Anti-RAB11B Antibody [KT81]

The Anti-RAB11B Antibody [KT81] from Antibodies.com is a rat monoclonal antibody raised against RAB11B, a small Ras-related GTPase of approximately 24.5 kDa that regulates intracellular vesicle trafficking and the recycling endosome pathway. This unconjugated IgG2b reagent is supplied as a liquid preparation in 100 µg aliquots and is validated for Western blot (WB) and immunofluorescence (IF) workflows on mouse samples. Researchers commonly deploy clone KT81 to investigate endocytic recycling, cargo sorting, and receptor trafficking in cell biology studies, where it is typically applied at working dilutions of 1:500–1:2000 for WB and 1:50–1:200 for IF on fixed cells. The antibody is provided in a vial and should be stored at -20 °C for long-term stability, with single-use aliquots kept refrigerated to avoid repeated freeze-thaw cycles. In immunofluorescence, the RAB11B signal characteristically appears as a cytoplasmic punctate pattern that overlaps with pericentriolar recycling endosomes, making it a useful marker for tracking membrane cargo flux and transferrin receptor recycling.
