ClonTech Laboratories will be launching its ProteoTuner system on Feb. 20. The system regulates the amount of protein of interest present in a cell “quickly and directly,” the company said in a statement. It enables direct manipulation of the in vivo level of a protein, and because it has very low toxicity, is suitable for animal studies.
Tovatech this week launched the FlowCal 5000 flow meter for calibration of HPLC systems. The device is miniaturized to one-third the size and weight of other models and measures flows to 1 microliter/minute with guaranteed linearity from 0.05 ml/min to 25 ml/min. Flow rate is measured by volume and is independent of the liquid type up to a viscosity of 10 centipoise.
AnaSpec last week launched 25 new catalog peptides. They include Melittin, honey bee: [Ala28]-beta-Amyloid (1-40); and mycobacterium tuberculosis protein Ag85A.
Qiagen this week introduced TissueLyser II, a bead mill that rapidly disrupts up to 48 samples, in 2 by 24 tubes, or 192 samples, in 2 by 96 tubes, simultaneously. In a statement, the company said a variety of samples can be disrupted to release “high quality DNA, RNA, and protein for subsequent purification and analysis.”
