Phenotypic Assays
Assays that quantify disease phenotype changes in cells require no prior knowledge of disease mechanism of action. A good example of this is in the field of oncology, where uncontrolled cell proliferation is a hallmark of cancer and can be used as the basis for a phenotypic assay. Cytation™ and Lionheart™ can quantify many types of phenotype change, such as counting cells by either fluorescence or brightfield microscopy in the case of cell proliferation. Many other phenotypes can be quantified based on the use of specific fluorescent probes, such as those for oxidative stress, hypoxia, apoptosis, translocation, etc and the image analysis capabilities of Gen5™ Image Prime that provide dual masking capabilities and sub-population analyses based on a wide range of calculated metrics.
