Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu292 of human MX1 protein.

Background

MX1 (Myxovirus resistance protein 1/MxA) is an interferon-inducible antiviral protein that confers resistance to RNA viruses (1-4). MX1 has GTPase activity, and GTP-bound MX1 adopts a conformation that enables interaction with viral nucleocapsids (5-7). This interaction blocks transport of viral nucleocapsids to the nucleus, which prevents transcription of the viral genome (7,8). Structural studies suggest that the antiviral activity of MX1 involves the formation of MX1 oligomeric rings around viral nucleocapsids (9-12).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
