Flow Cytometry
Flow Cytometry — A technique for counting, examining, and sorting cells by passing them through a laser beam, used with fluorescent peptide probes.
What Is Flow Cytometry?
Flow cytometry is a technique that analyzes individual cells in a fluid stream by passing them through one or more laser beams. It measures physical characteristics (size, granularity) and fluorescence from bound antibodies or dyes, enabling identification and quantification of cell populations. In peptide research, flow cytometry measures peptide effects on immune cell populations, apoptosis, cell cycle, and receptor expression.
Peptide Research Applications
- Immune phenotyping: Measure T cell, B cell, NK cell, and macrophage populations after peptide treatment
- Receptor expression: Quantify receptor surface density changes upon peptide stimulation
- Apoptosis: Annexin V/PI staining detects peptide-induced cell death
- Intracellular cytokines: Measure cytokine production at the single-cell level
- Peptide uptake: Track fluorescently labeled CPP internalization
