CD19 Antibody (SJ25-C1) [Biotin] Summary

The antibody reacts with the CD19 antigen.
The CD19 antigen is the most broadly expressed surface marker for B-cells appearing at the earliest stages of B-cell differentiation. The CD19 antigen is expressed at all stages of B-cell maturation and is lost during terminal B-cell differentiation to plasma cells.
Protein A or G purified

Application Notes
The antibody can be used for flow cytometry.This antibody has been titred for application in flow cytometry. 5 μl is the maximum amount of reagent required for 1 x 106 cells. Lesser amounts of antibody may be sufficient and it is recommended that the customer determine the optimum amount of antibody for each applica­tion. See further instructions for use A.

Reactivity Notes



Fluorochrome conjugates should be stored in the dark and direct exposure to light should be avoided during handling and cell staining.


CD19 is a member of the immunoglobulin superfamily and has two Ig like domains. The CD19 molecule is expressed on 100% of the peripheral B cells as defined by expression of kappa or lamda light chains. It is expressed on approximately 10% of normal human peripheral blood cells and approximately 60% of splenic lymphocytes. It is not expressed on granulocytes, monocytes or T cells as defined by CD3 expression. CD19 defines a pan B antigen which is expressed from the earliest stages of B progenitor development, but is lost on terminal differentiation to plasma cells. It may also be present on some early myeloid progenitors, particularly those of the monoblastic type. The CD19 antigen is expressed on approximately 12% of peripheral blood lymphocytes. It appears to be expressed on myeloid leukemia cells, particularly those of monocytic lineage. Leukemia phenotype studies have demonstrated that the earliest and broadest B cell restricted antigen is the CD19 antigen.
