PI3K signaling pathway inhibition limits Arginase 1 activity of M2 polarized macrophages
During their polarization, M2 macrophages were treated with increasing concentrations of LY294002, a reference PI3K inhibitor. ELISA-based quantification of L-Arginine increase in the supernatants (using IS-I-0400 kit) highlighted a dose-dependent inhibition of Arginine catabolism.
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.
