cellomics automation banner

Cellomics is coined to mean the study of cells and their function. With the further use of live cells, a wide variety of assays can be automated in the cellular environment. Cell-based target validation, secondary screening, lead optimization, and structure-activity relationships are now being replaced with the advent of High Content Screening (HCS). Automated HCS platforms interface fully automated fluorescence microscopy, plate-handling automation, and seamless image analysis.

HCS is a drug discovery method that uses images of living cells as the basic unit for molecule discovery thus increasing the need to grow, maintain and harvest mammalian cells cultures.

High Throughput Cell Plating System
The purpose of the High Throughput Cell Plating System is for the exceptionally reliable, fast, flexible, and efficient automation of plating out multiple cell lines cell. The system can accommodate for deepwell cell line reservoirs and transfer each cell line into multiple 96 or 384 well covered plates. The liquid handling robot system is equipped with dual incubators so both cell line reservoir and destination plates are continually kept in a CO2 incubated environment. The system is set up for extremely high throughput and process 250 destination plates from 50 cell line reservoirs in less than two hours. The liquid handling robot system can be configured to have as any number of destination plates, from single cell lines to single destination plates to all 250 plates containing the same cell line.

Automated Cell Maintenance

Dynamic Devices automated cell maintenance systems solve the daily issues of growing enough cells needed for automate cell based assays. Since the amount of cells is ever increasing, such daily tasks as exchanging spent media for new, splitting cells at certain concentrations to promote further growth and plating cells for assay preparation can be fully automated. By either using a stand alone workstation like the DDi Oasis platform, or a fully integrated DDi liquid handling robot system containing a liquid transfer device, incubators, gripper tools and readers, we can perform some or all of the daily maintenance required for cellular growth to increase a output functions of the lab.

Automation platforms can be configured to reduce manual intervention of the processes such as:

  • Cell harvesting, dilution and splitting
  • Cell counting and media exchange
  • Incubation with monitored and recorded conditions
  • Consistent sample preparation
  • Cell-based assay with internal process control technologies

An example of a cell-based assay workstations based on the DDi Oasis Liquid Handling Robot Platform can be configured with the following:

  1. Oasis Pipetting Platform with disposable tip head, integrated gripper tool, incubation positions and integrated HEPA filter hood.
  2. Integrated CO2 incubator with different storage capacity units ranging from 6 to 500 plates to maintain a stable temperature and CO2 level environment.
  3. Integrated plate reader, various detectors and imagers can be integrated based on the type of reading required for the assay.
  4. Graphical user interface software based on easy to enter variables for each cell type or line.

An example of a cell maintenance system based on an integrated DDi System can be configured with the following:

  1. Oasis Custom Pipetting Platform with disposable tip head, integrated gripper tool, incubation positions and integrated media extraction/fill arm.
  2. Media refrigeration and heating unit to ensure proper storage of the media and heating station to properly deliver the media at a temperature suitable for the cells.
  3. Integrated CO2 incubator with either microplate format or roller bottle type containers to maintain a stable temperature and CO2 level environment.
  4. Optional print and apply barcode printer for customized bar codes containing specific information for each microplate or tube processed.
  5. Bio-contaminate HEPA hood encompassing entire system with interface to large external incubator.

Automated High Throughput Cell Harvesting System Components
Custom OASIS Model LM 1201Base Unit (Cell Harvesting Station): The standard LM 1201 liquid handling robot base unit is a powerful & flexible pipetting workstation for the automation of liquid handling operations. The LM 1201 model is a single arm unit with typically either a 96 or 384-Tip pipette head on the gantry style robotic platform. However, the use of custom tools or end effectors is also quite common. The gantry robot offers a sophisticated linear motor motion control technology for the high-speed & precise movement in the X & Y axis of the robotic end effector(s). For this application the standard liquid handling pipette head has been replaced by a customized two function tool. The two function tool offers rapid capping/de-capping of bottles, as well as the aspiration & transfer of cell harvest. The aspiration tool utilizes an exchangeable disposable tip for either transferring from or to the media bottle. The Capping / De-Capping operation is capable of capping or de-capping a single bottle at one time and maintains the cap within the tool during subsequent aspiration/transferring operations before replacing the cap and moving onto to the next media bottle. This customized two function tool is specially designed for use with the Integra Bioscience Media bottle. The system can accommodate up to 20 media bottles within a single operation.

Biological HEPA Instrument Hood: Biological instrument hood that provides class 100 HEPA filtered air down across workstation within a plexi glass enclosure. The plexi glass enclosure includes doors that can be opened for convenient user access to workstation. The biological hood sits on the table top of the robotic table and encloses the entire workstation. Non-critical items such as the peristaltic pump and media bags can remain outside hood area with only sterile tubing running inside the biological chamber.
