New Bright Field Through Path (Standard)

New mechanism to move the disks out of the light path allows much easier projection of confocal and non-confocal images such as phase contrast.

Simultaneous Dual Color Imaging Mechanisms
(T2 and T3 Models)

CSU-W1 offers single camera split-view model, in addition to the dual camera model which are much improved from those for the CSU-X1. Thanks to the wide FOV, even the split-view offers 2 times wider image area than with older model. By using various dichroic mirrors, it is possible to select various dye-combinations for dual-color imaging*1 with both the two camera model and split-view model.

Details

CSU-W1 offers selection from a total of three basic configurations, two pinhole sizes, options for near infrared observation and an external light path which is useful for versatile applications such as photo bleaching, while bright field light path is now a standard feature. All switching mechanisms in the CSU-W1 are fully motorized and thus ready for automated experiments.

Basic Configurations

CSU-W1 provides a total of three basic configurations for multi- color imaging; 1) Sequential imaging with one camera and a filter wheel, 2) Simultaneous two-color imaging with two cameras, and 3) Split-view two color imaging with one camera shared by 2 optical paths. All features are upgradable after installation.

Option

SoRa disk

Optical resolution has been improved by approximately 1.4x using a super-resolution technique based on spinning-disk confocal technology. Furthermore, a final resolution approximately twice that of the optical limit is realized through deconvolution.

Uniformizer

Most suitable option for CSU-W1 illumination uniformity. Uniform and efficient illumination of the entire wide field of view.
About Uniformizer:More info

Near Infrared (NIR) Port

NIR port provides up to 785nm excitation capability to allow less-invasive deep imaging. The NIR laser is introduced via a dedicated optical fiber in the same way as visible lasers. It is possible to combine NIR and visible lasers within the CSU-W1 unit to allow simultaneous excitation.

External Light Path

External light path provides the direct path bypassing the disk s to microscope. Versatile applications such as photo activation are available by introducing an external light scanner through this port.

Lens Switcher

Newly designed motorized lens switcher between 2 relay lenses i s useful for fitting CSU-W1 image size with various camera types, and also for easy magnification change without exchanging objective lenses.

Variable Aperture

Variable aperture to change laser illumination area, and thus the imaging area by the CSU-W1, is useful to minimize laser damages in the specimen.

Overview:

Over past 20 years, YOKOGAWA proprietary Spinning Disk Confocal technology has been widely used as an indispensable imaging tool among top researchers. The technology enables faster live-cell observation with clearer and less photo-bleaching imaging.

Overview:

In the last few decades, the pharmaceutical industry has transformed people’s lives. However, the development of new drugs is becoming increasingly difficult and a paradigm shift in the drug discovery workflow is required to reduce attrition and transform conventional drug screening assays into translatable analytical techniques for the analysis of drugs in complex environments, both in-vitro and ex-vivo. The ability to visualize unlabelled compounds inside the cell at physiological dosages can offer valuable insight into the compound behavior both on and off-target.

SiLC-MS is a semi-automated methodology that allows the collection of intracellular contents using a modified CQ1 imaging system developed by Yokowaga. The instrument is equipped with a confocal microscope that allows bright field imaging as well as fluorescence imaging with 4 lasers (405, 488, 561, and 640 nm). Sampling is performed using the tips developed by Professor Masujima (1-4).

In this study, we show the applicability of the SiLC-MS technology to drug discovery, as it is crucial to identify compound and its metabolites when incubated in a mammalian cell at a therapeutic dose. We report on the validation studies performed using the SiLC-MS platform, in these validation studies we assess the ability to distinguish different cell types based on their metabolomic fingerprint, furthermore, we have also evaluated if this assay was sensitive enough to detect drugs intracellularly.
