Anti-PIBF1 Antibody

PIBF1 (Progesterone-Induced Blocking Factor 1) is a multifunctional protein best known for mediating the immunomodulatory actions of progesterone during pregnancy. This polyclonal antibody, raised in rabbit and offered by Antibodies.com, recognizes endogenous PIBF1 in human, mouse, and rat samples, supporting comparative studies across model systems. The unconjugated format gives researchers flexibility to pair the reagent with custom secondary antibodies, fluorophores, or enzyme reporters as their assay design requires.

Validated for western blot and immunohistochemistry, the antibody detects native PIBF1 in cell lysates and in fixed tissue sections. It is widely used in trophoblast biology, decidual immune cell function, and tumor microenvironment research, where PIBF1 expression has been linked to malignant progression in breast, endometrial, and other cancers. Supplied as 100 µl of polyclonal antiserum in a vial, the volume is sufficient for multiple western blot membranes or several dozen IHC slides depending on dilution and detection method.

Target: PIBF1. Reactivity: Human, Mouse, Rat. Host: Rabbit. Clonality: polyclonal. Conjugate: unconjugated. Applications: western blot, immunohistochemistry.
