CD44 Antibody / HCAM

• Catalog Number: orb749333
• Category: Antibodies
• Description: This antibody recognizes a cell surface glycoprotein of 80-95kDa, called CD44, or HCAM, on lymphocytes, monocytes, and granulocytes (Leucocyte Typing Workshop V). Its epitope is resistant to digestion by trypsin and chymotrypsin. The CD44 family of glycoproteins exists in a number of variant isoforms, the most common being the standard 85-95kDa or hematopoietic variant (CD44-s). Higher molecular weight isoforms are described in epithelial cells (CD44-v), which are believed to function in intercellular adhesion and stromal binding. HCAM antibody immunostaining is commonly used for the discrimination of urothelial transitional cell carcinoma in-situ from non-neoplastic changes in the urothelium.
• Clonality: Monoclonal
• Species/Host: Mouse
• Isotype: Mouse IgG2a, kappa
• Conjugation: Unconjugated
• Reactivity: Human
• Buffer/Preservatives: 0.2 mg/ml in 1X PBS with 0.1 mg/ml rAlbumin (US sourced) and 0.05% sodium azide
• Purity: Protein G affinity chromatography
• Immunogen: Stimulated human leukocytes were used as the immunogen for this CD44 / HCAM antibody.
• Tested applications: FACS, IF, IHC-P, WB
• Dilution range: Flow cytometry: 2-4ug/million cells,Immunofluorescence: 2-4ug/ml,Western blot: 1-2ug/ml,Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT
• Application notes: The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the HCAM antibody to be titered up or down for optimal performance.1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 minutes.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
