Final answer:
The focus assay can be done to identify specific subsets of cells using flow cytometry and immunofluorescence techniques. Flow cytometry is an automated cell-counting system that detects fluorescing cells as they pass through a narrow tube one cell at a time. Immunofluorescence can be used to label cells with fluorescently labeled antibodies and identify specific cell types based on the fluorescence intensitythe correct answer.specific subsets
Step-by-step explanation:
The focus assay can be done to identify specific subsets of cells using flow cytometry and immunofluorescence techniques. Flow cytometry is an automated cell-counting system that detects fluorescing cells as they pass through a narrow tube one cell at a time. Immunofluorescence can be used to label cells with fluorescently labeled antibodies and identify specific cell types based on the fluorescence intensity. These techniques are commonly used in research to study and sort different populations of cells.
