Clone 56-Caveolin
Isotype IgG1
Cross-Reactivity Mouse (Murine), Rat (Rattus)
Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Please refer to us for technical protocols.
Purification The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name Caveolin
Background Caveolin (VIP21) localizes to non-clathrin membrane invaginations (caveolae) on the inner surface of the plasma membrane. In addition, it is present in the trans-Golgi network (TGN) and in apically and basolaterally destined transport vesicles. Caveolin is a transmembrane adaptor molecule that recognizes GPI-linked proteins and interacts with downstream cytoplasmic signaling molecules, such as src-family tyrosine kinases and hetero-trimeric G proteins. Caveolin forms large lipid-binding oligomers, which are thought to play a role in caveolae formation. It may also function as a scaffolding protein, which organizes signaling molecules. This functional role is supported by the fact that caveolin interacts directly with inactive ras and G-protein alpha subunits. Phosphorylation of caveolin at Tyr-14, Ser-88, and other residues in v-src transformed cells leads to flattening, aggregation, and fusion of caveolae and caveolae-derived vesicles. Thus, caveolin is the principle protein of caveolae and may be involved in v-src mediated cellular transformation.
This antibody has also been reported to cross-react to paxillin in mouse embryonic fibroblasts (MEF), observable to migrate at ~ 68 kDa .
Molecular Weight 21-24 kDa
