Anti-ANXA4 Antibody

Raised in rabbit and supplied by Antibodies.com as 100 µl of unconjugated antiserum, this polyclonal antibody specifically recognizes Annexin A4 (ANXA4), a calcium-dependent phospholipid-binding protein of the annexin family that participates in membrane organization, vesicular trafficking, exocytosis, and calcium-mediated ion channel regulation. The reagent is validated for Western blot (WB) and immunofluorescence (IF) workflows on human, mouse, and rat samples, with the polyclonal format providing multi-epitope recognition useful when probing endogenous ANXA4 levels across tissues and experimental conditions. Published research links ANXA4 expression to several carcinoma contexts, including renal and colorectal tumors, and to epithelial ion transport, making this product a practical tool for cell biology, cancer biomarker discovery, and membrane-trafficking studies. Because the antibody is unconjugated, it can be paired with multiple secondary reagents or custom labeling schemes to match the detection platform. For long-term use, aliquot the antiserum to minimize freeze-thaw cycles and store protected from light to preserve activity.
