ThermalSeal RT2RR

Polyester sealing film

Excel Scientific, Wrightwood, Calif, has developed a new 50-µm polyester sealing film designed for real-time PCR. ThermalSeal RT2RR is sized to fit within the edges of raised-rim, 96-well plates. It has the consistent ultrahigh optical clarity of Excel’s ThermalSeal RT films for more reproducible, reliable, and consistent DNA amplification measurements. An inert, strong, temperature-resistant adhesive ensures reliable sealing around each well, and two end tabs assist in positioning the film. Easy removal of the end tabs at perforated boundaries prevents lifting and higher evaporation rates that can occur with films that overlap the plate rim. The film is recommended for specific DNA sequence detection in clinical diagnostics, forensic science, and basic research.

TIRF Illuminator

Compatible with a variety of lasers

Olympus, Center Valley, Pa, has introduced its latest innovation for objective-based total internal reflectance fluorescence (TIRF)—a new multicolor, multi-angle illuminator that allows simultaneous multichannel laser TIRF illumination. The TIRF illuminator allows up to three discrete laser lines to be used simultaneously for illumination, each with its own critical angle. In TIRF, the light’s angle of incidence dictates how deeply the evanescent wave penetrates into tissue, and lasers of different wavelengths require varying angles to operate at their peak. In comparison with other TIRF systems—where laser light of various wavelengths passes through a single fiber, necessitating switching lasers and adjusting the critical angle to achieve maximum performance—the Olympus illuminator employs three separate fibers to maximize results. It is also easier to operate, since the lasers are adjusted once, at the beginning of the experiment, and do not need to be adjusted again. The TIRF illuminator is compatible with a wide variety of common gas and diode lasers, including the widely used 405nm diode laser.
