Haven't heard about optogenetic flow cytometry?



Opto Biolabs' pxONE is an LED illumination device designed to combine optogenetic experiments with flow cytometry. It illuminates cell samples homogenously and an attached water bath keeps the temperature stable. Software control allows easy selection of light intensity and exposure time.

As a result, optogenetic experiments can be analyzed with over 20.000 cells/second at single cell resolution. A plethora of established protocols for flow cytometry (calcium flux analysis, apoptosis, multiparameter analysis, cell population analysis etc.) can now easily be adapted to optogenetics.

The pxONE is compatible with BD LSR II, BD LSR FORTESSA, and Miltenyi MACS Quant Analyzer. Ask us about compatability for other cytometers.


this is how easy it is!

See for yourself how quickly you can assemble the pxONE with your cytometer to start your first optogenetic flow cytometry experiment:

The pxSORT is an LED illumination device suitable for fluorescence activated cell sorting (FACS) machines. This enables the convenient separation of e.g. reacting from non-reacting optogenetic cell populations for further analysis or culture. Contact us if you want to be the first to try!


The pxINC is a cell culture plate illumination device that can illuminate 6-,12- or 24-well plates individually with 2 different wavelenghts. This allows you to create and test various illumination protocols for your cell culture at the same time. Contact us if you want to be the first to try!
