Laboratory of Cytometry

Head: Katarzyna PIWOCKA


The Laboratory of Cytometry has been established in June 2010 to provide state of the art multicolor flow cytometry service. Currently, Laboratory is equipped with the BD FACSCalibur flow cytometer, BD FACSAria cell sorter and iCys scanning cytometer. In 2011 the two new instruments will be established: 2-laser BD FACSCalibur and 4-laser LSR Fortessa cytometer, which allows for high-quality multiparameter/multicolour analysis. The Laboratory of Cytometry provides also a cell culture unit and all necessary laboratory facilities.

More information about laboratory on the web page:

  • Cytometer BD FACSCalibur – equipped in the 488 nm laser and red diode 635 nm
  • Cell sorter BD FACSAria – equipped in the 488 nm, 635 nm lasers and UV lamp
  • Cytometer BD FACSCalibur – equipped in the 488 and 635 nm lasers
  • BD LSR Fortessa Analyser – equipped in the 355 nm, 405 nm, 488 nm and 635 nm lasers


1. The Laboratory provides the core-facility service for investigators from the Nencki Institute and other scientific and R&D institutions;
2. We offer expertise and technical assistance in flow cytometry, cell sorting as well as laser scanning cytometry. We provide the expert consultation for experiment design, fluorochrome selection and data analysis;
3. The Laboratory is involved in the basic research and innovative projects, based on the high-tech flow cytometry applications. Lab members realise own research projects as well as are involved in the colaborative projects with other scientific groups;
4. Education – we organise lectures, training courses and hands-on workshops for beginners and advanced researchers.


  • Immunophenotyping;
  • analysis of apoptosis and viability;
  • analysis of proliferation, cell cycle and mitosis;
  • analysis of DNA damage/breaks;
  • analysis of calcium ions, free radicals production and mitochondrial membrane potential;
  • immunofluorescence of surface and intracellular markers expression;
  • cytokine production;
  • cell sorting;
  • others, designed individually, dependently on needs.
