Hamamatsu Photonics K.K. Has Developed a Novel 3D Fluorescence Scanning Method Called “Zyncscan™“ That Performs an X-Z Plane Scan With a Light-Sheet for Cell-Based Fluorescence Assays in Microplates

Share

Hamamatsu Photonics K.K. (TOKYO:6965) has developed a novel 3D fluorescence scanning method called “Zyncscan™” that performs x-z plane scans using a light-sheet for cell-based fluorescence assays in microplates. This technology provides an x-z plane scan using a light-sheet for a whole 96/384/1536-well microplate, allowing users to obtain 3D fluorescence images of whole wells in xy: 2-3 μm and z: 6-7 μm voxel resolution for ≤ 300 μm thickness from the well bottom within a few minutes per color. This technology also allows for ultra-high level separation of cell fluorescence signals from the background, which makes it possible to obtain fluorescence cell images in the cell culture mediums containing serum and with fluorescent dyes (i.e., no need to wash out fluorescent dyes).

Background of development

In drug discovery and development, there is a rapidly growing need to use more physiologically-relevant in vitro cell culture models. These include primary cells, patient-derived cells, human iPSC-derived disease-modeling cells, co-cultures of different types of cells, and 3D cultures such as spheroids and organoids. To develop and advance phenotypic assays and screenings using these physiologically-relevant cellular models, new types of instruments needed to be developed to facilitate high-throughput fluorescence imaging and measurement of heterogeneous 2D and 3D cell cultures. To meet this need, we have developed ZyncscanTM technology that performs an x-z plane scan utilizing a light-sheet for a microplate.

Features of the cell-based fluorescence assays in microplate using Zyncscan™ technology

1)   High-speed fluorescence cytometry for 2D monolayer heterogeneous cell culture
A single 120-second scan (one color) for a whole 96/384/1536-well microplate enables fluorescence cytometry of all individual cells in all wells.
2) Single spheroid analyses using depth information (diameter of spheroid; ≤ 200 μm)
A single scan (in just a few minutes) for a microplate enables fluorescence images of spheroids (single or multiple spheroids in a well) in all wells in a 96/384/1536-well microplate. From the images, the entire fluorescence intensity, thickness and volume of each individual spheroid are estimated.
3) Fluorescence images in 3D view (≤ 300 μm)
With a single scan (a few minutes) obtain 3D fluorescence images (300 μm from the bottom of a well) of all wells in a plate. The optical resolution of the image is comparable with the 2x objective of a conventional fluorescence microscope in the x- and y-axes and a 10x objective of confocal fluorescence microscope in the z-axis.
4) In-medium / No dye washout measurement
Measure cellular fluorescence in the medium containing serum and with fluorescent dyes (no need to wash out fluorescent dyes), allowing cells to remain healthy throughout the experiment.
 

Future outlook

Hamamatsu Photonics K.K. has been developing a fluorescence instrument for cell-based assays equipped with Zyncscan™ technology, CYTOQUBE™, a Light-Sheet Microplate Cytometer. We plan to initiate validation and application experiments in several research sites in drug discovery and development by early 2020. CYTOQUBE™ is planned to be released by the end of the next fiscal year (September 2020).

We will showcase a prototype of the CYTOQUBE™ (Light-Sheet Microplate Cytometer) at the following conferences.

Takeda Announces Compelling Data from the Phase 2 Trial of Pevonedistat Plus Azacitidine in Patients with Higher-Risk MDS29.5.2020 14:00:00 CESTPress release

Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) today announced the results of the Phase 2 Pevonedistat-2001 trial will be presented during oral sessions at the virtual 56thAmerican Society of Clinical Oncology (ASCO) Annual Meeting and the virtual 25thEuropean Hematology Association (EHA) Annual Meeting. The study evaluated pevonedistat plus azacitidine versus azacitidine alone in patients with rare leukemias, including higher-risk myelodysplastic syndromes (HR-MDS). These results show that the combination of pevonedistat and azacitidine is a highly active, promising therapeutic approach and suggest benefit in the HR-MDS subgroup across multiple clinically meaningful endpoints, including overall survival (OS), event-free survival (EFS), complete remission (CR) and transfusion independence, with a safety profile similar to azacitidine alone. The Pevonedistat-2001 trial was designed as a proof-of-concept study in patients with HR-MDS, higher-risk chronic myelomonocytic leukemi

Takeda Receives Positive CHMP Opinion for Pre-Filled Syringe Presentation of TAKHZYRO ® (lanadelumab) for Use as a Preventive Treatment for Hereditary Angioedema Attacks29.5.2020 14:00:00 CESTPress release

Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) (“Takeda”) today announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion on a Type II Variation regulatory application and recommended the approval of a pre-filled syringe presentation of TAKHZYRO® (lanadelumab). TAKHZYRO is a subcutaneous injectable prescription medication approved in Europe for routine prevention of recurrent attacks of hereditary angioedema (HAE) in patients aged 12 years and older. HAE is a rare genetic disorder that results in recurrent attacks of oedema – swelling – in various parts of the body, including the abdomen, face, feet, genitals, hands and throat.1,2,3 “Our goal is to continuously innovate in all areas of HAE management,” said Isabel Kalofonos, Global Product Strategy Lead, HAE, Takeda. “This positive opinion marks another important step forward as we aim to enhance the experience of treatment administration for peo
