Automation and flexibility for accelerated assay development
The goal of assay development is to deliver specific procedures to assess or quantify the presence, amount or function of one or multiple target molecules. Immunoassays (e.g., ELISA) and molecular assays (e.g., qPCR) often provide the basis for sensitive diagnostic tests, while biochemical and cell-based assays play a pivotal role in drug development.
Accelerating drug development
In the drug discovery process, assay development aims to deliver specific procedures for assessing a compound or examining a compound’s effects on the identified cellular or biochemical target. Therefore, robust assay development is an integral step when significant effort and costs can be eliminated by screening for nonviable candidates early in the process. Often tens of thousands of compounds need to be screened using uniquely designed biochemical or cell-based assays, so it is important to have a flexible platform for a wide range of assays. CELLINK provides key instrumentation for efficient, high-throughput assay development, including solutions for highly multiplexed low-volume liquid handling, automated live-cell imaging and a variety of bioprinters to create 3D cell cultures, which offer a better representation of activity response than 2D.

Miniaturization and flexibility for assay development
The I.DOT can readily dispense into standard microwell plates (including 384, 1536 and higher density formats), allowing assay miniaturization and high-throughput screening of different drugs and bio-compounds. A single I.DOT source well plate can contain up to 96 different compounds, and multiple permutations of drug concentrations across the well plate with different drug mixtures in each well can be generated. This flexibility enables fast screening of various compounds and reagent compositions.
The I.DOT can dispense volumes as low as 8 nanoliters, allowing for extreme miniaturization of reaction volumes. Even the most complex liquid-handling tasks can be performed within minutes due to the I.DOT´s ability of highly parallel non-contact dispensing. Cost savings are often significant, especially since no pipette tips are required.
The I.DOT is simple to use and requires little maintenance, making it the ideal instrument for laboratories that work on a variety of different molecular assays, including single-cell omics methods, qPCR and NGS library preparation, as well as cell-based assays.
Easy generation of 3D cell culture
Certainly, 3D cell cultures provide several advantages over 2D cell cultures for assay development. The former often better simulate the environment of the tissue of interest, maintain important interactions between cells and are a more realistic representation of how cells and tissues are organized. While the I.DOT is an ideal tool for cell dispensing and for generating organoids, our bioprinters such as the BIO X or BIO X6 allow for rapid generation of complex 3D tissue models. In addition, we offer a variety of ready-to-use bioinks and protocols for different tissue and disease models.
High-throughput imaging for live cell monitoring
The CELLCYTE X offers live cell imaging for online tracking of cell behavior in response to various compounds. The imager features three fluorescent channels, which enable flexibility with common fluorescent-based measurements used in assay development. The device is compact and readily fits in an incubator for time-lapse cell imaging. The system significantly increases walk-away time and helps automate cell-based assays. In addition, it comes with built-in tools for the analysis of cell proliferation, cell viability, cell migration and more.
