Anti-IGFBP4 Antibody

IGFBP4 is a secreted binding protein that modulates the activity of insulin-like growth factors IGF-1 and IGF-2, influencing cell proliferation, differentiation, and metabolic signaling across many tissues. This rabbit polyclonal antibody targets IGFBP4 and is supplied by Antibodies.com at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, packaged as a 100 µl vial for convenient bench use.

The reagent is validated for western blot and immunohistochemistry workflows and shows reactivity against human, mouse, and rat samples, making it a flexible tool for cross-species studies of growth factor biology, tumor microenvironment research, and tissue-level expression profiling. Because the antibody is unconjugated, it can be paired with secondary detection systems of the researcher's choice, including HRP, fluorophore, or biotin conjugates selected to match a specific imaging or blotting protocol.

Store refrigerated and protect from light to preserve activity, and avoid repeated freeze-thaw cycles by aliquoting on first use. The polyclonal format provides recognition of multiple epitopes on IGFBP4, which can be advantageous when working with denatured lysates or formalin-fixed paraffin-embedded sections.
