Since it probably predates Wikipedia, it is unlikely that we will ever know who first used this theme.<\/p>\n<p>An aptamer is a molecular tool that is used to find, grab, affect through contact, a particular tiny thing, like another molecule (but even perhaps a whole cell or even a tiny organism).  The process of probing around in the microscopic world for research, engineering proteins or molecular interactions, pharmacology, etc. might use aptamer molecules in a number of different ways.  The trick with using aptamers is to find them either from natural sources (rare) or from a large pool of diverse semi-randomly tossed together molecules.  A method used to put a large number of different candidate molecules to the test in order to identify an aptamer for a particular tiny thing (like a bit of DNA, for instance) is SELEX.<\/p>\n<p>The SELEX method is complex, perhaps even boring, and certainly has the potential of becoming mundane to Maureen McKeague, who has developed a SELEX for targeting homocysteine.  So, let&#8217;s see how Maureen does this in the form of Interpretive Dance!  And since the target molecule is a HOMOcysteine, we hope and expect there will be a homo-erotic aspect to the performance.<br \/>\n<!--more--><\/p>\n<p><iframe loading=\"lazy\" src=\"http:\/\/player.vimeo.com\/video\/14528924\" width=\"400\" height=\"265\" frameborder=\"0\"><\/iframe><\/p>\n<p><a href=\"http:\/\/vimeo.com\/14528924\">Selection of a DNA aptamer for homocysteine using SELEX<\/a> from <a href=\"http:\/\/vimeo.com\/user4543629\">Maureen McKeague<\/a> on <a href=\"http:\/\/vimeo.com\">Vimeo<\/a>.<\/p>\n<p>This is, as I&#8217;m sure you now, part of the Dance your PhD context.
