CD44 is a transmembrane glycoprotein that serves as the principal cell surface receptor for hyaluronic acid, playing fundamental roles in cell adhesion, migration, and signaling. This multifunctional molecule is particularly significant in cancer biology, where it contributes to tumor progression, metastasis, and the maintenance of cancer stem cell populations. CD44's involvement in lymphocyte homing and immune cell trafficking also makes it a valuable target for immunological research.
This recombinant monoclonal antibody, clone 19H12, offers the reproducibility and consistency that demanding research applications require. Produced using recombinant technology with a sequence-defined approach, it eliminates the lot-to-lot variability often encountered with traditional hybridoma-derived antibodies, ensuring your experimental conditions remain stable across long-term studies and multi-site collaborations.
Validation across multiple techniques demonstrates this antibody's versatility in your workflow. Western blot analysis confirms specific detection at the predicted 81 kDa molecular weight in A549 lung carcinoma, MCF7 breast cancer, and HepG2 hepatocellular carcinoma cell lysates, providing confidence when working with these commonly used human cancer models. Immunohistochemistry staining has been successfully performed on paraffin-embedded human rectal cancer and lung cancer tissues, enabling investigation of CD44 expression patterns in clinical specimens. For cellular localization studies, immunofluorescence validation in HeLa cells reveals clear staining patterns, while flow cytometry analysis confirms reliable surface detection on the same cell line.
Whether you're investigating cancer stem cell markers, exploring metastatic mechanisms, or characterizing immune cell populations, this antibody provides a dependable tool for advancing your understanding of CD44 biology across multiple experimental platforms.
