Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

Flotillin-1 Antibody detects endogenous levels of total flotillin-1 protein.


Species Reactivity: Human, Mouse, Rat, Monkey

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding residue surrounding Ile368 of human flotillin-1. Antibodies are purified by peptide affinity chromatography.

Flotillins belong to a family of lipid raft-associated integral membrane proteins that carry a evolutionarily conserved domain called the prohibitin homology domain (PHB) (1). Flotillin members are ubiquitously expressed and located to non-caveolar microdomains (lipid rafts) on the cell plasma membrane where they support signal transduction and regulate lipid raft motility and localization (2-5). Two flotillin members have been described, flotillin-1 and flotillin-2. In addition to its colocalization with lipid rafts on the plasma membrane, flotillin-1 also has been found at compartments of the endocytic and autophagosomal pathways, such as recycling/late endosomes, the Golgi complex, as well as the nucleus (6,7). Flotillin-2 is mainly localized to the plasma membrane and is prevalent in cell-cell contact sites. However, overexpressed flotillin-2 has also been found in the late endosome (4,8,9). Both flotillin-1 and flotillin-2 are commonly used as lipid raft associated markers.
