Product Overview
This rabbit polyclonal antibody recognizes paxillin (gene PXN) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 64.5 kDa, and the supplier reports an observed band at about 65 kDa.
Paxillin (PXN) is a focal adhesion adaptor protein that links integrin-based adhesions to the actin cytoskeleton. It is phosphorylated by FAK and Src and serves as a docking site for many signaling and structural proteins, so it is widely used as a marker in studies of cell adhesion and migration.

Immunogen
Synthetic peptide based on the sequence of at the C-terminal of human Paxillin. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places paxillin in the cytoplasm and cell junction. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
