Krista Rantanen, Ph.D., Director of Scientific, Applications, Baker Ruskinn Oxygen is a fundamental factor for most life forms. For life science researchers, O2 is an electron acceptor, a highly reactive molecule that is essential for life and a molecule that affects every single event and reaction in biology. Ambient oxygen is most often considered to be 21% or 160 mmHg. This number is close to truth at sea level. However, hardly any research focuses on studying objects in ambient air; instead, researchers use cells, tissues or other material that, in order to be representative to real biological events, needs to be grown in dedicated culture stations with controlled O2 conditions.
