Madison, Wis.-based Novagen now sells KOD HiFi DNA polymerase (manufactured by Toyobo of Japan), a proofreading enzyme for high-fidelity PCR amplification. KOD HiFi DNA polymerase is a recombinant version of Thermococcus kodakaraensis KOD1 DNA polymerase. According to company literature, the enzyme possesses higher accuracy than any other commercially available DNA polymerase, is five times faster than Pfu DNA polymerase, and twice as fast as Taq DNA polymerase. Novagen also sells KOD Hot Start

Most reagents used for reducing disulfide bonds in peptides and proteins have unpleasant odors. To combat this problem, Pierce Chemical Co. of Rockford, Ill., has covalently attached the odorless reducing agent TCEP to an agarose support. Pierce's Immobilized TCEP Disulfide Reducing Gel allows reductions to be performed on the bench-top without the need for a fume hood and avoids the need for dialysis or gel filtration to remove the reducing reagent.

Bio-Nobile Oy of Turku, Finland, has introduced the PickPen™, a novel magnetic particle transfer device. Unlike traditional magnetic separation methods, which generally require aspiration of liquids after separation of bound materials via a magnetic stand, the PickPen removes the particles of interest themselves. First a retractable magnet is inserted into the disposable tip of the PickPen device. The tip is dipped into the sample and removed after the magnetic particles bind. Particles ar

Pierce Chemical Co. of Rockford, Ill., has introduced the UnBlot™ Chemiluminescent In-Gel Detection Kits for detection and visualization of specific proteins. Unlike Western blotting, the technology permits detection of protein directly in the gel, eliminating transfer and blocking steps. The UnBlot kits reduce post-electrophoresis detection time to as little as four hours. Additionally, the technology is compatible with stripping and reprobing protocols, allowing users to reprobe and reop

Berthold Detection Systems of Pforzheim, Germany, has introduced the Luminescence TestPlate for the testing and validation of microplate luminometers.

The Luminescence TestPlate is supplied with a rechargeable battery and evaluation software. Berthold Detection Systems' products are distributed in the United States by Zyl

Madison, Wis.-based Novagen's ColiRoller™ plating beads replace the "hockey stick" method of bacterial plating. Bacteria are commonly spread on agar plates with a bent glass rod that must be immersed in ethanol and placed briefly in an open flame before use; this method can result in uneven spreading and is tedious when preparing multiple plates. ColiRoller beads are a more efficient alternative--simply pipette cells onto a plate, add 10-20 beads, and tilt the plate back and forth to sprea
