CD34 Class III Mouse Monoclonal Antibody [Clone ID: 4H11]

Specifications

Product Data
Clone Name	4H11
Applications	FC
Recommend Dilution	Indirect immunofluorescence analysis by Flow cytometry (1:200 as starting point).
Reactivity	Human
Host	Mouse
Clonality	Monoclonal
Immunogen	Permanent human cell line derived from peripheral leucocytes of a patient suffering from chronic myeloid leukaemia
Specificity	This antibody reacts with Class III epitope on CD34 (Mucosialin), a 110-115 kDa monomeric transmembrane phosphoglycoprotein expressed on hematopoietic progenitors cells and on the most pluripotential stem cells; it is gradually lost on progenitor cells. The antibody 4H11[APG] completely blocks binding of Class II antibody QBEnd10 and Class III antibodies BIRMA K3 and 8G12 on KG1a cell line.
Isotype	IgG1
Formulation	Phosphate buffered saline (PBS) with 15 mM sodium azide, approx. pH 7.4 Label: Biotin State: Liquid purified Ig fraction Label: The purified antibody is conjugated with Biotin-LC-NHS under optimum conditions. The reagent is free of unconjugated biotin.
Concentration	lot specific
Conjugation	Biotin
Storage Condition	Store the antibody undiluted at 2 - 8 °C. DO NOT FREEZE!
Gene Name	CD34 molecule
Database Link	Entrez Gene 947 Human UniProt ID P28906
Background	CD34 is a highly glycosylated monomeric 111-115 kDa surface protein, which is present on many stem cell populations. It is a well established stem cell marker, though its expression on human hematopoietic stem cells is reversible. CD34 probably serves as a surface receptor that undergoes receptor-mediated endocytosis and regulates adhesion, differentiation and proliferation of hematopoietic stem cells and other progenitors. CD34 expression is likely to represent a specific state of hematopoietic development that may have altered adhering properties with expanding and differentiating capabilities in both in vitro and in vivo conditions.
Synonyms	Hematopoietic progenitor cell marker

Protein Families	Adult stem cells, Cancer stem cells, Druggable Genome, Embryonic stem cells, ES Cell Differentiation/IPS, Transmembrane
Protein Pathways	Cell adhesion molecules (CAMs), Hematopoietic cell lineage
