We have the problem of our cells differentiating well on specific coverslips,
and not those of mattek dishes. In the meantime of trying to identify other dishes, we continue to use coverslips. We image just with a dipping lens, but would like some more resolution. Is it possible to mount the "coverslip with cells" upsidedown onto a new mattek dish and then image it using an inverted microscope with a water immersion lens? Is there another way around this? Regards |

Hi Waldo,
we use custom made coverslip holder built in our toolshop. This works very well for us. Cells grow on coverslips and whenever needed single coverslips with cells are collected from the cell culture. The coverslip holder is simple a metal device with an adapter for coverslips in the middle. Imagine the metal device as a metal object slide with a hole in the middle, designed in a way, that the coverslip exactly fits into it, without passing through. E.g. for a 18x18 coverslip the hole has dimensions of ~16x16. Another piece of metal with a ~16 circular whole in it and a rubber seal is placed on top. Immidiately after transfer of the coverslips new buffer is added. The rubber seal of the upper device assures that everything is leak-proof. Maybe after this procedure some recovery time for the cells is appropriate. Cells can then be imaged even with an oil immersion objective - if refractive index mismatch is no problem...

Hi Waldo,
I think what Roman describes is also sold by a company in Switzerland. They are called Life Imaging Services: http://www.lis.ch/ No commercial interest, just a satisfied customer.

Hi Waldo,
Your other choice is to get a Sykes-Moore chanmber made by Belco. The are a simple chamber with a rubber seal and a screw on top that holds it all together. We use them daily and they work great. You can grow your cells on the coverslips then just mount them in the chamber and image happily. The only problem i have had with them is that you cannot usually image to whole coverslip. When mounted the cover slip is recessed a little bit which means large objectives can only focus on the middle area of the cover slip. A big thanks to Steve Cody for buying these in for the Centre. Also I have no comercial intrsts with Belco. Cheers Cam Cameron J.

Hi Waldo,
I know others have already replied with some suggestions but I have one more for you to consider. I recently bought two chambers from Quorum Technologies, called Chamlide chambers. They are designed to take various sizes of coverslip ( I bought the 25mm one) and are magnetic. I have only just bought them having seen them at the Vancouver LiveCell course and haven't yet tried them but they seem like they will work really well. No commercial interest!

Dear friends,
in my department at the Italian Institute of Technology there are 20 PhD positions open. A specific one is reported here. The complete call can be found at www.iit.it. All the best Alby ----- Diaspro Lab call ---- Theme 3.1: Optical Nanoscopy and advanced high-resolution microscopy. Tutor: Alberto Diaspro A recognized advantage of optical microscopy lies in the fact that allows non-invasive three-dimensional (3D) imaging of live cells at the submicron scale with high specificity. The advent of the visible fluorescent proteins and of a myriad of fluorescent tags pushed fluorescence microscopy to become the most popular imaging tool in cell biology. The confocal and multiphoton versions of fluorescence microscopy reinforce this condition. However, like any other standard imaging system relying on focused light, all these microscopes are limited in spatial resolution because the smallest possible spot size is imposed by diffraction. Several approaches aimed at overcoming the diffraction limit. Stimulated Emission Depletion (STED) microscopy is one of the most promising Optical Nanoscopy approaches allowing an ultimate resolution of 7.6 nm in the optical regime. In STED microscopy, fluorescence emanating from the periphery of the focused excitation beam is suppressed by a second properly shaped beam that depletes the excited state population through stimulated emission. This effectively narrows fluorescent molecule signature, the point spread function (PSF) of the microscope, to permit superresolved images to be acquired. The Optical Nanoscopy theme is related to the development of an original STED architecture based in white light laser illumination and to its characterization for key applications to tracking of molecular events in living cells towards the study of degenerative processes like neuro-diseases, tumor progression and nanoparticle toxic effects on biological systems. Variations on the theme will include Fluorescence Photo- Activation Light Microscopy (FPALM) and Single Plane Illumination Microscopy (SPIM) approaches.

I'd also recommend the trying the plastic cover-slip thickness membrane
slides and wells from Ibidi: Ibidi μ-well MultiWell, micro-channel and Flask 3x1" slides [new product] for slide cell culture and hi-res microscopy imaging. Go to Ibidis web site. Wells and channels with a 150μm membrane cover-slip on a standard slide http://www.ibidi.de/products/p_disposables.html Griener also make utra-thin Lumox membrane [as well as glass or plastic] wells and slides for inverted microscope viewing: Greiner bio-one MultiWell and SlideFlask slides [new product] for slide cell culture and microscopy imaging. Download Greiner Culture Slide Brochure. 1 to 8 wells on a Lumox membrane, cover-slip or glass slide http://www.well.ox.ac.uk/cytogenetics/downloads/Griener MultiWell & Flask Slides.pdf You can of course buy the Mattek dishes as uncoated, poly-d-lysine coated, or collagen coated, plus they offer two cover-slip surfaces [standard glass and plastic CS1 - the latter's unsuitable for oil immersion though] that might help. http://www.glass-bottom-dishes.com/faq.html#typedish http://www.glass-bottom-dishes.com/coverslips.html Our workshop back at the Institute of Ophthalmology, UCL, did try making our own 'Mattek' style dishes with coverslips of our choice, but it was hard cutting out the circle at the base of the Petri dish and they gave up. I did consider laser cutting out-sourcing to make the hole [that we used very successfully for cutting our plastic CR-39 autoradiography 3x1" slides years ago] and applying the cover-slip of choice, but it was easier just buying in the Mattek dishes as they generally worked OK for our cell biologists. Most suppliers offer free samples to try out.

maybe use a couple of coverslip as spacer, so the cells won't be under pressure.
good luck.

Hi Waldo,
One more suggestion. We have been selling the AttoFluor chamber (A7816) for over a decade for this application as well. Your coverslip (25mm round) and our holder. Very simple, autoclavable design.
