Product nameAnti-CD34 antibody [QBEND-10]
See all CD34 primary antibodies -
DescriptionMouse monoclonal [QBEND-10] to CD34
-
Host speciesMouse
-
SpecificityThis antibody recognizes the CD34 antigen, some cross reactions with vascular associated adventitia and some basement membranes. Ultrastructure studies, using an indirect immuno-gold technique on ultra thin sections of human umbilical artery, have revealed that this antigen is associated to a degree with the basoluminal surfaces of endothelium and shows a slight reaction with an intracytoplasmic vesicular compartment. Predominant staining is on the endothelial cell membrane. QBEND-10 immunoprecipitates a glycoprotein with a relative MW 110kD expressed on haematopoietic cells and on the established myeloid leukaemic cell line KG1A.

Tested applicationsSuitable for: Flow Cyt, IHC-Fr, IP, IHC-P, WBmore details
-
Species reactivityReacts with: Human, Cynomolgus monkey, Rhesus monkey
Does not react with: Rat, Sheep, Cow, Dog -
Immunogen
Other Immunogen Type corresponding to CD34. Human endothelial vesicles
-
EpitopeThis antibody's target epitope is distinct from those of other anti-CD34 reactive mabs as demonstrated by its lack of sensitivity to neuraminidase treatment, and fluorescence staining profiles during flow cytometry analysis of target cell populations.

Positive control
- tonsil, bone marrow

Target
-
FunctionPossible adhesion molecule with a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. Could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. Presents carbohydrate ligands to selectins.
-
Tissue specificitySelectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues.
-
Sequence similaritiesBelongs to the CD34 family.
-
Developmental stageOn early hematopoietic progenitor cells.
-
Post-translational
modificationsHighly glycosylated.
Phosphorylated on serine residues by PKC. -
Cellular localizationMembrane.

Flow Cytometry - Anti-CD34 antibody [QBEND-10] (ab8536)Overlay histogram showing Jurkat cells stained with ab8536 (red line). The cells were fixed with methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab8536, 1/50 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a significantly decreased signal in Jurkat cells fixed with 4% paraformaldehyde (10 min) used under the same conditions.
Please note that Abcam do not have data for use of this antibody on non-fixed cells. We welcome any customer feedback. -

Tissue was fixed with formaldehyde and blocked with 2% BSA for 10 minutes at 21°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/2000 in blocking buffer) for 16 hours at 21°C. A Biotin-conjugated goat anti-mouse IgG polyclonal (1/300) was used as the secondary antibody.
