Description:
Studies on normal lymphocytes, leukemic cells and cell lines indicate it is a marker for a limited segment of the B cell maturation pathway(2,3). This glycoprotein is expressed in varying degrees on normal circulating B-cells, chronic B-cell leukemia (B-CLL), prolymphocytic leukemia (PLL) and other B cell neoplasias (4–1)2. It labels the same population as CD22 antibodies but reacts with a different antigen(5). Cell reactivity: Stains peripheral blood B lymphocytes and tonsil B lymphocytes. (1).
This antibody can be used for the differentiation of PLL from B-CLL. It is also useful in confirmation of the diagnosis of other disorders such as HCL, HCL-V and SLVL. Useful for the detection of residual disease in patients undergoing treatment for these disorders.
Applications:
Suitable for use in Flow Cytometry. Other applications have not been tested.
Recommended Dilution:
Flow Cytometry: Neat. Use 10ul per 100ul of whole blood, or 1x10e6 peripheral blood mononuclear cells (PBMC) in 100ul buffer.
Optimal dilution to be determined by the researcher.
Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50), aliquot and store at -20°C. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
