Applications of Countstarin cancer cell research The Countstar system combines the image cytometer and cell counter into a single bench-top instrument. This application-driven, compact, and automated cell imaging system provides an all-in-one solution for cancer cell research, including cell counting, viability (AO/PI, trypan blue), apoptosis (Annexin V-FITC/PI), cell cycle (PI), and GFP/RFP transfection. Abstract Cancer is one of the main causes of death worldwide, and the development of new cancer treatment methods is of great significance. Cancer cell is the basic research object of cancer, various information needs to be evaluated from the cancer cell. This research area needs rapid, reliable, simple and detailed cell analysis. Countstar system provides a simple solution platform for cancer cell analysis.

Dual Fluorescence Method Analyzing Blood and Primary Cells Blood and freshly isolated primary cells or cultured cells may contain impurities, several cell types or interfering particles such as cell debris which will make it impossible to analyze the cells of interest. Countstar FL with dual fluorescence method analysis can exclude cell fragments, debris and artifacts particles as well as undersized events such as platelets, giving a highly accurate result. Table of Content AO/PI Dual Fluorescence Viability Counting WBCs in Whole Blood Counting and Viability of PBMC AO/PI Dual Fluorescence Viability Counting Figure 1 Procedure AO/PI Dual Fluorescence Viability Counting in Countstar FL Acridine orange (AO) and Propidium iodide (PI) are nuclear nucleic acid binding dyes. The analysis excludes cell fragments, debris and artifacts particles as well as undersized events such as red blood cell, giving a highly accurate result. In conclusion, the Countstar sy...

Mammalian cells are widely used in Biopharmaceuticals, such as antibodies, vaccine, peptides and secondary metabolites are produced by bioprocessing with mammalian cells. During the whole process from antibody R&D to production, there are many steps need to carry out cell based assay to evaluate the process or quality control. Such as the total cell concentration and viability will define the status of the cell culture. As well as the cell transfection, antibody affinity determine at cell level. Countstar instruments are the image based cytometry, can help monitor from R&D to production processes and ensure reproducibility and consistency. Table of Content Cell Count and Viability by Trypan Blue Viability and GFP Transfection Determination in Cells Affinity of antibody detection on Countstar Rigel Countstar is GMP-ready for 21 CFR Part 11 Cell Count and Viability by Trypan Blue Monitoring and analyzing cell culture with state-of-the-art solutions.

Determination of viability, morphology and phenotype for stem cell therapy Mesenchymal stem cells are a subset of pluripotent stem cells which can be isolated from the mesoderm. With their self-replication renewal and multi-direction differentiation characteristics, they possess a high potential for various therapies in medicine. Mesenchymal stem cells have a unique immune phenotype and immune regulation ability. Therefore, mesenchymal stem cells are already widely used in stem cell transplantations, tissue engineering and organ transplantation. And Beyond these applications, they are used as an ideal tool in tissue engineering as seeder cells in a series of basic and clinical research experiments. stem cell analysis The Countstar FL can monitor the concentration, viability, apoptosis analysis and phenotype characteristics (and their changes) during the production and differentiation of these stem cells. The Countstar FL has also the advantage in obtaining additional morphologic...

Cell therapy is undoubtedly a new hope to lead the future of biomedicine, but the application of human cells in medicine is not a new concept. In the past few decades, cell therapy has made great progress, and cell therapy itself is no longer a simple collection of cells and infused back. Cells are now often required to be bioengineered, such as CAR-T cell therapy. We aim to provide you with standardized, GMP level equipment for cell quality control. The Countstar product has been accepted by many companies leading the cell therapy, we can help our customer to build a stable, reliable cell concentration, viability monitor system.
