Anti-CD44 Antibody

Targeting the CD44 cell-surface glycoprotein, this unconjugated mouse IgM monoclonal reagent recognizes the human antigen and is validated for Western blot, immunohistochemistry, and flow cytometry workflows. Supplied by Antibodies.com within the Primary Antibodies portfolio, the antibody is provided as a 50 µl volume formulated in TBS (pH 7.4) with 1% BSA, 40% glycerol, and 0.05% sodium azide as preservative.

CD44 functions as the principal cell-surface receptor for hyaluronic acid and participates in cell adhesion, migration, and lymphocyte homing, and it is widely used as a marker of cancer stem-like populations across solid tumor types. The unconjugated format gives researchers freedom to pair the reagent with secondary detection systems of their choice, supporting chromogenic IHC staining on formalin-fixed tissue, immunoblot detection of membrane-associated proteins, and surface-marker profiling by FC.

For routine handling, store the antibody at -20°C in working aliquots to limit repeated freeze-thaw cycles, with short-term storage at 4°C acceptable for in-use vials. The reagent is reactive with human CD44 and is intended for research use only.
