Immunophenotyping
Immunophenotyping is the characterization of cells based on the expression of genes and combinations of genes. Flow cytometry can be used to quantify the number and proportion of specific cell types in a heterogeneous mixture, by examining the expression of proteins often expressed on the surface of cells. This information can then be used to diagnose and classify diseases, monitor the effectiveness of treatment, and study the immune system.
Cell Sorting
Flow cytometry may be used to separate and sort cells based on various detectable characteristics, which has many uses in research. Some examples of applications of cell sorting include: purifying transfected cells based on the expression of a fluorescent reporter gene and separating single cells prior to single cell RNAseq.
Cell Proliferation Assays
Cell proliferation assays measure the often rapid expansion of a cell population. Important in homeostasis, it is also used to measure the activation of T cells that results in rapid clonal expansion.
Cell Cycle Analysis
Cell cycle analysis is the process of measuring the DNA content of cells in order to determine stages of the cell cycle. It is used in a variety of applications, such as the study of cancer, the development of new drugs, and the monitoring of treatment response.
Apoptosis
Apoptosis or programmed cell death is a complex but fundamental cellular process important in the development, growth, and homeostasis of multicellular organisms. It is essential for removing old, damaged, or infected cells.
Transfection Efficiency
Transfection efficiency is the percentage of cells that take up and express a foreign gene. It is an important parameter in molecular biology, as it determines the success of gene transfer experiments.
Therapeutics development, antibody screening, and biomarker discovery demand maximal productivity to reduce time-to-results, which can greatly benefit from high-throughput, high parametric flow analysis interfaced with robotic automation.
