LSAT offers a lyophilized mixture of Avian Myeloblastosis Virus Reverse Transcriptase, RNase H and T7 RNA polymerase called LEM in 5 or 10 reaction kits. It is designed for easy and efficient NASBA reactions where the major product is anti-sense, single stranded RNA. Due to being lyophilized with a Trehalose solution this mixture has strong thermostability even at room temperature.

Trehalose is a remarkable stabilizer that is proven for many molecular biology applications, including NASBA and PCR amplification. LSAT provides Trehalose Dihydrate as a Molecular Biology Grade powder, or a 1M aqueous solution effective as buffer component for proteins, enzymes and cell membranes. We insure there is no detectable RNase and Dnase activity, and that endotoxin concentration meets U.S.P. requirements.
