CD19 serves as a critical B lymphocyte surface marker that plays an essential role in regulating B cell development, activation, and differentiation. As a component of the B cell receptor signaling complex, CD19 amplifies immune responses and has become a cornerstone target in immunology research, particularly in studies of B cell malignancies, immunodeficiencies, and the development of CAR-T cell therapies.
This recombinant monoclonal antibody, clone 27G9, offers researchers the consistency and reliability that comes with sequence-defined production. Unlike traditional hybridoma-derived antibodies, recombinant technology ensures that every lot performs identically to the last, eliminating the variability that can compromise longitudinal studies or require repeated optimization. The antibody was raised against recombinant human CD19 protein and has been validated for human sample detection.
Western blot validation demonstrates clean, specific detection at the expected 62 kDa molecular weight in both Raji and Jurkat whole cell lysates, confirming reliable performance across different B cell and T cell leukemia models. The recommended working dilution of 1:500 to 1:2000 provides flexibility to optimize signal intensity based on your specific experimental conditions and sample abundance. Additional validation for ELISA applications extends the utility of this antibody across different experimental workflows.
Affinity-purified to ensure high specificity and supplied in a glycerol-based buffer for long-term stability, this CD19 antibody supports researchers investigating B cell biology, hematological malignancies, stem cell differentiation, and immune system development. Whether characterizing patient samples or validating cell line models, this antibody delivers the reproducible performance essential for meaningful experimental outcomes.
