Zeiss Axio Observer 7 with Apotome III Microscope

This is a multi-function, motorized inverted microscope that includes a brightfield color camera and a 14bit greyscale fluorescence camera. The addition of the Apotome III attachment allows this microscope to give crisp "confocal-like" z-stack images of thinner samples. Thinner means out to approximately 20um in thickness, making this microscope suitable for samples such as: cells on a coverslip, paraffin and standard cryostat sections.

How does this microscope create "confocal-like" images? - The Apotome III projects a grid structure into the focal plane of the specimen, then moves it into different positions using a scanning mechanism. At each grid position, the Apotome III automatically acquires a digital image. The system processes all images into one optical section with improved contrast and increased resolution using a patented algorithm. The resulting image is free from grid structures. (SOURCE: Zeiss) Deconvolution software is available to further improve the image quality of the Apotome images.

Features:

  • AI sample finder - using a unique contrasting method, the microscope can find multiple wells in a plate, unstained sections on a slide, or locate the edges of a coverslip . Very useful for setting things up to scan multiple areas or large area scanning of tissue that's otherwise difficult to see by eye.
  • Colibri 7 LED illuminator allows for 7 specific excitation wavelengths (including a near-IR wavelength). With just two multi-band filter sets, switching between channels is significantly faster than microscopes using filter cubes, making tile scanning in fluorescence much faster. Due to spectral overlap issues, we should be able to capture up to 5 channels in regular widefield fluorescence and 4 channels with the Apotome III (which does not work with near-IR wavelengths). To see how your dyes might work with this system, see our configuration at FPbase.
  • Capable of color brightfield imaging (e.g., histology stained slides), Differential Interference Contrast (DIC, e.g., unstained cells), simple Polarized light imaging (crossed linear polarizers, e.g., Picrosirious red staining), and multiple channels of fluorescence as well as combinations of any of these imaging modes.

Specifications

  • Objective lenses: 5x/0.16NA dry, 10x/0.45NA dry, 20x/0.8NA dry, 40x/1.3NA oil, 63x/1.4NA oil (a 40x/0.95NA dry objective with coverslip correction is available upon advance request)

Core Facility Pilot Program (August 3, 2023 deadline)

Date of publication

The RII Core Facilities Pilot Program is designed to support three key types of activity within the RII-managed core facilities. Each CFPP proposal will be evaluated on scientific merit and feasibility, and should focus on one or more of the following activity types:

  1. The development of new methods or techniques that would extend the standard operating procedures and capabilities of RII-managed core facilities and potentially impact multiple UA researchers. 
  2. The acquisition of preliminary data needed for extramural proposals. Successful projects will result in at least one new extramural research proposal. 
  3. The technical training of students conducting research under existing extramural funding. Proposals to train students from traditionally marginalized groups will be given funding priority.

Most awards will be capped at approximately $10,000, although well-justified projects may be awarded funding above this level.

List of eligible facilities:

  1. Analytical and Biological Mass Spectrometry
  2. Flow Cytometry and Human Immune Monitoring Shared Resource (BD LSR, BD, FACSARIA, BD Canto)
  3. Functional Genomics Core
  4. Imaging Cores - Electron
  5. Imaging Cores - Optical
  6. Machining and Welding Center
  7. Micro/Nano Fabrication Center
  8. Translational Bioimaging Resource
  9. University of Arizona Genetics Core
  10. BIO5 Genetically Engineered Mouse Models (GEMM) Core
  11. Arizona Genomics Institute

Proposals are due: AUGUST 2, 2023  | 5:00p

Imaging Cores - Optical receives 2022 EEF funds from RII to purchase Zeiss Apotome microscope for LSN

Date of publication

The RII Imaging Cores - Optical, in collaboration with the core's Faculty Research Advisory Committee (FRAC), was awarded internal equipment enhancement funds for their proposal to purchase a Zeiss Axio Observer 7 widefield microscope with an Apotome III attachment that gives confocal-like resolution and optical sectioning capabilities in samples up to about 20um in thickness. The Faculty lead on the proposal was Dr. Helena Morrison (College of Nursing) , along with co-PIs Dr. Erica Eggers and Dr. Art Rigel (both from the College of Medicine).

This new instrument will run using the ZEN software, which is familiar to the users of many of the other instruments in the core facility. It is a fully motorized widefield system and should enable the capture of up to 5 colors (4 visible light, 1 near-IR) in fluorescence widefield mode, and 4 colors using the Apotome.

The microscope will be located in Life Sciences North and expected installation is sometime in May 2023.

More information on the Apotome.

Microscopy Month

Date of publication

During the period between mid-August to mid-September all four of the major optical microscope vendors will be doing on-site demonstrations of very well equipped research-grade microscopes.

Why?

The managers of the RII Imaging Cores – Optical are evaluating microscopes, along with our faculty oversight committee, for a planned application to the UA’s equipment enhancement fund for core facilities, due September 28, 2022. The microscope would go in our core facility, probably in Life Sciences North. 

We are looking for a fully-motorized, computer-controlled widefield microscope with a color camera and a high-end fluorescence camera. The microscope would be similar to the popular Leica DMI6000 that we already have, with a few distinctives. The rationale for a second, somewhat similar, microscope is to avoid potentially overloading the schedule of existing Leica.

  • Stereology software – A recent faculty hire has been promised stereology software from MBF Biosciences to be installed either on the DMI6000 or possibly on the proposed new microscope. The new software controls the microscope and cameras directly, acquiring images and performing the analyses on those images in real time. Stereology is an unbiased form of image analysis that relies on the math found in geometry and statistics. The technique is often used by brain and lung researchers, but it is not limited to those organs. For more information, see: https://www.stereology.info/stereology/
  • Confocal-like images – We will be evaluating three microscopes with deconvolution software and one with a hardware structured illumination approach to obtaining crisp fluorescence images. Both approaches are robust and have been used in publications for many years. One of our goals is to provide a way for UAHS labs with thin samples (e.g., paraffin sectioned tissue or cultured cells) to obtain confocal-like fluorescence images without needing to travel to the very popular confocal microscope found in the Marley facility.

For the latest information on the schedule and the vendors that are coming, please see the Microscopy Month page on the Microscopy Alliance website.
