CD34 antibody

Catalog No. ABIN3026497

Product Details anti-CD34 Antibody

Target: CD34

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD34 antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunofluorescence (IF), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Characteristics: This antibody recognizes a carbohydrate epitope on a single chain, transmembrane, heavily glycosylated protein of 90-120 kDa, which is identified as CD34 (VI international workshop on human differentiation antigens). Its expression is a hallmark for identifying pluripotent hematopoietic stem or progenitor cells. Its expression is gradually lost as lineage committed progenitors differentiate. CD34 is a marker of choice for staining blasts in acute myeloid leukemia. In addition, it is expressed by soft tissue tumors, such as solitary fibrous tumor and gastrointestinal stromal tumor. CD34 expression is also found in vascular endothelium. Additionally, proliferating endothelial cells overexpress this molecule than the non-proliferating endothelial cells. Anti-CD34 labels > 85 % of angiosarcoma and Kaposi s sarcoma, but shows low specificity.

Purification: Protein G affinity chromatography

Immunogen: A detergent solubilized vesicular suspension prepared from human term placenta (QBEnd/10) and recombinant full-length human protein (HPCA1/763) were used as the immunogen for the CD34 antibody cocktail.

Clone: QBEnd-10-HPCA1-763

Isotype: IgG

Application Details

Application Notes: Optimal dilution of the CD34 antibody cocktail should be determined by the researcher.

1. Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10  mM Citrate buffer,  pH 6.0, for 10-20 min followed by cooling at RT for 20 min.
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.\. Flow Cytometry: 0.5-1 μg/million cells in 0.1ml,Immunofluorescence: 0.5-1 μg/mL,Immunohistochemistry (FFPE): 0.25-0.5 μg/mL for 30 min at RT (1),Prediluted format: incubate for 30 min at RT (2)

Restrictions: For Research Use only
