To demonstrate the importance of this facility to research at UB and aid in the procurement of future equipment, we ask users to please acknowledge the Optical Imaging and Analysis Facility in your publications, and to inform the facility director at the time of publication. 

Principle Equipment

The facility currently houses four optical microscopes: an Andor Dragonfly spinning disk confocal microscope, an inverted Zeiss AxioObserver fluorescent microscope, and an upright Zeiss AxioImager fluorescent microscope. We also have a BD Fortessa cell analyzer, a BD FACSAria cell sorter, a ScanCo µ100 microCT, and a PerkinElmer IVIS Lumina LT. 

Andor Dragonfly microscope.

The Andor Dragonfly spinning disk confocal microscope is mounted on an inverted Leica microscope base. This microscope is designed for long-term live-cell imaging, having both temperature and CO2 controls, as well as a focus drift correction system to maintain focus over long periods. Additionally, with the high sensitivity sCMOS camera, fast filter wheel, and piezo stage, this microscope is able to acquire large multi-channel volumetric images very quickly. 

Four available solid state laser lines (nm): 405, 488, 561, 635

Four available emission filters: 420-470, 500-540, 580-605, 640-740

Zeiss AxioObserver Microscope.

The Zeiss AxioObserver is an inverted widefield fluorescent and brightfield microscope for routine imaging of fluorescent or colorimetric slides or plates. 

Available filter sets (links to Zeiss filter specifications): 

Cytek Aurora Spectral Flow Cytometer.

Our Cytek Aurora is a 4-laser system with 48 detection channels distributed across the visible-NiR spectrum. Combined with the spectral unmixing and autofluorescence extraction this allows for 24+ color panel assays with much better separation and resolution than conventional flow cytometers. Since every detection channel is used for all data acquisition, it eliminates the need to pick optimal detectors or match fluorophores to specific bandpass filters, making both panel design and instrument operation easier. It also measures the fluid volume during sample acquisition, allowing for cell density measurements. 

BD FACS Aria cell sorter.

The BD FACSAria Fusion cell sorter is equipped with five lasers and can sort cells into four separate tubes based on up to eighteen fluorescent markers.

Each available laser line has its own set of long-pass (LP) dichroic mirrors and bandpass filters configured for the most commonly used dyes:

The ScanCo µCT 100 is a high-resolution computed-tomography scanner for non-living samples. The scanner is capable of resolutions down to 3.5 µm. The instrument can hold up to 12 sample holders at a time to perform batch scanning. The facility has two of each of the cylindrical sample holders with the following internal diameters (in mm): 8, 12, 17, 32, 46, 71, 84, 99. 

The PerkinElmer IVIS Lumina LT is a live animal topographic imager capable of imaging most small rodents, or small objects. This system performs best when imaging luminescent transgenic rodents, but is also capable of fluorescent imaging. For fluorescence, the IVIS has ten 30 nm bandwidth excitation filters covering the full spectrum from 415 nm to 760 nm, and four emission filters:

  • GFP (545/60)
  • DsRed (612/75)
  • Cy5.5 (732/75)
  • ICG (842/65)

Any prospective user of the IVIS instrument must be listed as personnel on an approved IACUC protocol. This IACUC protocol must also contain the standard procedure for the IVIS imager. This information will be verified by the facility director prior to IVIS use.

Additional Equipment

The facility currently has:

The Azure Cielo 6 is a six channel qPCR instrument. This instrument is only compatible with semi-skirted or no-skirt low-profile 96 well PCR plates. Full-skirted or high-profile plates will not fit.

If there is any other software that you would like installed on the analysis computer you may put in a request with the facility director.

Additionally, there are many freely available data analysis applications that we are happy to help users with as much as we are able.

ImageJ/FIJI is a free, open-source software package for analyzing 2D or 3D microscopy images. While not as intuitive as some of the available commercial software, it does offer extensive documentation and a large plugin database, making it a very powerful image analysis tool. It is also very versatile and can work on nearly any type of image data.

CellProfiler is another free, open-source image analysis package designed to easily automate the processing and analysis of cell images.

QuPath is an open source package designed for the analysis of whole slide images from slide scanners. However, it can work on traditional microscopy images and features powerful trainable pixel and object classifiers.

Vaa3D is a free, open-source image analysis platform designed specifically for 3D datasets, and is particularly well suited to 3D data visualization.

ZEN lite is a basic image processing only version of their ZEN acquisition software. The movie exporter of ZEN lite can generate smaller sized, higher-resolution videos than other freely available image analysis software.

Floreada is a free online web app for flow cytometry analysis. While still early in development, this web app is very easy to use and provides many of the most common features used in cytometry data analysis. You can view their YouTube channel for tutorial videos.

FCSalyzer is a free open-source java application for analyzing flow cytometry data. While this software is still in its early stages, it already offers most of the processing and analysis capabilities as the major software packages. They also have several tutorial videos available.

Flowing Software is a freely available application for flow cytometry data. While a bit more complex than its paid counterparts, it has a number of tutorial videos to get users started. This software does not work on FCS 3.1 files, only 2.0 and 3.0. Additionally, the development of Flowing Software has stopped, and the source code was never released, thus there will likely be no future updates.

FlowJo and FCSExpress are the most commonly employed paid flow cytometry applications available. Both are powerful, user-friendly data analysis tools that are more likely to receive regular updates, and will provide support to their users.

Micro CT

To import mgHA/ccm calibrated DICOM files from the ScanCo100 microCT into Fiji, you will need to do the following:

  1. Installation:
    1. Download Fiji and extract it to a location where you have write privileges, such as your documents folder.
    2. Open Fiji and go to Help > Update... Then click "Manage Update Sites" and "Add Unlisted Site". For the new update site, put in: 
      1. Name:  ScanCo100 Import
      2. URL: https://sites.imagej.net/UBoiaf-microct/ 
    3. Make sure your new update site is set as "Active" (the checkbox is checked), then click "Apply and Close" and "Apply Changes". Restart Fiji.
  2. Data Import:
    1. Make sure that the DICOM sequence you want to open is in a folder containing only those *.dcm files.
    2. Open Fiji and go to Plugins > MicroCT > ScanCo 100 import - Calibrated Data. Navigate to the folder containing your DICOM files, select the first file only, and click "Open". The plugin will use pattern recognition to open the entire sequence. 
    3. Once the image is open, intensity measurements will be reported in calibrated units. The calibration equation can be viewed by going to Analyze > Calibrate, checking the "Show plot" box, and clicking "OK." 
    4. For further discussion on utilizing calibrated data within Fiji, please schedule a consultation with facility staff.
