HDAC Fluorimetric Cellular Activity Assay
13 March, 2007HDACs are typically found in multiprotein complexes and are tightly regulated by subcellular localisation, phosphorylation, and likely by other mechanisms.
Tissue homogenising kit
08 December, 2006Omni Tip Tissue Homogenising Kits are suitable for PCR, DNA and RNA sample preparation. Each kit is supplied with a 7 mm diameter, 95 mm long stainless steel generator probe and 12 disposable probes.
Automated cell separator
13 November, 2006Robosep is claimed to be the first instrument to provide true 'walk-away' automation of magnetic cell separation. Using column-free technology to isolate cells by either positive or negative selection, Robosep can label and separate up to four samples (volume between 2.5 x 107 and 8 x 109 cells) at one time. Robosep is easily controlled by an integrated colour touch screen and provides its users with the convenience of using EasySep Reagents and disposable tips to eliminate cross contamination.
Cell counter plus analyser systems
11 September, 2006The CASY series of electronic cell sizers not only determine cell counts and cell volume but importantly differentiate viable cells from dead cells, cell debris and cell aggregates.
Live cell manipulator
07 July, 2006Laser tweezers are non-contact tools that use light to trap, move and fuse particles, cells or organisms. An infrared laser beam is focused through an objective lens to create an intense optical radiation field. The resulting photon pressure at the surface of the particle or cell enables the operator to move the cells at will, sorting, separating or collecting the cells as required. By combining the system with an ultraviolet laser, cells can be cut free of surrounding structures enabling micro dissection. Where two cells have been trapped by the laser tweezers, the ultraviolet laser can be used to cut the cell membranes allowing the cells to fuse together. A similar process enables operators to insert particles into the cell, for example fluorescent beads, or to perform targeted transfection into the cells of DNA or proteins.
Cell harvesting and blood separation
08 February, 2006Beckman Coulter has introduced an adapter that spins 50 mL conical tubes in the Allegra X-15R and X-12 Series benchtop centrifuges. The adapter accommodates 28 tubes per run in a BioCertified, self-balancing rotor and is suitable for cell harvesting and blood separation applications. The adapter runs at up to 5250 x g in the Aries 4 x 750 mL self-balancing rotor, which detects and automatically corrects for imbalance, continuing the run without shutdown.
Differential cell sorting speeds sample preparation
08 January, 2006Researchers at Sandia National Laboratories in California have developed an enhancement to a dielectrophoresis system that they say could revolutionise the way biological sample preparation is conducted
Automated tissue arrayer
10 October, 2005The Beecher Instruments ATA-27 automated tissue arrayer makes construction of high-density tissue microarrays fast, accurate and reliable. The instrument can accommodate nearly all current tissue cassettes and can be easily adapted to array large or odd-shaped specimens.
Tissue culture dishes
20 June, 2005Nunc has introduced non-treated tissue culture multidishes and EasYFlasks, for research on living cells where attachment is not needed.
Cell culture mapping system
08 February, 2005In a recent project, electrophysiology researchers at Westmead Hospital in Sydney required a system to acquire and analyse signals measured using a micro-electrode array
