Image-based, automated analysis of 3-D tumor spheroids in microwell plates is becoming standard practice for the evaluation of anticancer drug compounds.
Nexcelom Automated Cell Counters: Accurate, Reproducible Cell Counts for the Entire Cell Therapy Workflow
Cellometer automated cell counters have been facilitating CAR T manufacturing with accurate cell counting and analysis since 2010.
The FDA identifies clonality as one of the most crucial steps in guaranteeing cell line quality and safety. The Celigo Image Cytometer makes single cell sorting easy.
Poster: High-throughput immune complex analysis method for CAR T cell-mediated cytotoxicity using the Celigo Image Cytometer
Download our Poster Abstract: Cancer immunotherapy has been gaining momentum in the field of cancer research. Specifically, Chimeric Antigen Receptor (CAR) T cell technology have introduced new methods to combat cancer. Direct cell-mediated cytotoxicity assays are required to assess the killing capability of the engineered CAR T cells. Traditionally, these assays are conducted by measuring the amount of released Chromium, calcein AM, or LDH molecules after the target cancer cells are killed with CAR T cells. These methods require a large amount of target cells which may not be ideal when working with donor primary samples. Additionally, they cannot [...]
Celigo playing an important role in high throughput, high-resolution image acquisition for DNA damage detection. The Celigo S captures 16 images of each well that are then stitched into a single representation Open access article: Next generation high throughput DNA damage detection platform for genotoxic compound screening
Antibody-directed and drug therapies have been on the forefront of immuno-oncology research in the past 15 years. Since the FDA introduced the Breakthrough Therapy Designation in 2016 for novel promising drug therapies, the number of applicants and approved candidates has increased dramatically. As more and more researchers are looking at drug effects in cancer cells and moving forward in drug discovery, they face many challenges in their day to do work. Performing cell cytotoxicity assays for multiple cell lines with single and combination drug therapies is standard practice in immuno-oncology. While many researches use end-point assays such as MTT, XTT, WST, or CellTiter-Glo, others prefer the manual [...]
Lawrence, Massachusetts – September, 2016 - Nexcelom Bioscience, a leading provider of cell counting and analysis products for biomedical research and the biopharma industry, announced it has released the addition of a 5th channel available as an option on the Celigo image cytometer. The Celigo is a bench-top image cytometry system providing whole-well imaging and quantitative data, through image analysis for demanding cell-based analytical applications. Previous configurations allowed bright field only imaging, or bright field imaging plus 3 fluorescent channels. This new option of bright field plus 4 fluorescent (red, green, blue and far-red) channels will allow researchers more capabilities [...]
Celigo Advances studies in T Cell Therapy as a pediatric CHOP patient defeats her recurrent leukemia with immunotherapy
Emily Whitehead, cancer survivor, holding Nexcelom cell counting sheep. Thanks to the lifesaving T cell therapy clinical trial at Children’s Hospital of Philadelphia, Emily Whitehead is now two years cancer free. Diagnosed with acute lymphoblastic leukemia (ALL) right after her 5th birthday, doctors discovered that Emily’s leukemia was particularly resistant to chemotherapy, as are roughly 15% of the total number of ALL cases. After two recurrences of the disease, Emily’s parents enrolled her in a clinical trial for CTL019, an experimental therapeutic using a patient’s own reprogrammed T cells to eliminate the cancer cells. Now 9 years old, [...]
Recent publications have suggested that using 3D tumor spheroids is a more predictive model for preclinical research. Nexcelom Bioscience has developed a standardized microplate method for rapid generation, imaging and analysis of 3D tumor spheroids using the Celigo image cytometer. 40 cancer cell lines' ability to form spheroids, optimal seeding densities and culture conditions have been established. Protocols measuring tumor growth, viability, migration and invasion have been utilized by many researchers for routine preclinical drug studies. If you are interested to learn more about how your research might benefit from working with 3D tumor spheroids, this is a great place to start! [...]
It's White Paper Wednesday! Read our featured white paper: Increasing Efficiency in Cell Line Development using the Celigo Imaging Cytometer In this study, using the CHO cell line, the Celígo Imaging Cytometer was used to monitor transfection efficiency, identify passaging times, optimize media, identify single cells and track clone outgrowth, following previous studies detailing Celígo's performance in tracking cell lineage and confluence [3, 4]. After transfection, cells were allowed to stabilize, then imaged in bright field and fluorescence to monitor and evaluate transfection efficiencies. As wells grew asynchronously, bright field imaging was used to track which wells needed passaging. As [...]
