Enhancing cell line characterization with flow cytometry services provides a comprehensive and advanced approach to analyzing cellular properties and behaviors. At our facility, we offer specialized flow cytometry services tailored to enhance the understanding of cell lines in research. Our services include (but are not limited to) immunophenotyping to identify cell surface markers, intracellular staining for protein expression analysis, cell cycle analysis to assess proliferation rates, karyotyping, and apoptosis assays to measure cell viability and health.
Flow cytometry is a versatile and powerful tool used in a wide range of applications for characterizing cell populations. Key applications of flow cytometry in cell characterization include:
1. Immunophenotyping
- Cell Surface Markers: Identification and quantification of specific cell surface markers to characterize different cell types within a mixed population.
- Immune Cells: Commonly used to characterize various immune cell subsets, such as T cells, B cells, natural killer (NK) cells, and dendritic cells.
2. Cell Cycle Analysis
- DNA Content: Measurement of DNA content within cells to determine the distribution of cells across different phases of the cell cycle (G0/G1, S, G2/M).
- Proliferation Studies: Helps in studying cell proliferation, growth rates, and the effects of drugs on the cell cycle.
3. Cell Viability
- Annexin V Staining: Detection of phosphatidylserine exposure on the cell surface, an early marker of apoptosis.
- Caspase Activation: Measurement of caspase activity to monitor the execution phase of apoptosis.
- Live/Dead Assays: Use of dyes to distinguish between live, apoptotic, and necrotic cells.
4. Intracellular Cytokine Staining
- Cytokine Production: Detection and quantification of intracellular cytokines to study immune responses and cell signaling pathways.
- Functional Analysis: Assessment of cellular function and activity, such as T-cell activation and differentiation.
5. Genomic and Proteomic Studies
- Protein Expression: Quantification of intracellular and cell surface protein levels using fluorescently labeled antibodies.
- Gene Expression: Analysis of mRNA levels through flow cytometry-based techniques, such as flow-FISH (fluorescent in situ hybridization).
6. Stem Cell Characterization
- Marker Expression: Identification and isolation of stem cells based on specific surface markers.
- Differentiation Status: Monitoring of stem cell differentiation into various lineages by detecting lineage-specific markers.
7. Microbial and Pathogen Detection
- Bacterial Characterization: Identification and characterization of bacterial species in samples.
- Viral Infections: Detection of viral infections and monitoring of virus-infected cells using specific markers.
8. Drug Screening and Toxicology
- Drug Effects: Evaluation of the effects of new drug candidates on cell viability, proliferation, and apoptosis.
- Toxicity Studies: Assessment of the cytotoxic effects on various cell types.
9. Functional Assays
- Calcium Flux Assays: Measurement of intracellular calcium levels to study cell signaling and activation.
- Phagocytosis: Assessment of phagocytic activity of immune cells by measuring the uptake of fluorescently labeled particles.
10. Epigenetic Studies
- Histone Modification: Detection of specific histone modifications to study epigenetic changes.
- DNA Methylation: Analysis of DNA methylation patterns using flow cytometry-based techniques.
