Valley of death

Within the drug development market, demands on High Content Analysis systems for drug efficacy evaluation are increasing in accordance with the needs for cell-based assay and phenotypic screening. In order to increase screening efficiency, devices with higher speeds (higher throughput) are required.
On the other hand, in order to bridge the “valley of death” of the drug development process, the quality of screening hits must be increased.
This requires the construction of more complex evaluation systems that utilize multifaceted parameters via 3D cultivation systems, live-cell imaging and higher detail image analysis.
In current drug development research, determining how to implement throughput screening and complex evaluation system screening in parallel is an important issue.


The CellVoyager CV8000 is a high-end, High Content Analysis system that solves this contradictory screening challenge. Through the combination of a proprietary Yokogawa High Speed Confocal Scanner, water immersion lens, up to four high field-of-vision cameras, a microscopic stage with cell cultivation environment, and an integrated robotic pipetter, we have realized not only high throughput, high-resolution imaging, but also phenotypic screening via a more complex evaluation system. In addition, our specialized analysis software, CellPathfinder, uses deep leaning and machine learning to recognize target objects with high accuracy, supporting you from image analysis to results display using graphs.

State-of-the-art technology that enables you to do what you want

Observe cells as they are -Dual spinning disk confocal system-

Dual spinning disk confocal system

A Yokogawa proprietary multi-scan method utilizing approximately 1,000 laser beams on the observation region and tandem disks rotating at high speed. The disks comprise a pinhole array disk with approximately 20,000 pinholes arranged in an equal pitch spiral pattern, and a microlens array disk that focuses the excitation light laser into individual pinholes. Not only does this allow high speed imaging, but it also largely prevents phototoxicity and fluorescence photobleaching.

Deeper, clearer observation -Pinhole disk exchanger-

Pinhole disk exchanger
Pinhole disk exchanger

Two different types of pinhole disks (25/50μm) can be used, according to the sample. For thick samples, reducing the pinhole diameter allows for higher confocality, shaper images. For dark samples, increasing the pinhole diameter allows for brighter images.

Organoid imaging example Upper:25μm pinhole Lower:50μm pinhole

Higher throughput screening -Optical configuration-

Optical configuration

The optical system configuration can be selected according to the purpose. A single 96-well plate can be imaged in four colors in one minute by attaching four high- sensitivity wide -field sCMOS cameras. The system is also compatible with FRET and CellPainting assay.

Capturing finer structures -Original water immersion lens-

water immersion lens

Water immersion lenses excel in capturing high-resolution images of cells within a liquid. The CV8000 can be equipped wit h a 40x or 60x water immersion objective lens. Our 40x lens is a particularly unique lens capable of highly advanced spherical aberration correction, allowing for the capture of bright high-resolution images over a full wide -field. The lens water supply is also completely automated. This equipment makes high throughput screening via water submersion lens possible.

Capturing live cell movement -High-precision incubator and robot pipetter-

robot pipetter

The stage incubator features an airtight construction, managing humidity, temperature and CO2 levels. The integrated robotic pipetter conducts the following process fully automatically: tip pickup → reagent collection from the reagent plate → reagent addition to the sample plate → tip disposal. Not only can images be rapidly obtained before and after reagent instillation, but it’s also possible to add reagents to single wells multiple times, and adjust the addition speed etc., broadening the range of dynamics observation via reagent instillation.

A more live cell-friendly total HCA system

Making long-duration live-cell imaging possible -Featuring a s table built -in stage incubator-

HeLa cells were seeded in a 96 well plate at a density of 500 cells per well, and cultured for 24 hours. The well plate was then placed in the internal stage incubator and cell culturing was conducted for 72 hour s, and the total area (hereinafter Total Area) occupied by cells was analyzed. As a result, minimal unevenness in cell multiplication was observed across the 96-wells (excluding the four corner wells) when compared to a regular CO2 incubator.

Cell multiplication comparison with regular CO<sub>2</sub> incubator after 72hr incubation

Cell multiplication comparison with regular CO2 incubator after 72hr incubation(n=3)

  • 96 well average: 90
  • Average of outermost 36 wells: 81
  • Average of 60 wells (excl. outermost): 96

The values represent the following: CV8000 Total Area after 72hrs / Total Area at 0hrs (hereinafter Total Area ratio) / CO2 incubator Total Area ratio x 100.
(Numbers near to 100 me an that cell multiplication was approximately equal for the CV8000 and CO2 incubator.)
Cell multiplication near to that of the CO2 incubator was verified, excluding the four corner wells.

In this webinar, Professor Jonny Sexton discusses a pipeline, developed in the Sexton lab, for the quantitative high-throughput image-based screening of SARS-CoV-2 infection to identify potential antiviral mechanisms and allow selection of appropriate drug combinations to treat COVID-19. This webinar presents evidence that morphological profiling can robustly identify new potential therapeutics against SARS-CoV-2 infection as well as drugs that potentially worsen COVID-19 outcomes.


Human pluripotent stem cells are proven efficient models for drug screening campaigns. They provide access to unlimited starting material amenable to high throughput small molecule compound screening. Due to their capacity to generate mode complex cellular models, they also offer the potential to perform high content screening in tissue-specific organoids for further human target validation.

Dr. Alejandro Hidalgo-Gonzalez at MCRI(Murdoch Children's Research Institute) in Australia is a user of our HCA system CellVoyager CV8000 and he has established a pipeline for assay development and automated unbiased phenotypic drug screening using human pluripotent stem cell-derived cells and organoids. This is a recording of his presentation at an educational webinar organized by A*STAR in Singapore.
