The solute carrier family 16 member 9 (SLC16A9) is a transmembrane protein belonging to the monocarboxylate transporter (MCT) family, which facilitates the transport of metabolites like lactate, pyruvate, and ketone bodies across cell membranes. SLC16A9 is implicated in diverse physiological processes, including energy metabolism, pH regulation, and cellular signaling. Its expression has been detected in multiple tissues, such as the prostate, liver, and kidney, with emerging roles in diseases like cancer and metabolic disorders. SLC16A9 antibodies are essential tools for studying the protein's expression, localization, and function in both normal and pathological contexts. These antibodies are typically validated for applications such as Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF), enabling researchers to investigate tissue-specific distribution or altered expression in disease models. Recent studies highlight SLC16A9's potential as a biomarker or therapeutic target, particularly in prostate cancer and metabolic syndromes. Reliable SLC16A9 antibodies are crucial for elucidating its structural interactions, substrate specificity, and regulatory mechanisms. Researchers often prioritize antibodies with demonstrated specificity through knockout controls or peptide blocking assays. As interest in SLC16A9 grows, its antibody-based profiling continues to support advances in understanding metabolic dysregulation and oncogenic pathways.
