Description

General description

CD19 is a transmembrane glycoprotein of Ig superfamily expressed by B cells from the time of heavy chain rearrangement until plasma cell differentiation. It forms a tetrameric complex with CD21 (complement receptor type 2), CD81 (TAPA-1) and Leu13. Together with BCR (B cell antigen receptor), this complex signals to decrease B cell treshold for activation by the antigen. Besides being signal-amplifying coreceptor for BCR, CD19 can also signal independently of BCR coligation and it turns out to be a central regulatory component upon which multiple signaling pathways converge. Mutation of the CD19 gene results in hypogammaglobulinemia, whereas CD19 overexpression causes B cell hyperactivity.

Specificity

The antibody LT19 reacts with an extracellular epitope of CD19 (B4), a 95 kDa type I transmembrane glycoprotein (immunoglobulin superfamily) expressed on B lymphocytes and follicular dendritic cells; it is lost on plasma cells.

Immunogen

Daudi human Burkitt lymphoma cell line

Physical form

Stabilizing phosphate buffered saline (PBS), pH 7.4, 15 mM sodium azide

Preparation Note

Purified antibody is conjugated with activated tandem dye of allophycocyanin-cyanine 7 (APC-Cy7) under optimum conditions and unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.

Storage and Stability

Store at 2-8°C. Protect from prolonged exposure to light. Do not freeze.

Other Notes

The antibody solution should be gently mixed before use.
