Anti-LKB1 Antibody

LKB1, also called serine/threonine kinase 11 (STK11), acts as a tumor-suppressor kinase central to AMPK activation, cell polarity, and metabolic stress responses, with germline mutations implicated in Peutz-Jeghers syndrome and somatic loss commonly reported in non-small-cell lung cancer. The Antibodies.com anti-LKB1 polyclonal reagent is a rabbit-hosted IgG preparation supplied as 100 µl of unconjugated antibody at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, validated for Western blot, immunohistochemistry, and immunofluorescence workflows across human, mouse, and rat samples. The unconjugated format supports flexible secondary labeling or direct detection, while the glycerol-containing buffer stabilizes the antibody through repeated freeze-thaw handling and supports storage at -20 °C in aliquoted form for long-term use.
