 5’000 3D constructs per 6-well plate; >16’000 per 24-well plate.
• Highly reproducible and homogeneous 3D cell aggregates across matrix and plates.
• Increased screening efficiency through highly homogenous 384-well plates seeded with 1 to several 3D constructs / well.
• Long-term studies possible: up to 70 days in culture.
• Dual and sequential treatments possible over extended
  period of time with lots of up to 900 cell aggregates.
• Fully validated for a wide range of tumour 3D aggregates.
• Modular set-up (e.g. distance co-cultures) significantly extends
  the range of testable cells in 3D including primary cells and iPS.
• Fully validated read-outs:
  • Growth monitoring
  • Viability
  • Cytotoxicity
  • Histology: paraffin and frozen
  • Colony forming assay

For further details you may also refer to the following Whitepaper.

Viability / Cytotoxicity

The application note addresses viability and/or cytotoxicity of 3D cell constructs grown in 3D CoSeedis™. The protocol describes an extension to all existing 3D CoSeedis™ systems and can be implemented easily without further requirements in equipment or appliances.

 

Cryo-embedding

3D CoSeedis™ offers an easy and elegant way to embed 3D constructs for cryo-sectioning without the need to manipulate individual spheroids. It reduces tricky and cumbersome manipulations and prevents damage or loss of 3D constructs.
