18, 2017 /PRNewswire/ — Tetracore today announced that the T-COR 8 portable real-time PCR thermocycler has achieved CE-IVD status under the European Directive on In Vitro Diagnostic Medical Devices.

The thermal cycling conditions were as follows: 95°C for 3 min, 98°C for 20 s, 58°C for 20 s, and 72°C for 10 min, with only one cycle. dsDNAs were purified from the PCR product using 0.85 volumes of ...

The water cycle is an amazing process that we started to talk about when discussing evaporation a couple of weeks ago. In this simple science activity, children make a model of the water cycle to show ...
