Manufactured by Biometra (Germany), the Rotaphor utilizes patented Rotating Field Electrophoresis (ROFE) technology to allow separation beyond the limit of conventional horizontal agarose gel electrophoresis. With this method, an electric field between two primary sets of electrodes is stabilized by two sets of secondary electrodes. The electrodes are positioned within a rotor that is rotated above a stationary gel. This format gives users enormous flexibility by choosing vector angles between

Date: November 24, 1997 Chart To most people, a luminometer is something that probably measures "luminos," while a fluorometer measures "fluoros," As simple as that sounds, these analyzers have been occupying valuable bench space in laboratories for decades. Though maybe not considered new and hot techniques in the biotechnology arena, luminometry and fluorometry continue to provide scientists with reliable answers to molecular questions. LabConsumer set out to explore options available to sc

Date: November 10, 1997 Chart 1 Chart 2 It was a busy evening at The Eagle. Less than half a century ago, inside this small Cambridge pub, two gentlemen raised their glasses to salute their remarkable genetic findings. At the time, the two men (and a few close colleagues) were the only souls on the planet privy to the molecular structure of DNA. Does it seem odd, then, that researchers around the globe could be toasting the description of the entire human genome less than ten years from now? Y

Chart 1 Chart 2 Chart 3 Chart 4 Chart 5 Within the last few years, research into signal transduction compounds and pathways has exploded, leading to a growing number of companies that sell antibodies for signal transduction. Whereas in the past, laboratories had to produce their own antibodies-or gain access to them through a network of contacts-dozens of companies now have commercially available signal transduction antibodies. This vast supply of antibodies has made it possible for researche

Date: October 13, 1997 Comparison Chart 1 , Comparison Chart2 You could be home right now. Instead, you are forced to stay at the lab to monitor that 2-D gel you're running. Think of all the things you could be doing instead. Sure, you can fill the time by doing busy work, tidying up the lab or making sense of what you scrawled in your notebook hours ago. If you run multiple gels, multiple protocols, or like the convenience of programmability, programmable power supplies were designed to meet

Date: September 29, 1997 Product Comparison Table Most researchers have probably been coerced into listening to their superiors and mentors reveal at length what thermal cyclers used to be. The twelve years since the description and publication of the polymerase chain reaction (PCR) have given scientists and manufacturers ample time to create and refine highly specialized machines dedicated to thermal cycling. The thermal cyclers of today have expanded applications and increased performance a

Date: September 1, 1997 Comparison Chart Laboratories pressed with weighing needs can choose from several classes of balances comprised of virtually hundreds of models with unique designs, functions, and capacities. Balances have been redesigned and upgraded from year to year, and the list of available features and options keeps growing. What exactly makes an analytical balance an analytical balance? For the purposes of this profile, we will define an analytical balance as an instrument capa

What better way to create the ideal in vivo environment, in vitro, than via CO2 incubation? In 1885, Wilhelm Roux kept the medullary plate of a chicken embryo alive for several days in saline solution. Since CO2 incubators became commercially available in the late 1960s, manufacturers have been given the opportunity to improve their incubators and introduce cell culturing to the age of high-tech biotechnology. With numerous options available for most CO2 incubators, it is important to determine

LabConsumer recently invited a local representative of the Rainin Instrument Company to our office, giving our staff the opportunity to test drive Rainin's unique ShaftGard 10 ml FinePoint pipette tips. These tips allow for full immersion into 0.5 to 2.0 ml microcentrifuge and PCR tubes and are manufactured with several features designed to reduce the likelihood of cross-contamination and ensure repeatability. ShaftGard tips are compatible with Pipetman P-2 and P-10 pipettes, as well as Rainin
