Semaphorin-4D, also known as CD100, serves as a critical signaling molecule at the intersection of neuroscience and immunology research. Originally identified for its role in axonal guidance during neural development, SEMA4D has emerged as an important immunoregulatory protein that influences T cell activation, B cell responses, and dendritic cell function. Its involvement in neuroinflammatory processes and tumor microenvironment modulation has made it an increasingly valuable target for researchers investigating immune-neural crosstalk and disease mechanisms.
This recombinant monoclonal antibody, clone 21E8, offers the reproducibility and consistency that demanding experimental workflows require. Produced using recombinant technology with a defined sequence, this antibody eliminates the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations. The human IgG4 isotype with the S228P stabilizing mutation provides enhanced stability while minimizing Fc-mediated effector functions, making it particularly suitable for functional studies where background interference must be controlled.
Validation data demonstrates robust performance across complementary platforms. Flow cytometry analysis using transfected HEK293T cells stably expressing human SEMA4D confirms specific surface detection, with clear separation from untransfected controls at working dilutions of 1:50 to 1:200. Functional ELISA testing reveals strong binding affinity to human SEMA4D with EC50 values in the low nanogram range, while cross-species reactivity with mouse Sema4d has been confirmed, expanding utility for translational studies using murine models.
Supplied in a glycerol-based PBS buffer optimized for long-term storage stability, this antibody supports researchers investigating semaphorin biology across neurodevelopmental disorders, autoimmune conditions, and cancer immunology applications.
