BlueWasher enables automation-friendly workflow for 3D cellular screening with n3D cell magnetization technology
More Productive Discovery
Our BlueWasher's award-winning ability to improve z' for adherent cellular assays makes it the most cost-effective tool to boost drug discovery productivity. Residual volumes 10x lower than conventional, tip-based plate washers reduce assay background and variability, allowing imagers to produce even better data. Ideal for assay development, high-throughput screening (HTS), high-content screening (HCS), 3 dimensional cell screens with n3D, FLIPR®, or expression assays, including 1536w, as part of a fully automated system, or a stand-alone workstation.

Cell-based assays have long been important within hit discovery paradigms; however, improving the disease relevance of the assay system can positively affect the translation of small-molecule drug discovery, especially if adopted in the initial hit identification assay. Consequently, there is an increasing need for disease-relevant assay systems capable of running at large scale, including the use of induced pluripotent stem cells and donor-derived primary cells. Major hurdles to adopting these assays for high-throughput screening are the cost, availability of cells, and complex protocols. Miniaturization of such assays to 1536-well format is an approach that can reduce costs and increase throughput. Adaptation of these complex cell assays to 1536-well format brings major challenges in liquid handling for high-content assays requiring washing steps and coating of plates. In addition, problematic edge effects and reduced assay quality are frequently encountered. In this study, we describe the novel application of a centrifugal plate washer to facilitate miniaturization of a range of 1536-well cell assays and techniques to reduce edge effects, all of which improved throughput and data quality. Cell assays currently limited in throughput because of cost and complex protocols may be enabled by the techniques presented in this study.

Three-dimensional (3D) cell models are thought to better mimic the complexity of in vivo tumors. We have previously enabled an HTS-compatible method using cell-repellent plates combined with a magnetic force bioprinting technology that affords large scale testing of spheroids and organoids in flat-bottom 384 and 1536 well plates. This type of 3D biology requires tissue culture in suspension which makes feeding, media transfers, washing, etc., problematic. To address this we combined the 384 well formatted magnetic 3D (m3D) Bioprinting technology with the utility of the BlueWasher equipped with magnetic spin features. We validated this system for rapid removal and replacement of media to facilitate adaptation of a non-homogeneous format within 3D HTS. Our work demonstrates the effectiveness of both the m3D bioprinting system and the BlueWasher in the following aspects in 384 well plates: 1) Retention of 3D spheroids and their integrity 2) Precision and accuracy of liquid manipulation 3) Qualification in terms of compound controls, Z’ and S:B when using phenotypic 3D primary pancreatic tumor cell based assays.
