Meridian Bioscience Air-Dryable LAMP Mixes

Meridian Bioscience has launched its Air-Dryable LAMP Mix and Air-Dryable RT-LAMP 1-Step Mix. The molecular master mixes are designed for fast isothermal amplification of nucleic acid sequences to facilitate the development of point-of-care ambient temperature-stable tests, and to accelerate diagnosis. The mixes cut the usual sample-to-result time of loop-mediated isothermal amplification tests in half, the company said. Both mixes allow more sample to be added and have pre-optimized buffer systems, including enzymes, stabilizers, enhancers, and nucleotides.
