    Abstract: A viscous electrophoresis separation medium is disclosed. The medium is formed by a matrix formed by a copolymer composed of hydrophilic polymer segments having selected, substantially uniform segment lengths, and a plurality of hydrophobic polymer segments carried on, and spaced from one another by the hydrophilic polymer segments. Also disclosed is an electrophoresis method which employs the separation medium, and novel copolymers used in forming the medium.

    Abstract: A time-of-flight mass spectrometer (11-13) in which sample ions are generated from a target (23) and are focussed into an ion beam (14) that is incident onto a detector (13). A barrier (212) that defines an aperture (213) in the path of the ion beam is positioned to block ions having an extra large deviation from an average time-of-flight of the ions, thereby improving resolution. The aperture can be adjusted to adjust a tradeoff between sensitivity and resolution. Alternatively, the position of the aperture or the bias on an einzel lens can be adjusted to control this resolution.

    Abstract: A method for synthesizing sulfurized oligonucleotide analogs, such as phosphorothioate and phosphorodithioate analogs, is provided that employs a thiuram disulfide as a sulfurizing agent. The method of the invention may be used to sulfurize any phosphorous(III)-containing intermediate. Preferably, the method is practiced on a commercial DNA synthesizer using phosphoramidite and/or phosphorthioamidite intermediates.

    Abstract: An automated apparatus (11) is programmed to perform a process by arranging a sequence of first icons (69) on a display (15) in the order of the process, wherein the first icons (69) represent functions of the apparatus (11), and wherein at least one of the first icons (69) provides a visual representation of a function of the apparatus (11). Said at least one of the first icons can be expanded to show second icons (81) that comprise the function of said at least one of the first icons (69), and at least one of the second icons (81) provides a visual representation of a subfunction of the apparatus (11). In a preferred mode, when said at least one of the first icons (69) is expanded, said at least one of the first icons (69) maintains its same sequential relationship on the display (15) to the other of the first icons (69) in the sequence as before it was expanded.
