Product Specific Information
Description: The eBio1D3 monoclonal antibody reacts with mouse CD19, a 95 kDa transmembrane glycoprotein. CD19 is expressed by B cells during all stages of development excluding the terminally differentiated plasma cells. Follicular dendritic cells also express CD19. Together CD21, CD81, MHC class II, and CD19 form a multimolecular complex that associates with the BCR. Signaling through CD19 induces tyrosine phosphorylation, calcium flux and proliferation of B cells.
Applications Reported: This eBio1D3 (1D3) antibody has been reported for use in flow cytometric analysis.
Applications Tested: This eBio1D3 (1D3) antibody has been tested by flow cytometric analysis of mouse splenocytes. This may be used at less than or equal to 1.0 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Brilliant Violet™ 480 (BV480) is a dye that emits at 479 nm and is intended for use on cytometers equipped with a violet (405 nm) laser. Please make sure that your instrument is capable of detecting this fluorochrome.
When using two or more Super Bright, Brilliant Violet™, Brilliant Ultra Violet™, or other polymer dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product # SB-4401-42) or Brilliant Stain Buffer™ (Product # 00-4409-75) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer or Brilliant Stain Buffer for more information.
Our internal testing suggests that Brilliant Violet™ 480 (BV480) is not compatible with methanol-based fixation.

Target Information
CD19 is a member of the immunoglobulin superfamily, characterized by two Ig-like domains, and is expressed on B cells throughout all stages of development, excluding terminally differentiated plasma cells. It is also expressed on follicular dendritic cells and has been observed on myeloid leukemia cells, particularly those of monocytic lineage. CD19 is considered the earliest and broadest B cell-restricted antigen, and its expression is found in all B cell precursor leukemias. CD19 forms a multimolecular complex with CD21, CD81, Leu13, MHC class II, and the B cell receptor (BCR), playing a crucial role in B cell signaling. As a signal-amplifying coreceptor for the BCR, CD19 lowers the threshold for antigen receptor-dependent stimulation, allowing B cells to respond specifically and sensitively to various antigens through low-affinity antigen receptors. Signaling through CD19 induces tyrosine phosphorylation, calcium flux, and proliferation of B cells. Beyond its role as a BCR coreceptor, CD19 can also signal independently of BCR co-ligation, serving as a central regulatory component upon which multiple signaling pathways converge. This makes CD19 an important functional regulator of both normal and malignant B cell proliferation. Mutations in the CD19 gene can result in hypogammaglobulinemia, a condition characterized by low levels of immunoglobulins, while CD19 overexpression can lead to B cell hyperactivity. CD19 is expressed on 100% of peripheral B cells, as defined by the expression of kappa or lambda light chains, underscoring its significance in B cell function and immune regulation.
