Product Overview
This rabbit polyclonal antibody targets mitochondrial antiviral-signaling protein (gene MAVS) in human samples and is validated for flow cytometry, IHC, ICC/IF and Western blot. The predicted molecular weight is 56.5 kDa, and the supplier reports an observed band at about 75 kDa.
MAVS is an adaptor protein on the outer mitochondrial membrane that relays signals from the cytosolic RNA sensors RIG-I and MDA5. When these sensors detect viral RNA, MAVS forms large aggregates that activate TBK1 and IKK, leading to IRF3 and NF-κB activation and type I interferon production. It is a central readout in antiviral innate immunity research.

Immunogen
Recombinant human MAVS fragment (Leu34–Gln96), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 72.6% and 69.4%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt places mitochondrial antiviral-signaling protein in the mitochondrion outer membrane, mitochondrion and peroxisome. Tissue expression noted by UniProt (human): Present in T-cells, monocytes, epithelial cells and hepatocytes (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
