Aquaporin-5 (AQP5) serves as a critical water channel protein predominantly expressed in secretory epithelia, where it facilitates rapid transcellular water transport essential for fluid secretion in salivary glands, lacrimal glands, and pulmonary alveolar cells. Dysregulation of AQP5 expression and localization has been implicated in conditions ranging from Sjögren's syndrome to various malignancies, making it a significant target for researchers investigating epithelial physiology, secretory dysfunction, and cancer biology.
This recombinant monoclonal antibody, clone 22E9, offers the experimental consistency that demanding research protocols require. Produced using recombinant technology with a defined sequence, this rabbit IgG eliminates the lot-to-lot variability inherent in traditional hybridoma-derived antibodies, ensuring that your immunohistochemistry results remain reproducible across extended studies and multi-site collaborations.
Validation in human tissues demonstrates robust performance in immunohistochemistry applications. Testing in paraffin-embedded human salivary gland tissue confirms reliable detection in a tissue type where AQP5 plays a well-characterized physiological role in saliva production. Additionally, validation in human endometrial cancer tissue extends the antibody's utility to oncology research, where AQP5 expression patterns may inform tumor characterization studies. Both validations employed citrate buffer antigen retrieval at pH 6.0 with overnight primary antibody incubation, providing a reproducible starting protocol that researchers can adapt to their specific workflows. Working dilutions of 1:50 to 1:200 offer flexibility for optimization across different tissue preparations.
Whether investigating normal secretory epithelial function or exploring AQP5's emerging roles in signal transduction pathways and tumor biology, this affinity-purified antibody provides a dependable tool for your immunohistochemistry studies in human specimens.
