Anti-LAPTM4B Antibody

The polyclonal rabbit IgG reagent targets the lysosomal transmembrane protein LAPTM4B, a four-pass membrane glycoprotein implicated in autophagy regulation, endosomal trafficking, and tumor cell proliferation. Supplied in unconjugated format for flexible downstream labelling, the antibody is provided as 100 µl of liquid and validated for Western blot workflows on lysates from human and rat origin samples. Researchers commonly deploy this reagent to investigate LAPTM4B overexpression in hepatocellular carcinoma, breast cancer, ovarian carcinoma, and other solid tumor models, alongside its contribution to multidrug resistance phenotypes. Distributed by Antibodies.com as part of the Primary Antibodies catalog, the reagent offers a polyclonal response profile that recognizes multiple epitopes across the LAPTM4B sequence, supporting reproducible detection under standard SDS-PAGE and immunoblotting conditions. Aliquot upon arrival to minimize freeze-thaw cycles and preserve antibody titer for repeated blotting experiments.
