Anti-LPO Antibody

This polyclonal primary antibody from Antibodies.com targets lactoperoxidase (LPO), a heme-containing peroxidase enzyme secreted in epithelial tissues and exocrine secretions where it contributes to innate antimicrobial defense through the thiocyanate–hydrogen peroxide–hypothiocyanite system. Raised in rabbit and supplied as an unconjugated IgG preparation at 50 µl, the reagent is validated for Western Blot (WB) detection of LPO in human and mouse sample lysates. The polyclonal format allows recognition of multiple epitopes across the target protein, which can improve signal robustness when probing endogenous expression in mucosal, salivary, glandular, and milk-derived samples. The recommended workflow pairs the antibody with standard HRP-conjugated anti-rabbit secondary reagents and chemiluminescent or chromogenic detection. Aliquots should be stored refrigerated at 2 to 8 degrees C and protected from repeated freeze-thaw cycles to preserve immunoglobulin binding activity over extended use. Researchers investigating epithelial innate immunity, oral and airway host defense, mammary gland biology, or comparative LPO expression between human and murine models can deploy this reagent in cell lysate and tissue homogenate Western Blot assays, with cross-reactivity demonstrated against both species listed in the reactivity panel.
