Anti-CAB39 Antibody

Produced in rabbit and validated for western blot and immunohistochemistry, this unconjugated primary antibody from Antibodies.com targets the human CAB39 protein, a calcium-binding scaffold that partners with STRADα to activate the LKB1 kinase, which in turn phosphorylates and switches on AMPK, a central regulator of cellular energy homeostasis. The reagent is supplied as 100 µl of polyclonal antisera in a single-use vial and can be paired with a user-selected secondary antibody for chromogenic, chemiluminescent, or fluorescent detection of CAB39 in cell lysates, tissue sections, and subcellular fractionation samples. Because CAB39 is required for full LKB1 activity, this antibody is a useful marker in studies of tumor suppressor signaling, metabolic disease, and cell polarity research, and the product is intended for research use only.
