Anti-CD44 Antibody

Rabbit-derived polyclonal IgG from Antibodies.com targets CD44, the cell-surface glycoprotein that mediates hyaluronate binding, leukocyte homing, and cell-matrix adhesion. The unconjugated reagent is calibrated for Western blot and immunohistochemistry on human and mouse specimens, making it useful for tracking epithelial-to-mesenchymal transition, tumor invasion, and hematopoietic stem cell trafficking. Each vial contains 100 µl of antibody at 1 mg/ml, prepared in phosphate buffered saline (PBS) supplemented with 0.05% sodium azide at approximately pH 7.2, ready for use with HRP-, biotin-, or fluorophore-conjugated secondary reagents. Researchers can titrate the stock for chromogenic staining of formalin-fixed paraffin-embedded tissue sections or for probing whole-cell lysates under reducing conditions.
