BlueWasher dramatically shortens wash time for intracellular drug distribution study at AZ

Bomi Jung et. al. at AZ, Gothenburg SWE, in their ELRIG poster "High density assessment of drug distribution profiles in cultured cells" reduced wash time from 20-30 minutes to <1min using the BlueWasher.

BlueWasher enabling 1536w High Throughput (HT) cell based screening

Major hurdles to adopting cell based assays for HT screening are the cost, availability of cells, and complex protocols. Miniaturization to 1536w format  can reduce costs and increase throughput but brings major challenges in liquid handling for high-content assays requiring washing steps and coating of plates. Paper describes the novel application of the BlueWasher to facilitate the miniaturization of a range of 1536w cell assays and techniques to reduce edge effects, improving 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.

Cover Story pharma Tech Outlook:

The BlueWasher, one of pharma Tech Outlook's top 10 Drug Discovery innovations in 2017, is featuring in this cover story. Based on interviews and literature review, it explains why BlueWasher has quickly become the new standard for media change in cellular assays.

BlueWasher and n3D enabling automation-friendly 3D cell screen

Shurong Hou (SCRIPPS, Jupiter, FL), in this SLAS2018 poster, shows how the n3D cell magnetization technology using the BlueWasher for media change and wash retains magnetized cells, allows for effective media evacuation and produces high quality results.

BlueWasher flyer

Using centrifugation instead of aspiration to remove liquids from microplates, BlueWasher reduces residual volumes 10x vs conventional plate washers, reducing background and variability, improving z' for typical adherent cell-based assays by 0.1 to 0.3.

BlueWasher delivering high z' for 1536w drug library screen at SCRIPPS Florida

Shurong Hou et. al. at the Department of Molecular Therapeutics, Scripps Research Institute, Juniper, FL, in their paper "Drug Library Screening for the Identification of Ionophores That Correct the Mistrafficking Disorder Associated with Oxalosis Kidney Disease" describe using BlueWasher for 4 cell wash steps in a miniaturized 1536w high-content assay, reporting a Z′ averaging 0.70 ± 0.07.

Cell-Based In Vitro Assay Automation:  Fewer false negatives with BlueWasher

Adam Weinglass and Mary Jo Wildey (Merck & Co, Kenilworth, NJ) present different ‘technology’ options (Dump/Pat; 384W Plate Washers; Non-contact Centrifugation BlueWasher) for removing assay media prior to compound addition & determination of IP1 accumulation. BlueWasher results showed to be closer to "intrinsic, serum-free compound potency, improve data consistency and decrease the rate of false negatives."  Show example of historically relatively inactive compounds that  aligned when BlueWasher was used for media removal.

Contamination-free plate evacuation wtih BlueWasher

This Technical Note presents data in support of the absence of cross-contamination when evacuating a mircoplate with the BlueWasher.

BlueWasher enabling 1536w HTS, improving z'

Helen Plant (AstraZeneca, Alderley Park, UK) in this SLAS2016 presentation, shows how the BlueWasher enabled conversion of complex, high-content phenotypic high-throughput screens from 384w to 1536w plates, as well as in-house coating of 1536w plates with fibronectin. Near zero residual volume by using centrifugation rather than aspiration is enabling for 1536w formats. Successful conversion to 1536w format resulted in up to a 25% reduction in cells needed and ~4x time reduction to perform a full HTS screening campaign. It has also allowed economical screening of expensive assay formats and cell types in high-content phenotypic HTS screens.
