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 common lymphocytic leukemia (T-CLL) -

This Anti-Human B cells CD19 Antibody, clone FMC63 is validated for use in FC, IF for the detection of CD19.
This antibody is useful for enumerating normal B lymphocytes and typing B cell malignancies by flow cytometry and immunofluorescence.

SUGGESTED USAGE DILUTION

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) in 100 μl buffer.

Linkage

Replaces: CBL141

Physical form

Format: Purified
Purified from mouse ascitic fluid. The antibody is supplied in 25 mM Tris-HCl buffer, 0.4 M NaCl, pH 8.0, containing 0.2% bovine serum albumin and 0.1% sodium azide. 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. For prolonged periods, store below -20°C in undiluted aliquots. AVOID REPEATED FREEZE/THAW CYCLES.

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.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
