1. 0 ImageTool USER MANUAL Duolink ImageTool is an image analysis software that objectively quantifies PLA signals and cell nuclei Table of Contents Product InformatiOn ss cria imc nin 1 06 OM aasta amm eta alin Aaa Start up Software Installation sss Fluorescence Analysis Brightfeld Ari alysiS cerneret as SUP DOME Duolink ImageTool 4 Product Information USB FLASH DRIVE The USB flash drive contains the installation file for Duolink ImageTool The USB flash drive has a 16 GB storage capacity to facilitate image transfer or storage of analyzed projects NOTE The USB flash drive works as a software protection key All files and folders on the device at delivery are therefore vital The USB flash drive must be plugged into the computer to run the software in full mode IMAGE IMPORT The import function allows direct image import from four well known microscope brands Zeiss zvi Leica lif Olympus oif and Nikon ics It is also possible to import jpg and tiff images grayscale and color SOFTWARE UPDATE The software automatically checks monthly for new updates Manual checks can also be done under the Help menu REQUIREMENTS Duolink ImageTool can be installed and used on computers with the following 32 bit or 64 bit operating systems Windows XP Windows Vista or2. Windows 7 Duolink Image Tool 5 Image Acquisition The PLA signal is recognized as a spot an individual signal is of sub micrometer size The result from a Duolink experiment is typically a number of discrete PLA signals in various locations of the studied cell or tissue samples If images are acquired in a single focal plane several signals can be either above or below the current focus To detect all PLA signals it is thus necessary to acquire images at several focal planes through the thickness of the sample However you may acquire images with a single focal plane as long as all images to be compared are acquired with similar focus within the sample If the primary antibodies are not properly titrated the density of signals may be so high that the signals merge Duolink ImageTool can not quantify regions of merged signals only separable signals can be counted For images taken with fluorescence microscopy a quality control function displays a warning if signals are merged If nuclei are densely packed or tissue sections are thick single cell measurements may be inaccurate Cell detection is easily verified by visual inspection of the cell outlines Duolink ImageTool 7 Start up Software Installation Plug in the USB flash drive It works as a security key and must be plugged in to run the software in full mode Start the Setup file and install the software Duolink ImageTool uses a project file structure Create a
