About the Platform

What is Flow Cytometry?

Flow cytometry is a powerful tool used in biology to analyse properties of individual cells and particles in a fluid suspension. 

As the cells or particles flow through the system, they pass through lasers that excite fluorescent dyes and labels. The resulting fluorescence is detected and can be analysed to provide information about the characteristics of each individual cell or particle.

Flow cytometry is particularly useful for analysing large numbers of cells or particles quickly and accurately at a single cell level. It can be used to quantify a wide range of properties; such as relative size and complexity, as well as the presence or absence of specific surface markers or intracellular proteins. 

It is a versatile tool that has revolutionised our ability to study and understand individual cells, and has led to many important discoveries in the fields of biology and medicine.

Technologies and Approach

The SIgN Flow Cytometry Platform is a well-established platform, with a comprehensive fleet of analysers and sorters supported by dedicated technical support staff that can provide sorting services, wet-lab training, consultation services, and execute service project agreements. Our staff can provide guidance at each experimental stage, from study design, processing and staining protocols, to cell sorting and data interpretation. One of our operators is Specialist in Cytometry (SCYM(ASCP)CM) certified, a unique certification dedicated to flow cytometry staff. The SIgN Flow Cytometry Platform can achieve high-throughput deep cellular phenotyping analysis with high-end conventional, spectral flow (Figure 1) and small particle-enabled (Figure 2) flow analysers and sorters. These cutting-edge technologies represent the modern advancements in the field of flow cytometry and enable world-class research to be carried out in the platform.
