Hello,
I would ask for some advices for analyzing my data with ImageJ. Shortly what I did is immunofluorecent labeling of human Glucocorticoid receptor in peripheral white blood cells.My aim is to study the temporal localization of the receptor-(GR shuttling between nucleus and cytoplasm within the time). Techinically on 10 wells slides I stained white blood cells with Cy3 conjugated Ab for the Glucocorticoid receptor and Dapi for the nucleus. I am trying to find an ImageJ plugin that can help me automatically to choose only the lymphocytes excluding the granulocytes from my pictures and to measure % of the colocalization of the red and the blue signal . I used Object counter 3D plug in for segmentation and determination of the cetroids and intensity centers. After calculation it gives me their respective coordinates x,y,z.I dont know how to use these coordinates to calculate the colocalization I also wonder whether this is the best plugin for the analysis of my data. I read about this Vector method as well but it is considered for a method obtaining a first estimation of colocalization. Thank you very much for your assistance in advance!

Try the JACoP plugin which allows for thresholding of the images prior to calculating the colocalization. This will only work however if your structures of interest exhibit an intensity that is measurably different than the background signals.

Dear Slavena,
As John O ponts out the JACoP plugin is nice, and implements some good methods. In the Fiji distro of imageJ found at http://pacific.mpi-cbg.de Fiji - is just ImageJ (Batteries Included) you will find 2 coloc plugins in the analyze menu: Colocalization threshold - does auto thresholding as per Costes et al, and coloc map and statistics as per Manders et al etc. . Colocalization test - statistical significance of results - as per Costes These two plugins are updated and maintained as best we can (we just fixed a bug in the Rcoloc calculation) ... but at the same time we are already designing and building the next generation coloc tool for imageJ which we hope will be even more simple to understand and easier to use than the JACoP plugin. If you have a wish list for that, just tell us. For a tutorial on how to use these plugins and what to watch out for see http://pacific.mpi-cbg.de/wiki/index.php/Colocalization_Analysis any questions, just ask. cheers Dan On Jul 3, 2010, at 6:00 AM, IMAGEJ automatic digest system wrote: > Date: Fri, 2 Jul 2010 15:04:02 +0200 > From: Slavena Trifonova <[hidden email]> > Subject: Colocalization plugins > > Hello, > > =20 > > I would ask for some advices for analyzing my data with ImageJ.

Dear All,
Thank you very much for your replies,I am a beginner in this field. I used JaCoP manual and tried it on images but still have some questions using this colocalization measurement plugin. I would really appreciate any help. To analyze the colocalization of the blue and the red signal which refer to Cy3 for Glucocorticoid receptor and Dapi for nucleus in lymphocytes I focused on objects based analysis.I choose to work on centre to centre distances suspecting that the cells are not close to the optical resolution. I dont know which picture format I have to use the original file-zvi or it can be a tif file. I have also some difficulties in setting up the three tabs that appear on the screen using JaCoP. First I dont know how to adjust the threshold of the two images. Second the xy and z (nm) calib -where shall I take this numbers from and what NA means-it is not pointed out anywhere. Another issue is how to measure the particle size with imageJ in order to filter and select only the small lymphocytes excluding the big granulocytes? Thank you very much for your help in advance.
