http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Hi all, Would like to ask anyone who has used LabTek II's Chambered Coverglass and Chamber Slide. I read from the FAQ on their website, that the Chamber Slide's upper structure is made of polystyrene, which is not compatible with many fixation reagents; and thus, it is designed for upper structure and gasket removal before fixing, staining and coverslipping. However, i found from their comparison chart that the upper structure of their Chambered Coverglass is also made of polystyrene, BUT the upper structure is non-removable. Why is it so? Does this mean that fluorescence staining has to be done elsewhere prior to transfer into the Chambered Coverglass? And are the two products suitable for fluorescence work with inverted microscope? I have the impression that Chambered Coverglass is great for inverted microscope, and Chamber Slide is for upright microscope. Please advise. Thank you! Cheers, Rachael Lim |

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Rachael, the LabTek Chambered Coverglass is designed for work on an inverted 'scope; you work with a solution in the chamber which can keep the cells alive, and you can change the media (carefully!) during the your observations if you want to. The upper structure cannot be removed as this would break the thin glass. The Chamber Slide is built on normal thickness glass, which is strong enough to allow the polystyrene structure to be removed, and then a #1.5 coverslip can be placed over the cells (and a drop of medium) using nail varnish or vacuum grease around the edges to seal it. The slide can then be observed on an upright or inverted 'scope, but the cells will only live for a short time. When you remove the polystyrene structure, it is important to check that all of the silicone gasket material comes away, as a piece of this can prevent the coverslip from sitting down properly, so you may not be able to focus on the cells. You normally stain and fix before removing the plastic structure, but you have to use a fixative that is compatible with these materials.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Yes. The chambered coverglass is great for inverted scopes. I have used the chambered coverglass a lot and have had no problems fixing with 10% buffered formalin, my fixative of choice. You can probably get by with most fixatives if you use a small volume and you shouldn't need to fix cultured cells for very long. The only problems I have had with our set up is that the end chambers are sometimes hard to image with our coverglass stage insert and the plastic tab has to be cut off (a change in manufacturing happened about 2 years ago, not sure why, anyone?). I usually only use the center 4 wells of an 8 chambered coverglass. The chambered slides can also be used on an inverted scope but I don't like the small gap that remains even after removing the gasket and therefore almost always image in the chambered cover glass with a small volume of PBS or HBSS and a water immersion objective for higher magnifications. Good luck. -Lars -----Original Message----- From: Confocal Microscopy List [mailto:[hidden email]] On Behalf Of Rachael Lim Sent: Tuesday, October 30, 2007 10:15 PM To: [hidden email] Subject: LabTek chambered coverglass vs. chamber slide Search the CONFOCAL archive at http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Hi all, Would like to ask anyone who has used LabTek II's Chambered Coverglass and Chamber Slide.
