Product Details


The ELISA kit CSB-EL002005MO is applied to quantitatively detect the content of the Arginase-1 (ARG1) in samples of serum, plasma, and tissue homogenates. The detection mechanism of this mouse ARG1 ELISA kit is based on the sandwich assay. The standards or samples are added to the microtiter plate wells pre-coated with ARG1 specific antibody. Biotin-labeled ARG1 antibody and HRP-avidin are successively pipped into the wells, forming the immune complex. The solution develops color after the addition of TMB substrate. The content of ARG1 can be quantitatively determined by measuring the optical density of color with a microplate reader. This ELISA kit has been verified with high sensitivity, excellent specificity, a precision of less than 10%, good correlation and linearity, and high recovery.

ARG1 is a cytosolic enzyme constitutively expressed in the liver cells. It is responsible for the hydrolysis of arginine to ornithine and urea and plays a major role in the hepatic urea cycle. The resulting polyamines are important for cell proliferation and clearance of protein degradation-produced toxins. ARG1 deprives nitric oxide (NO) synthase of its substrate and down-regulates NO synthesis. ARG1 deficiencies cause the autosomal disease argininemia that is featured by hyperammonemia. Studies have recently demonstrated that ARG1 is induced in alternatively activated macrophages and is involved in anti-inflammation, tumor immunity, tumor proliferation, metastasis, and immunosuppression-associated diseases. ARG1 may be expressed in the myeloid cells infiltrating tumors and is typically found in the majority of hepatocellular carcinomas.

Target Data

Function Key element of the urea cycle converting L-arginine to urea and L-ornithine, which is further metabolized into metabolites proline and polyamides that drive collagen synthesis and bioenergetic pathways critical for cell proliferation, respectively; the urea cycle takes place primarily in the liver and, to a lesser extent, in the kidneys.
