Anti-PTK2 (phospho Y397) Antibody

This rabbit polyclonal primary antibody from Antibodies.com targets PTK2 phosphorylated at tyrosine 397. PTK2, also known as focal adhesion kinase, participates in cell adhesion, cytoskeletal organization, migration, and signaling downstream of extracellular cues.

The unconjugated IgG reagent is intended for western blot applications and has reported reactivity with human, mouse, and rat PTK2. Its phospho-specific recognition is useful for comparing FAK pathway activation between stimulated and unstimulated cell lysates, monitoring responses during adhesion experiments, and investigating changes associated with cell motility.

Each package contains 200 µl. In immunoblot workflows, the antibody can be paired with a suitable anti-rabbit secondary reagent and detection system. Reliable interpretation depends on phosphorylation conditions, sample preparation, and normalization against total PTK2 and appropriate loading controls.
