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.
Immunogen
Daudi human Burkitt lymphoma cell line
Biochem/physiol Actions
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.
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.
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.
