The CDB Microscopy Core is the primary light microscopy facility for researchers at the Perelman School of Medicine at The University of Pennsylvania. We are also open to the entire University of Pennsylvania community as well as to CHOP, Wistar, and other local institutions. While our emphasis is on confocal and related technologies, our aim is to provide personalized assistance on all aspects of imaging, from tips on sample preparation to training on one of our microscopes to processing and analysis of image data.

"Imagine you had access to an imaging system that could deliver optical sections of large samples, with virtually no phototoxicity or bleaching and with high temporal resolution.
That is exactly what Lightsheet Z.1 from ZEISS does. The unique Multiview light sheet fluorescence microscope allows you to record the development of large, living samples and gently image them to deliver exceptionally high information content.
It is also fast: Lightsheet Z.1 is the tool you need to get optical sections at unprecedented speed. Acquire images of your whole sample volume at sub-cellular resolution – in a fraction of the time it takes using other techniques."
"Core staff members are available for consultation on design of imaging experiments."
"You bring prepared samples and a Core staff member acquires the images for you. To book an assisted session, contact Andrea or Jasmine via email. Assisted sessions must take place during regular weekday hours (9:00am - 6:00pm, M-F). Recommended for users new to confocal or who need confocal images only occasionally."
"Users who have completed their hands-on training may book their own sessions through our online reservation system and work independently on any of our microscopes. Unassisted sessions can take place anytime, weekdays or weekends. Recommended for users who need to use our microscopes on a routine basis. For more information about our training program please read this page.
Training: No charge for mandatory pre -training lecture. Hands-on training is $250 per person; this includes credit for the first three hours of unassisted use (unassisted sessions must take place within one month of hands-on training in order to qualify)."

"Fiji is an image processing package. It can be described as a distribution of ImageJ (and soon ImageJ2) together with Java, Java 3D and a lot of plugins organized into a coherent menu structure. Fiji compares to ImageJ as Ubuntu compares to Linux."
GIMP is an "open-source substitute for Adobe Photoshop and Illustrator."
"iVision‐Mac is image acquisition, processing, measurement, and analysis software. iVision‐Mac directly supports the acquisition of images and time-lapse series. Sophisticated imaging processes or even simple routines can be automated down to the push of a single button through the use of the intuitive scripting tool. There is no need to learn Visual Basic or other programming languages when you want to automate your imaging routines. Also, fully integrated extensions easily automate microscope control by driving motorized microscope hardware.
Using spatially calibrated images with the automated measurement tools, scientists can quickly and easily perform dozens of image processing tasks. The resulting data can be saved in iVision‐Mac, or opened in a spreadsheet program such as Excel for further analysis. User definable plots and histograms are also included to present the data as desired. iVision‐Mac also includes densitometry measurements that can be used to plot an analysis such as mean intensity over time. iVision‐Mac supports the measurement of individual objects, regions of interest, and entire images. iVision‐Mac performs batch analysis of images and sequences using file lists and indexed files."
"MetaMorph Software provides all the tools needed to perform meaningful analysis of acquired images. Common tools for thresholding, filtering, and feature extraction are included as one would expect. However, MetaMorph Software provides other more sophisticated tools such as the integrated morphometry analysis (IMA) module. IMA allows objects to be measured and separated into user-definable classes, based on any combination of measured morphometric parameters, such as shape, size, or optical density. A point-and-click interface, linking images and spreadsheet results, makes it easy to choose representative objects for classification and measurement.
MetaMorph Software also offers many user-friendly application modules for biology-specific analysis such as cell signaling, cell counting, and protein expression. Each application module features a dedicated dialog box with intuitive setting selections, improved segmentation through adaptation to local content, as well as both field and cell-by-cell data logging. After analysis is complete, users can interactively view tabular and image results side by side for their cellular imaging application."
