Streamline biotech research offering new tools to measure S-Adenosylmethionine (SAM) and Methylation Index. Arthus Biosystems is the first in the world to generate high quality antibodies against S-adenosylmethionine (SAM, AdeMet, SAMe) and S-adenosylhomocysteine (SAH) that allows immunoassays to be used in the SAM, SAH and homocysteine (HCy) related research. Its goal is to bridge the gap between important and useful research data and the potential applications in clinical diagnostic/treatment practices to benefit the public.
