Flow cytometry & Biacore
Flow cytometry (FCS_DSV) is a technique that allows making qualitative and quantitative analysis of single cells. It is a rapid and sensitive technique capable of providing information on eukaryotic as well as prokaryotic cells.
Biomedical and environmental applications include:
- biomedical and environmental applications include:
- immunophenotype determination
- cell cycle and ploidy analysis,
- marker analysis (membrane or cytosolic)
- induction of apoptosis-necrosis,
- analyses of cellular functions (phagocytosis, endocytosis, ROS),
- binding / uptake of drugs;
- mechanism of action of membranolitic substances against gram + bacteria and Gram-
Surface Plasmon Resonance (SPR_DSV) is a high sensitivity technique that allows real-time measurements of biomolecular interactions, without requiring potentially invasive tracers. It can provide qualitative and quantitative information on the interaction selectivity, as well as on binding kinetics and binding affinity (dissociation constants).
It is applicable to the study of:
- interactions between molecules of biological interest (proteins, nucleic acids, carbohydrates, lipids, also with small organic molecules).
- Dissociation constants between a surface immobilized molecule (eg. protein, antibody, nucleic acid) and a molecule in the supernatant (respectively a ligand, antigen or complementary oligonucleotide/binding protein)
- interaction between molecules (eg peptides or proteins) and model biological membranes (liposomes)
The flow cytometry (FCS_DSV) and Biacore (SPR_DSV) Service at the Department of Life Sciences provides skills and tools to Academic and external users. Access to the service is regulated and requires a contribution to support of management/maintenance costs of instruments, as specified in the rates table (see Service Rules), and is charged to the head of the research group that requires this services.
