Microscopes & Flow Cytometers

The facility currently houses four optical microscopes: an Andor Dragonfly spinning disk confocal microscope, a Zeiss LSM 510 confocal microscope, an inverted Zeiss AxioObserver fluorescent microscope, and an upright Zeiss AxioImager fluorescent microscope. We also have a BD Fortessa cell analyzer, and a BD FACSAria cell sorter.

View Details About Microscopes

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 microsocpe is able to acuire 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 LSM 510 Microscope.

The Zeiss LSM 510-Meta point scanning confocal microscope is mounted on an inverted microscope base. It currently has six laser excitation lines, two single-channel PMT detectors, and a multispectral detector. With the current laser configuration, UV excitation is not possible on this microscope. Thus, staining protocols with DAPI or Hoechst should be modified for other nuclear stains. The monomeric cyanine nucleic acid stains provide many strong alternatives; TO-PRO 3 is recommended for any protocol with a far-red dye.

Available laser lines (nm):

  • Argon laser: 458, 477, 488, 514
  • DPSS: 561
  • HeNe: 633

Detector 1 emission filters:

  • Short Pass: 685
  • Band Pass: 480-520; 500-530; 500-550

Detector 2 emission filters:

  • Long Pass: 505; 575
  • Band Pass: 500-520; 500-550; 535-590; 575-615; 650-710
Zeiss Axiolmager Microscope.

The Zeiss AxioImager is an upright widefield fluorescent microscope ideal for thin slide mounted samples. In addition to the monochrome camera for fluorescent imaging, this scope also has a color camera ideal for imaging histological sections.

Zeiss AxioObserver Microscope.

The Zeiss AxioObserver is an inverted widefield fluorescent microscope with a custom-built incubation chamber allowing for short-term live cell imaging.

  • A microplate reader (BioTek Synergy HT)
  • A NanoDrop One Spectrophotometer


While the facility does not presently have dedicated analysis computers available to users, there are many freely available data analysis applications that we are happy to help users with as much as we are able.

Image Analysis

ImageJ/FIJI is a free 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.

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.

Cytometry Analysis

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.
