Anti-Crk2 (phospho-Try221) Antibody

For immunohistochemistry-based detection of phosphorylated Crk2, this unconjugated rabbit polyclonal antibody from Antibodies.com was raised against a synthetic phosphopeptide corresponding to residue 221 of Crk2. Supplied at 1 mg/ml in phosphate buffered saline containing 0.05% sodium azide at pH approximately 7.2, the 100 µl format supports multiple staining runs on formalin-fixed paraffin-embedded tissue sections. Reactive against human, mouse, and rat samples, the reagent enables comparative studies of Crk2 phosphorylation in adhesion, cytoskeletal remodeling, and growth-factor receptor signaling across model systems. Divide into smaller aliquots before storage to limit repeated freeze-thaw exposure of the working solution.
