Huygens Colocalization Analyzer

With unique 3D visualization

Huygens Essential | Huygens Professional

With the Huygens Colocalization Analyzer you can obtain all common colocalization coefficients for 2D and 3D images and time series. The colocalization is also visualized in a map that shows the colocalizing regions. In combination with true Huygens Deconvolution, the Colocalization Analyzer allows for reliable analysis of your images!

Why Huygens?

11 colocalization coefficients available

Pre-processing with Huygens Deconvolution for more reliable analysis

Unique 3D map to visualize regions of colocalization

Object analysis available to investigate local colocalizations

Msp at kinetochore complex | Pearson = 0.458

3D widefield image of a U2OS cell. Inset: Colocalization Analyzer-produced iso-surfaces (yellow) from pixels contributing 8% to the total Pearson colocalization (0.458) between labeled Msp (green) and kinetochore substrate Aurora B (red). Huygens Deconvolution and Chromatic Aberration Correction performed before analysis. Data from Dr. Livio Kleij en Martijn Vroomans, UMC Utrecht, The Netherlands.

Synaptic protein at dendritic spines | Overlap = 0.281

Coloc Analysis Neuron
Colocalization Analyzer-produced colocalization map (left, yellow) shows regions of colocalization between a synaptic protein (green) and a dendrite (red) at the dendritic spine heads. 3D confocal image of brain tissue was deconvolved with Huygens before analysis. Data from dr. Nawal Zabouri and Mariska Willemsen, Netherlands Institute for Neuroscience.

Everything is working smoothly. The colocalisation module is very good, the best I have tested so far.

I previously used ImageJ for Colocalization Analysis, but I actually find Huygens much more convenient and easier to use, moreover, it is much faster and the results are more consistent [..].
