General description

ARNO (Cytohesin-2) is a guanine-nucleotide exchange factor that belongs to Arf family of GTP-associated proteins. ARNO has been shown to modulate the movement of mouse preadipocyte 3T3-L1 cells. Studies have reported that cytohesin-2 is overexpressed in pulmonary cancers and can also serve as biomarker of prognosis in hepatocellular carcinomas.
Monoclonal Anti-ARNO (Cytohesin-2) reacts specifically with ARNO, and does not cross-react with other members of the cytohesin family. The antibody associates with human and rat ARNO.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Mouse monoclonal anti-ARNO (Cytohesin-2) antibody can be used for western blot (5-10μg/mL using a whole extract of rat brain), microarray, indirect ELISA and immunocytochemistry applications.

To determine if ARNO binds to phosphoinositides, a protein-overlay assay was performed using monoclonal mouse anti-ARNO as the primary antibody for ARNO detection on membranes spotted with phosphoinositides and incubated with ARNO.
