Anti-CD44 Antibody

The CD44 antigen is a broadly expressed transmembrane glycoprotein that serves as the principal cell-surface receptor for hyaluronic acid and participates in lymphocyte activation, recirculation, hematopoiesis, and tumor metastasis. This rabbit polyclonal antibody from Antibodies.com is raised against CD44 and validated for Western blot and ELISA workflows.

The unconjugated format gives laboratories flexibility for secondary antibody pairing and downstream labeling, supporting immunoprecipitation, immunohistochemistry, and similar detection protocols. The reagent is reactive against human, mouse, and rat samples, enabling cross-species studies in cell adhesion, oncology, and stem cell biology research where CD44 is widely used as a cancer stem cell and tumor-progression marker.

Supplied as 100 µl of polyclonal antiserum, the antibody provides sufficient volume for multiple optimization experiments and ongoing screening campaigns in academic and translational settings. Best results are typically obtained by titrating the antibody against the target species and tissue of interest, with appropriate positive and negative controls to confirm specificity.
