Anti-OPN Antibody

Raised in rabbit against osteopontin (OPN), this unconjugated polyclonal antibody targets a secreted phosphoglycoprotein encoded by the SPP1 gene. OPN is implicated in bone remodeling, cell adhesion and migration, and modulation of immune cell signaling, and is expressed across tissues including bone matrix, renal tubules, and activated macrophages.

From Antibodies.com, the reagent is supplied as 100 µl of unconjugated antiserum and is validated for western blot, immunohistochemistry, and ELISA workflows. It has been characterized for reactivity against human, mouse, and rat samples, supporting comparative studies of osteopontin expression in mineralization, inflammatory signaling, and tumor microenvironment research.
