Light Microscopy Core
In light of the stay-at-home advistory, there is much that can be done with existing data, project planning, paper writing, etc. And I am here to assist with all of those things and more…so please do not hesitate to get in touch.
- Data Analysis
- Ten of our PCs have been temporarily converted to analysis workstations that can be accessed remotely making 14 now available. All can perform basic image analysis, and GA2 is available on many machines, GA3 is only currently available on WS1 and WS2 (WS3 soon – Nikon is mailing a demo key). To access any of the PCs remotely, I simply need to add you to an approved list (which I have to do manually, so please let me know if you’d like to have access – I will then provide instructions.)
- Daily Analysis Workshops/Office Hours – M-F, 10-12
- I will be online and free to help you with any type of image analysis you have. Email ahead if possible so I can provide you with simple remote access to a workstation.
- Data Access
- If you are having any trouble connecting to the X-drive via your browser, please let me know. To access X-drive from anywhere in the world, simply point a browser to ials-ds.synology.me (you may or may not need a UMass VPN to gain access from off-campus).
- If you have neglected to move your data from the microscope PC, let me know and I can move it for you. No need to come to the LMF physically.
- Webinars on various topics ranging from basic thresholding, segmentation, automated analysis, and (hopefully) machine learning will be coming soon. As well as collaborating with Nikon to provide some remote sessions. Please let me know what you would like to learn about or gain a deeper understanding of. Watch slack for announcements.
Located on the 5th floor in the Life Science Laboratories the Light Microscopy facility provides powerful resources for imaging model organisms, tissue, cells, biomaterials, and artificial structures and houses state-of-the-art equipment including almost every light microscopy imaging modality currently available. Cell culture facilities are also available as well as other routine needs for biological imaging. This facility is one of a few designated Nikon Centers of Excellence providing a unique opportunity for training, demonstration, instrument development, and research.
The facility accepts samples and will perform requested analysis. We offer training to users to conduct experimentation for use on a fee for service basis to both internal and external researchers, academic or industry based. Following an initial consultation, covering experimental parameters training and access is arranged through the director.
The benefits of working with Nikon as an industry collaborator are that UMass Light Microscopy Facility users receive formal and informal training from Nikon engineers, frequent on-site technical support, access to new hardware and software technology, and assistance with cutting-edge experimental set ups.
A1R-SIMe: Nikon A1 Resonant Scanning Confocal with Structured Illumination Super-Resolution

A1SP: Nikon A1 Spectral Detector Confocal with FLIM Module
This microscope is great for fixed samples and is especially useful when experimenters may have overlapping emissions from fluorophores or autofluorescence. The 32-channel spectral detector can be implemented with the click of a button and allows for 32 x 2.5 – 10nm bins of fluorescence identification.

A1MP: Nikon A1 Resonant Scanning Multi-Photon Confocal
This microscope is an upright, manual microscope that is suited for in vivo, intravital imaging as well as imaging in and through thick tissues and samples. It uses a tunable infrared pulsed laser to excite fluorophores at the focal volume and features a resonance scanner that can image very quickly along with a fast moving piezo nosepiece. We also have visible lasers for standard upright confocal microscopy.
- Objectives: 25x extremely long working distance (upright)

HCA: Nikon with High Content Analysis
This microscope is truly amazing for its ability to collect and automatically
analyze data from live or fixed samples. The intuitive and adaptive software can be programed to count cells, monitor growth, take high-resolution pictures when a certain feature is found, scan slides, scan multi-well plates, etc. A robot can even load your multi-well plates. It has two imaging paths; wide-field and spinning disk. When it is done, you can have the microscope send you a text message that contains any key variables that you need to know right away.

This also has the option to change not only the TIRF angle with the click of a button, but also the direction of the laser entering the back aperture of the objective.
- Objectives: 20x, 60x TIRF, 100 TIRF (HP)
- Laser lines: 405, 488, 561, 640nm

Training for new users consists of:
- lab safety training,
- operation of the instrument and associated software,
- use of data analysis software,
- exporting or presenting data,
- clean up and shutdown of the instrumentation.
Once the training is complete, researchers may schedule their experiments through the director of Light Microscopy (James Chambers) or online through FOM (Facilities Online Manager) at fom.umass.edu/fom
Training generally consists of 2-4 hours per new user and depends on the users previous microscopy experience. All are welcome, even if you have never used a microscope!
Training #1 can be accomplished with 1-4 people and consists of a demonstration of the microscope hardware and software, discussions of light paths, digital image acquisition, saturation, and features of the microscope.
Training #2 is one-on-one and usually is a brief refresher of training #1 followed by the new user on the microscope acquiring images of a facility-provided sample. Advanced users can bring their own samples.
Training #3+ is one-on-one and is the time for the user to use the microscope for their samples. The Trainer will be there to make suggestions/corrections and to be sure the Trainee is going to be able to acquire the data that she/he needs for the project.
Because all of our imaging microscopes run the same software, NIS-Elements, the training for one microscope is transferable to all of the other microscopes.
The Light Microscope Facility offers free advanced training sessions. Be sure to be on the Facility Online Manager list to be alerted to these free offering as well as free “pilot data days.”
- When you have questions about anything, ask the director James Chambers.
- Treat all equipment with respect.
- Do not rush when using the equipment as this leads to breakage/damage that you and your PI will be responsible for replacing.
- Use your allotted time and finish on time when someone is on after you.
- If you know you will not use your reservation, cancel it ASAP.
- Acknowledge use of UMass IALS LMF in all publications. Please use some variant of: “The microscopy data was gathered in the Light Microscopy Facility and Nikon Center of Excellence at the Institute for Applied Life Sciences, UMass Amherst with support from the Massachusetts Life Sciences Center.”
- Adhere to the EH&S-approved live cell standard operating procedure when using live samples.
- No liquids on the microscope air table.
- You are responsible for your data – this means that you should arrange for moving it and backing it up. We will do our best to back it up and preserve it, but it is ultimately the user’s responsibility.
