Arginine quantification in human plasma samples
ARG was quantified in human plasma samples from 19 healthy donors and 46 cancer patients from several histotypes using IS-I-0400 Arginine ELISA kit. As depicted, ARG level was lower in cancer patients than in healthy subjects thus arguing for an exagerated Arginase activity in cancer patients.**** p<0.0001
Arginine ELISA kitRef: IS-I-0400
Arginine (ARG) is a basic non-essential amino acid well known to participate in physiological functions such as i) vascular tone homeostasis as contributing to the production of nitric oxide (NO) and ii) immune response control, through NO synthase (NOS) and Arginase enzymes, respectively.
The Arginine (Arg) ELISA kit allows for the determination of Arg in serum and plasma samples working with a sample volume of 20μL. The kit is easy to implement and well suited for both preclinical and clinical studies.
