Mo Bio Laboratories this week launched Dye Dots dry gel loading dye for gel electrophoresis.

According to the company, Dye Dots are the first gel loading dye available in dry, ready-to-use aliquots that resolubilize in seconds, eliminating the need to use parafilm to prepare sample aliquots for gel loading.

The dots are composed of a patent-pending formulation that enables rapid reconstitution upon application of a DNA or RNA sample, and immediate loading into non-denaturing TAE and TBE agarose gels. The Dry Dots are arranged in a low-profile plate containing 72 aliquots, and are compatible with all types of DNA and RNA samples, the company said.

Labnet, a division of Corning Life Sciences, has introduced its AccuSeal semi-automated microplate sealer, designed for consistent heat sealing of microplates.

AccuSeal works with a wide range of microplates, including PCR, assay, and deep-well storage plates. It also accepts shallow plates and high-profile plates, and can be used with most manufacturers' heat sealing films, Labnet said.

Sealing temperature and time and adjustable, and can be precisely set using the instrument's digital control panel. The use places a microplate on the open drawer with a sealing film on top and presses the "seal" button, and the process is carried out automatically.
