Description:
Anti-CD34 Class I, clone B1-3C5
Trade Name:
Chemicon (Millipore)
Specificity:
This antibody belongs to CD34 (assigned by the Third International Workshop on Leukocyte Differentiation Antigens, Oxford, 1987; Hogg & Horton, 1987). It reacts with a 120kD glycoprotein found on progenitor cell populations in human bone marrow and foetal liver (Katz et al., 1985). This antigen is normally restricted to immature human haemopoietic precursor cells (Peschel & Koller, 1989).
Cell reactivity (Tindle et al., 1985):
Normal: No reaction with normal peripheral lymphocytes, granulocytes, monocytes, erythrocytes and platelets. Reacts with <4% of cells in normal bone marrow.
Clinical: Reaction
Acute myeloid leukemia (AML, M1 and M2) positive
Null lymphoblastic leukemia (Null ALL) positive
Common acute lymphoblastic leukemia (CALL) positive
Myeloblastic and lymphoblastic crises of chronic
granulocytic leukemia (CGL) positive
Chronic myeloid leukemia (CML) negative
T cell acute lymphoblastic leukemia (TALL) negative
B cell acute lymphoblastic leukemia (BALL) negative
Chronic lymphocytic leukemia (CLL) negative
Cell lines:
Reacts with early myeloblast line KG1. No reaction with null, B or T lymphoid, erythroid or later myeloid cell lines.

Immunogen:
KG1 human acute myelogenous cell line.
Clone:
B1-3C5
Isotype:
IgG1
Species Reactivity:
Human
Application Notes:
Identification of CD34 positive cells is important for the diagnosis and classification of acute myeloid leukemia (AML). It is especially useful in patients with poorly differentiated myeloblasts, as well as in myeloblastic crises of chronic granulocytic leukemia. It has been recommended that this antibody be used as part of a panel for screening of leukemia (Batinic et al., 1989).
SUGGESTED USAGE DILUTION
1. Flow cytometry and indirect immunofluorescence 1:25
Dilute with isotonic buffer. Use 50 μl of diluted antibody per 1 x 10E6 peripheral blood mononuclear cells (PBMC) or bone marrow cells in 100 μl of buffer.
2. Indirect immunoperoxidase staining - the final dilution will depend on the assay conditions and detection system employed. However, a dilution of at least 1:25 will be applicable to most commonly used systems.
