Controlling O2 in Physiological Experiments with Cell and Tissue Models

Do you know the real oxygen concentrations near, or even inside, your cultured cells? Are you interested in establishing techniques for monitoring cellular O2 levels?

Then, join our free online webinar to learn more about contactless and quantitative O2 measurement near and in living cells and tissue samples.

Webinar Outline:

A variety of different cell and tissue models are currently being used by researchers to investigate, for example, cancer development, tissue repair, and metabolic responses. However, many of these models have inadequate control of oxygenation conditions and physiological relevance. Optical O2 sensing technology, based on phosphorescence quenching, allows for the precise monitoring of O2. A quantitative measurement of the O2 concentration can be conducted in the gas or liquid phase, macroscopically or microscopically, using point measurements or high-resolution imaging in a non-invasive and flexible manner. This webinar will discuss the weaknesses of common hypoxia workstations, and then describe the available O2 sensing and imaging systems that can and should be integrated in experimental procedures for reliable in-situ control of O2, particularly at the cellular level.
