Background Information
Mitochondrial antiviral-signaling protein (MAVS) is also known as virus-induced-signaling adapter (VISA) or IFN-β promoter stimulator protein 1 (IPS-1), it is widely involved and required for innate immune defense against viruses. MAVS, present in T cells, monocytes, epithelial cells and hepatocytes, contains CARD and transmembrane domains which are essential for antiviral functions. MAVS is able to interact with various cellular proteins including DDX58/RIG-I, IFIH1/MDA5, TRAF2, TRAF6, TMEM173/MITA, IFIT3 and etc. It can undergoe phosphorylation on multiple sites and ubiquitination, which may together cause the molecular weight migrate to about 70 kDa despite the predicated 57 kDa.

Reviews
What customers say
The single review (2/5 stars) reports a Western Blot on HeLa cells at 1:2000 dilution. The user was not convinced by the anti-MAVS antibody, as they expected two bands—short MAVS (~55 kDa) and full-length MAVS (~72 kDa)—but consistently observed only a protein smear and a single 72 kDa band, with the expected 55 kDa band never appearing. The reviewer noted their lysates were intact, since other target proteins in the same samples revealed clearly, suggesting the issue was antibody-specific rather than sample degradation.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Damien (Verified Customer) (09-03-2019) | No convince by this anti-MAVS antibody.In fact, in human cells MAVS protein is expressed in two differents forms : short-MAVS (55kDa) and full-length MAVS (72 kDa). So I have to observe two bands by WB. However, after using different conditions with this antibody according to the manufacturer's protocol I always observe a smear of protein, and one band at 72 kDa. The expected on around 55 kDa never appear. Note that my cells lysates were not degraded since the others proteins that I want to reveal were great.
