Abstract: The methods and compositions provided herein relate to the discovery of 13 STR are markers found on the human Y chromosome with surprisingly high mutation rates when compared with 173 other Y-STR markers known today, including those that are in common use in forensics. In addition to theoretical expectations based on elevated mutation rates, these 13 rapidly-mutating (RM) Y-STRs proved to be suitable for differentiating between closely related males, as well as between more distant male relatives and much more so than the most-commonly used Y-STRs in forensics. Our new set of RM-Y-STRs is expected to overcome the current dilemma of Y-chromosome analysis in forensic applications from current male lineage identification towards male individual identification in many cases, due to their extraordinary mutation properties as discovered here.

Abstract: Methods and apparatus are presented that facilitate electrophoresis of prior-cast, hydratable separation media, usefully immobilized pH gradient (IPG) strips. The method exploits the swelling of prior-cast, hydratable separation media upon rehydration to help lodge the media in an enclosing member that permits spaced electrical communication with the enclosed separation media. The electrical communication permits a voltage gradient to be established in the enclosed separation medium sufficient to effect separation of analytes therein. Cassettes, buffer cores, electrophoresis systems and kits are presented for effecting the methods of the invention.

Abstract: The mechanism of the UV light-induced reaction between the indole moiety of tryptophan and chloroform, and the structure of the modified tryptophan and polypeptides including such modified tryptophan residues. The excited indole moiety, which is formed upon UV light irradiation, emits a solvated electron which initiates a series of events that yield fluorescent derivatives that have CHO group covalently bound to the indole moiety. These derivatives are herein referred to as formyltryptophan, and are relatively stable. Similar reactions are observed when 5-hydroxytryptophan, 5-fluorotryptophan, or N-methylindolacetate are used in place of tryptophan, or when other haloalkanes, such as trichloracetic acid, trichlorethanol, trichlorethane, bromoform, and iodoactetate are used in place of chloroform. The derivatives can be used in a variety of applications in fluorescence spectroscopy, and for nuclear magnetic resonance, X-ray crystallography, infra-red spectroscopy, circular dicroism and mass spectroscopy.
