Multiplexed cell-based assays
Relieve the pressure from microscope-based technologies. Confirm screening hits using a complementary approach.
Raise the productivity of in-house high content imaging
Whether confirming hits derived from HTS screens or establishing early indications of off-target effects, you can instantly improve workflow efficiency by eliminating resource and throughput bottlenecks. Simply transfer routine cell-based assays from microscope-based devices to acumen® Cellista. This alternative solution effortlessly provides decision making data from whole well multiplexed assays in as little as two and a half minutes per microplate (96, 384 and 1,536-well microplates). Read about featured applications below.
A versatile approach for cell health determination and compound profiling
Whether screening for cytotoxic or cytoprotective agents, or to identify potential off-target drug effects early, multiplexed cell health assays play a key role within drug discovery. The extent of cell death can be determined in simple live/dead screens using standard dyes (such as calcein-AM and propidium iodide).
Deeper profiling to distinguish between the various pathways may be achieved through further multiplexing (caspase, annexin V, nuclear condensation, mitochondrial health) or multiparametric readouts (cell proliferation and cell cycle) to provide valuable insights into mechanism of action.
Rapid multiplexed cell cycle analysis
The effect of compounds on the cell cycle is a widely studied application. Traditionally, flow cytometry is used to characterise DNA content, however, plate-based imaging using acumen Cellista® is more amenable to automation.
DNA binding dyes used to quantify cell cycle phases may be re-analysed over time to monitor kinetics, or multiplexed to identify the expression of disease relevant proteins or cell cycle markers. Adherent cells are analysed in-situ to preserve their morphology and results normalised to total cell number highlight cytotoxicity or cytostasis.
Robust determination of protein kinase activation
Protein kinases play an important role in regulating many of the building blocks of living systems. Their abnormal activity commonly results in diseased states. Signalling cascades have traditionally been monitored by biochemical and lysate-based assays, however these approaches offer low content data reporting.
Through an image-based approach, you can determine compound effects on the activation of multiple kinases within the context of a whole cell and derive detailed pathway analysis.
Speeding up angiogenesis detection assays
Angiogenesis is a fundamental multistep process by which new capillary blood vessels grow from pre-existing vasculature and is critical in the progression of tumours moving from dormancy to malignancy.
Using a microscope-based approach, angiogenic tube formation assays require entire well areas to be analysed in order to gain robust, statistically significant data, however, this can result in lengthy microplate read times. We have developed a simple application for analysing tube formation from the entire well area of microplates in just five minutes. Open source TIFF images from wells of interest may be exported for in depth analysis using third party image analysis packages.
