Technology Research & Development Manager | Nexcelom Bioscience
Leo Chan, Ph.D. currently serves as the Technology R&D Manager at Nexcelom Bioscience, Lawrence, MA. For the last 10 years, he was involved in the development of instruments and applications for the Cellometer, Cellaca, and Celigo high-throughput image cytometry systems for detection and analysis of cell-based assays in the field of immuno-oncology, cell/gene therapy, regenerative medicine, protein science, and microbiology. Leo’s primary focus is on cell counting and education for image-based technologies.
Practical Application of ISO Cell Counting Standards to Improve the Quality of Cell Counting Measurements
Biological samples range in complexities and require various considerations, formulations, and bioprocessing steps depending on intended utilization. As there are no ground truth reference materials for live cells, determining the accuracy of cell counting becomes challenging. Therefore, to increase the confidence of cell counting results, following the ISO cell counting standards is necessary to ensure the appropriate cell counting methods are selected and evaluated.
