Olympus FV3000 demo at the Methodist Research Institute

fv3000-2.2

On Monday 8/15/16 I tested out Olympus’ latest confocal microscope. The biggest change is in the software package, which allows for greater flexibility and customization in your scan settings. I had the chance to try out some types of objectives that we don’t currently have.

vasa-ovary-2x

This is a 3-channel image of a Drosophila ovary taken with a 2x objective. The detail is very good- you can clearly see the nuclei in the mid-stage egg chambers. This wide view makes an excellent roadmap for finding points of interest to zoom in on: click on the region, and the motorized stage will place it in the center of the field of view. Then you can switch to the oil objectives. The slide holder allows you the room to put oil on an objective without having to remove your slide- very convenient!

vasa-ovary-100x-1-all

This is a very closeup image of a germarium/ early stage egg chambers using the 100x oil objective and a zoom of 1.5.

vasa-ovary-60x-silicone-1-all hts-ovary-60x-silicone-1-all

These germaria images were taken using the 60x silicon oil objective and a zoom factor of 4. This type of objective is ideal for thicker specimens mounted in liquid media (in this case Vectashield) because the silicon oil has a lower refractive index (1.4) which is a closer match to the biological materials/ mounting medium. (The first image has 33 z-sections at 0.43 micron thickness for a total thickness of 14.19 microns, and the second has 44 slices of 0.46 micron each for a total of 20.24 microns thickness.)

Thank you to Erin Kelleher for providing specimens for the test drive!!

Coming in the Spring 2017 Semester:

“The Poetics of Microscopy”

The BBIC will be collaborating with the English Department on a creative writing project about the process of science. Any BBIC user who is interested is welcome to participate. More details to follow in the Fall 2016 Semester.

OLYMPUS STAGETOP INCUBATOR DEMO: March 15-April 3, 2016

demo1a

We have an INU stagetop incubator on loan for the next 2 weeks. This system fits into the stage of the Olympus FV1000 and allows you to control temperature and CO2 levels to maintain live cells for observation via confocal microscopy. We have stage inserts for well plates, well slides, and 35 mm dishes (make sure they have glass bottoms designed for confocal use).

Science and Art at the Blaffer Gallery

“Janet Biggs: Echo of the Unknown” opens Friday, Jan 16,2015, 6pm, at the Blaffer Art Gallery. This work explores role of memory in the construction of identity, and the effects of Alzheimer’s disease. Part of the exhibit features images taken by Craig Vollert (Ericksen Lab) on the BBIC’s Leica SP8.

Optical Methods Course (BIOL6222)

optical-methods-in-cell-biology_2015

Additional BioStation Training

Ned will return Jan 13-14. Anyone interested in using the BioStation may sign up for a Tuesday afternoon session (1pm-3pm) or a Wednesday morning (9am-11am) time. This will cover how to use the machine, in addition to data export and analysis.

Starting 12/11/14: Nikon BioStation Demo

The BBIC will host a demonstration of the Nikon BioStation CT,

Who should attend?

  • Anyone interested in kinetic imaging of cultured cells, especially long-term experiments
  • Anyone interested in high through-put screening
  • Anyone working with stem cells
  • Anyone who would like to try out novel uses for this instrument (such as kinetic imaging of fish or fly or frog embryos)
  • Anyone with any other interest/ questions

SCHEDULE OF EVENTS

12/11/14, 10 am-12pm, SR2 301: Presentation and Q&A session about the BioStation, by Ned Jastromb.

12/11/14 1pm- Ned will visit the labs of all interested researchers, to discuss experimental design/sample prep

12/15-17 BioStation setup/ calibration

12/15/14 (afternoon) - 1/16/15 (could possibly be extended to 1/23/15, depending on user interest) BioStation available for experiments. There will be a sign up column on Quartzy, under the “Biology Imaging Core” Equipment signup page. People who are officially signed up have the rights to set the conditions (temp, [CO2], etc.) and use up to 30 available vessel slots. Other interested people may concurrently use any unclaimed vessel slots with permission of the Core Manager. The plan is to run the cell culture experiments first, then try the embryo scans towards the end of the demo.
