AKTAexplorer is a single-unit, high-performance liquid chromatography (HPLC) system designed to quickly develop and optimize purification methods for proteins, pep-tides, nucleic acids, and oligonucleotides. The unit resolves all major purification F. f. i4 "seo tasks, features preset running parameters for about 80 prepacked columns, and prepares buffers automatically from stock solutions. AKTAexplorer supports all method development strategies and all chromato-graphic techniques including ion exchange, hydrophobic interaction, reversed phase, affinity , and gel filtration. Built-in methods for a wide range of columns enable fast media screening, method scouting, and scaling experiments. The instrument is controlled and automated by UNICORN 2.10 software, the most recent of this widely used program, which includes the ability to network with other Pharmacia systems.

Literature Spectrum 2000 FT-IR Spectrometer is a brochure on a modular system that is the next step in Fourier transform infrared (FT-IR) spectroscopy performance and usability. Advances include new optical and sampling features ; control enhancements; and faster ways to generate, display, and interpret spectra. Membrane Filtration Catalog presents products for microseparation and includes an applications guide. Micropure-EZ enzyme removers are featured for rapid enzyme removal of restriction and other enzymes from reaction mixtures containing double-stranded DNA. A high recovery centrifugal ultrafil-tration device recovers proteins from dilute solutions of up to 15 ml. Particle separators and the Gel Nebulizer can be used to extract and concentrate DNA <1 kb from gels. Amicon. Circle 147.
