CELLOMET is a transfer technology platform linked to the MRGM academic laboratory and offering research services in the field of cell metabolism, with a particular emphasis on energy metabolism. Typically CELLOMET will work for academic laboratories to decipher the peculiarities of cancer cells energy metabolism and for pharmaceutical companies to decipher the mode of action of anti-cancer drugs with specific action on energy metabolism.
The strength of CELLOMET, in addition to specific tools for metabolic evaluation, is our recognized expertise in the field of energy metabolism and our capacity to solve related questions both in the clinical or the drug discovery settings
