2009 is the year of the 40th anniversary since the introduction of the first global flow cytometer based on fluorescence, the ICP 11.

Currently, the German biotechnology company Partec celebrates anniversary in Saxonia State Wackerbarth Vineyard Castle near Dresden. For the festive ceremony, the director Roland Göhde receive 100 guests from the scientific, economic and political.

In 1968 cytometry based on fluorescence was developed by Prof. Dr. Wolfgang Göhde and the University in Muenster and patented that same year (German patent application DE1815352). Currently, flow cytometry has evolved as a standard tool for a wide range of applications in health, microbiology, Agrociencia, aquaculture and quality control in industrial fields.

The flow cytometry-based fluorescence is a standard method for the rapid and automated cell analysis and cell enumeration procedures. Using the most modern optoelectronics, particles and cells are detected in small size, even in the nanometer range. The cells are sold with specific reagents and excited by one or more lasers, subsequently recording the fluorescence signal emitted. With the data obtained, the cells are characterized, classified, quantified and ranked. For monitoring HIV antiretroviral therapy in patients with AIDS, it is necessary to determine the number of CD4 cells.
