[quote="Yury_P"]I think the item you are looking for is still manufactured by Richard-Allen Scientific. They call it Cytoseal. This xylene-based mounting medium is made of high-quality synthetic resins and contains an antioxidant to inhibit stain fading and yellowing of specimen. Rapid drying medium allows specimen examination soon after application. It will soon become a supplied product from [url=http://www.microscopes.com/supplies-accessories.html]Microscopes.com[/url].[/quote]

The solvent in this seems to be toluene <br />rather than xylene, but it would probably solve my problem, if I could get it in the UK. <br />Only Cole-Parmer seem to supply it here (in cases costing about $120 each), and I can't buy it from them because the wretched computer ordering system just installed in my lab, allows me to order only from Fisher Scientific.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="templates/op/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> <tr> <td width="22%" align="left" valign="top" class="row2"><span class="name"><a name=""></a><b>Yury_P</b></span></td> <td class="row2" height="28" valign="top"><table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td width="100%"><img src="templates/op/images/icon_minipost.gif" width="12" height="9" alt="Post" title="Post" border="0" /><span class="postdetails">Posted: Tue Jun 19, 2007 11:40 pm<span class="gen"> </span> Post subject: </span></td> </tr> <tr> <td colspan="2"><hr /></td> </tr> <tr> <td colspan="2"><span class="postbody">I think the item you are looking for is still manufactured by Richard-Allen Scientific.

It has a very high refractive index, so renders tissues transparent. Useful dyes, including safranin and eosin are not soluble in it. Most important of all, unlike Canada Balsam, it is non-fluorescent. I understand that it consists of a mixture of methacrylate polymers in xylene and shrinks a great deal during setting. <br /> <br /> With the takeover of BDH by Merck and subsequent sale of the BDH range of products to VWR, all trace of this product seems to have been lost. <br />Does anyone know where to get it? Can you make it by dissolving Perspex <br />(Lucite) in xylene? I am familiar with Cargille Meltmounts: they are no substitute because they tend to fluoresce strongly. Also DPX deteriorates on aging. In preparing test slides for confocal microscopy I am seriously hampered by the lack of this material.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="templates/op/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
