Product Overview
This rabbit polyclonal antibody targets caveolin-2 (gene CAV2) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 18.3 kDa, and the supplier reports an observed band at about 21 kDa.
Caveolin-2 (CAV2) is a caveolar membrane protein that forms hetero-oligomers with caveolin-1 and depends on it for proper localization. It contributes to caveolae formation and has been linked to regulation of signaling, including through its phosphorylated forms. It is often studied alongside caveolin-1 in adipocytes, endothelium and lung.

Immunogen
Recombinant human Caveolin-2 fragment (Met1–Asp162), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 90% and 89%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places caveolin-2 in the nucleus, cytoplasm, Golgi apparatus membrane and cell membrane. Tissue expression noted by UniProt (human): Expressed in endothelial cells, smooth muscle cells, skeletal myoblasts and fibroblasts. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
