Flow cytometry is an appealing technique because it enables users to analyze multiple cell types in a single experiment. In the early days of flow cytometry, when cytometers had one or two lasers, and only a limited number of fluorescent probes existed, complex staining panels may have had only four colors.Read the full article »
Flow cytometry is a well-established approach used in numerous clinical assays across the globe. But like most assays used in a clinical setting, flow cytometry assays typically need to be validated before they can be used for diagnostic or clinical research purposes.
Assay validation is done to demonstrate that a method is accurate, specific, reproducible and robust over a designated range of measurement. Flow cytometry is considered an analytical method, and according to the FDA, flow cytometry assays need to meet specific analytical method validation criteria. A validated assay can then be used in situations requiring GLP/GCP (good laboratory/clinical practice) compliance, like a clinical trial or routine diagnostic test.Read the full article »
Receptor occupancy (RO) assays are a powerful tool for pharmacokinetic/pharmacodynamic evaluations of candidate drugs and biologics. RO assays can also be used toward dose selection for candidate molecules being evaluated in clinical trials. Flow cytometry-based RO assays are currently being used in many sectors of biopharmaceutical drug development. Consider these five things to know about RO assays if you are planning to use this type of assay in your preclinical research.Read the full article »
