General description

BIOCHEMISTRY:

p I = 7.0

Specificity

This specificity of this antibody is equivalent to that of CD19 monoclonal antibodies (Zola et al., 1988, 1989), based on comparative studies, antigen recognition and positive reaction with a CD19 transfected cell line. It detects a 96 kD single chain glycoprotein on the surface of human B lineage cells, including pre-B cells. B cells can be detected in peripheral blood and tissues. The antibody reacts with most B cell malignancies including chronic lymphocytic leukemia and most lymphomas, but not multiple myeloma.

Cell reactivity:

Normal:Stains all B lymphocytes in peripheral blood and spleen. Negative on granulocytes, monocytes, platelets, erythrocytes and T lymphocytes.

Clinical:

B cell chronic lymphocytic leukemia (B-CLL) +

Pro lymphocytic leukemia (PLL +

Hairy cell leukemia (HCL) +

Common acute lymphoblastic leukemia (CALL) +

Pre-B acute lymphoblastic leukemia (pre-B-ALL) +

NULL-acute lymphoblastic leukemia (NULL-ALL) +

T-acute lymphoblastic leukemia (T-ALL) -

T-common lymphocytic leukemia (T-CLL -

This antibody is useful for enumerating normal B lymphocytes and typing B cell malignancies by flow cytometry.

SUGGESTED USAGE

Flow cytometry - use 10 μl direct from the vial per 100 μl of whole blood, or 1 x 10E(6) peripheral blood mononuclear cells (PBMC) in 100 μl buffer.

Linkage

Replaces: CBL141P

Physical form

Purified from mouse ascitic fluid. R-Phycoerythrin conjugated. The antibody is supplied in 1.0ml PBS 0.01M, Sodium Azide 0.1%, pH 7.1, 0.2% BSA. The characteristics of each lot are tested by electrophoresis and flow cytometry.

Storage and Stability

Store at 2 to 8°C, for up to 6 months. DO NOT FREEZE. Protect from light.

WARNING: The monoclonal reagent solution contains 0.1% sodium azide as a preservative. Due to potential hazards arising from the build up of this material in pipes, spent reagent should be disposed of with liberal volumes of water.
