cFluor<sup>®</sup> V755 Anti-Human CD19 (SJ25C1)
The mouse monoclonal antibody clone SJ25C1 binds to human CD19, a 95 kDa glycoprotein that acts as a co-receptor, along with CD21 (CR2), CD81 (TAPA-1), and CD225 (Leu13), in support of the functional B cell receptor (BCR). This complex provides antigen-specific recognition and subsequent activation of B cells to proliferate and differentiate into antibody-secreting cells (plasma cells) or memory B cells, which are crucial for secondary antigen encounters. Upon activation and tyrosine phosphorylation, the CD19 molecule can provide an anchor for cytoplasmic signaling proteins such as GRB2, SOS, or PLCG2. CD19 is a lineage-differentiation marker, as its expression is detectable at the earliest B cell stages, through development, and is finally lost upon transition to mature plasma cells. It is also present on follicular dendritic cells and absent on T cells. Signaling through CD19 induces tyrosine phosphorylation, calcium flux, and proliferation of B cells. It is reported that The SJ25C1 antibody and the HIB19 monoclonal antibody recognize overlapping epitopes.
PRODUCT DETAILS

Specificity: CD19
Reactivity: Human
Format: cFluorĀ® V755
Isotype: Mouse IgG1, k
Tested Dilution: 5 ĀµL/Test
Application: Flow Cytometry
Storage: 2-8Ā°C protected from light. Do not freeze
Formulation: Phosphate-buffered saline, pH 7.2, containing 0.1% PEG 3350, 0.1% Pluronic F-68, 0.05% Tween-20, 0.09% sodium azide and 1% BSA (BSA Country of Origin USA)
RECOMMENDED USAGE
Each lot of this antibody is quality control tested using flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 Ī¼L per 1 million cells in a staining volume of 100 Ī¼L. If whole blood is analyzed, then use 5 Ī¼L per 100 Ī¼L. It is recommended that users titrate the antibody to obtain the optimal result for their specific application.
Please briefly centrifuge the reagent vial before use.
Use appropriate personal protective equipment per the product safety data sheet when using this product.
