LGC, Biosearch Technologies RapiDxFire Thermostable RT

LGC, Biosearch Technologies has launched RapidDxFire Thermostable RT, a thermostable reverse transcriptase designed specifically for diagnostic kit developers. The enzyme's optimum temperature of 55° C to 80° C improves reaction specificity and allows synthesis from diverse RNA templates. It also has a reaction time of five minutes or less, and is recommended for targets under 1 kb. Its extended stability at room temperature make it compatible with automation, and the enzyme is available in a lyophilization-ready Triton X-100-free format, the company said.
