Anti-Periostin Antibody

This polyclonal antibody from Antibodies.com is raised in rabbit and targets human Periostin, a secreted matricellular protein implicated in extracellular matrix remodeling, wound healing, and fibrotic disease. The unconjugated reagent is supplied at 100 µg and is validated for Western Blot (WB) and Immunohistochemistry (IHC) workflows. Researchers investigating tissue fibrosis, asthma airway remodeling, cardiac injury response, or tumor microenvironment biology routinely probe POSTN expression to characterize mesenchymal activity and stromal contributions to disease progression. As a polyclonal reagent, the antibody recognizes multiple epitopes across the target, which can be advantageous when detecting post-translational modifications or splice variants that may obscure single-epitope recognition. The Human reactivity profile suits work on patient-derived biopsies, cell line models, and primary fibroblasts or epithelial cultures relevant to respiratory, cardiovascular, and oncology research.
