Oxygen Measurement Core

O2M’s "Oxygen Measurement Core" is a contract research facility. It provides full cycle in vitro and small animal in vivo oxygen measurement services.

All experiments are performed using O2M’s preclinical oxygen imager, JIVA-25™, that can accommodate sample size up to 40 mm.
O2M can carry research projects to its full experimental cycle, from sample preparation and cell seeding to in vitro and small animal in vivo oxygen imaging.
O2M can also provide biologic assays and histology assessments, publication quality data/images, and support your submission to peer reviewed journals leading up to publication of the work.
O2M’s clients are academic institutions, research foundations, and industry partners. See our recent publications from Oxygen Measurement Core as an example.
