Look at something with a known size, e.g., a fluorescent slide with known grid spacing. On Wed, Nov 30, 2016 at 2:01 PM, Tim <[hidden email]> wrote: ***** |

Would such a slide be commercially available? I did not see any slides with fluorescent grids after doing a search. |

For a grid - just stick a hemacytometer on the microscope. If you want to get fancy, put a (dilute) solution of fluorescein or a dilute solution (to not waste money) of fluorescent antibody on it. You can focus in brightfield. enjoy, George On 11/30/2016 2:51 PM, Tim wrote: > ***** > To join, leave or search the confocal microscopy listserv, go to: > http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy > Post images on http://www.imgur.com and include the link in your posting. > ***** > > Thanks Gary.

There are some commercial fluorescent targets with known grid patterns, for example, http://www.maxlevy.com/category/fluorescent-tragets.html Please make sure you select one that suits for your purpose. On Wed, Nov 30, 2016 at 3:51 PM, Tim <[hidden email]> wrote: ***** |

Hi Tim, If you are happy with precision of a few percent, you could use
Powerpoint or similar software, and a decent printer, to print out your own crude sample on regular paper, and image it in transmitted or reflected light.
The spacing on my sample goes down to 500 microns, but your printer might do much better. Cheers, Jeff From: Gary

You can also paint the printed grid with a fluorescent marker, to make it a crude fluorescent target. On Wed, Nov 30, 2016 at 5:52 PM, Reece, Jeff (NIH/NIDDK) [E] <[hidden email]> wrote: ***** To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/ |

If you have a spare etched micrometer slide, you could "paint" the etched lines with the fluorescent marker. We have a very old, etched line slide that someone probably modified to be fluorescent at some time. Swipe the marker (or make a dye paint) over the etched area, let it dry, then carefully wipe the surface clean & at least some of the fluor should stay in the etched lines.

We use the following grid micrometer with a layer of fluorescein and a coverslip: http://www.edmundoptics.com/test-targets/image-analysis-test-targets/multi-grid-standard-stage-micrometer/58607/ The fluorescence reflects off of the mirrored grid nicely, and allows for the width and height to be measured simultaneously. It is also really helpful for aligning a brightfield system to an MP scan field, including any transformations.

It gives a beautiful bright-field image, and fluoresces intensely right across most of our Mai Tai wavelengths. So you can use it to align BF and 2P captures and transformations, as previously mentioned. But we also find it very useful as a startup check for our 2P system to check detectors, beam alignment etc. We got ours with the Zeiss, but I believe you can buy these slides quite cheaply e.g. http://www.msmedia.com.au/convallaria-rhizome-training-slide-stained-for-fluorescence.php Bill Bennett |
