Cytometry and Cell Sorting Units

Cytometry and Cell Sorting Units

Flow cytometry is a cell analysis technique that involves measuring the light scattering and fluorescence characteristics of cells as they pass through a beam of light. Flow cytometry is used in the counting and classification of cells according to their morphological characteristics and presence of biomarkers, as well as in protein engineering. In flow cytometers, cells suspended in a fluid pass through a very thin transparent tube that is hit by a thin beam of laser light. The light transmitted and dispersed by the passage of the cells through the tube is collected by detection devices, allowing to make inferences on size and complexity of the cells. The use of fluorescent molecules allows to analyse the presence of several markers simultaneously. Sorters can also purify populations with specific characteristics into different final fractions while counting the number of cells present in the sample.

This unit aims to:
  • Provide access to equipment specialized in flow cytometry and cell sorting to INiBICA's researchers and external users, while providing technical expertise and training.
  • Provide technical support and advice to INiBICA's research groups or visiting researchers in the fields of design of experiments, selection of markers, acquisition of samples, analysis of cell populations and discussion of the results obtained.
  • Provide isolation of cell populations through "Cell Sorting" technology.
  • Develop new technologies and assess new equipment.
  • Provide training on this technology to users.
