Anti-Mucin 4 Antibody

Mucin 4 (MUC4) is a large membrane-bound mucin glycoprotein implicated in epithelial lubrication, cell signaling, and tumor progression when overexpressed in pancreatic, ovarian, breast, and lung carcinomas. This unconjugated rabbit polyclonal antibody from Antibodies.com recognizes epitopes on the MUC4 extracellular region, supporting Western blot studies of full-length and variant isoforms in human, mouse, and rat samples.

Each vial contains 100 µl of antibody at 1 mg/ml, formulated in PBS with 0.1% Sodium Azide as a preservative and 50% Glycerol as a cryoprotectant for reliable storage. The polyclonal format offers multi-epitope recognition, useful when probing MUC4 expression across different cell lines and primary tissue lysates, and the unconjugated status allows pairing with anti-rabbit HRP or fluorescent secondary reagents of the researcher's choice.

The reagent is validated for WB applications only and is shipped as a single-use aliquot. Researchers should aliquot upon arrival to avoid repeated freeze-thaw cycles and maintain antibody integrity for ongoing Western blot experiments.
