Courtesy of RobmarCommon sense says that biotechnology is not child's play, but to former surgeon Bruce Bryan, it is. Bryan founded Pinetop, Ariz.-based Prolume to develop a line of glow-in-the-dark toys based on the luciferin/luciferase reaction, the same process behind firefly light and chemiluminescent assays.The idea dates back to Bryan's childhood, when he observed sea creatures lighting up the water during a scuba diving excursion. As an adult he tinkered with bioluminescence and eventuall

Rather than carrying their gel trays to the dark room, they can whip out the diminutive UV Light Pen ($17, US), from Technika, for on-the-spot gel analysis.The light pen uses LED (light-emitting diode) technology. Instead of filaments, LEDs use low-power semiconductor chips. As a result, the Light Pen "virtually uses no electricity, so the batteries last a
Letting the Air Out

Unless bombarded with noxious fumes or blowing dust, we don't usually think about the air we breathe. But biologists working with sensitive samples such as anaerobic bacteria don't have that luxury.Essex, UK-based Optiglass' GL14 series of spectrophotometer cells for anaerobic samples offers a convenient way to prevent exposure of samples to the surrounding environment.The cuvettes are sealed with a septum top through which liquid samples or gas can be injected and removed without the need to op
