Data Examples

Western Blot Detection of Human Semaphorin 4D/CD100 antibody by Western Blot. View Larger

Detection of Human Semaphorin 4D/CD100 by Western Blot. Western blot shows lysates of IMR-32 human neuroblastoma cell line and Y-79 human retinoblastoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Semaphorin 4D/CD100 Monoclonal Antibody (Catalog # MAB74701) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Semaphorin 4D/CD100 at approximately 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Semaphorin 4D/CD100

Semaphorin 4D (Sema4D/CD100, previously sem J, G or C-like 2) is a widely expressed 150 kDa type I transmembrane glycoprotein of the Class 4 Semaphorin family with activity in the immune and nervous systems. The 861 amino acid (aa) Semaphorin 4D contains a 710 aa extracellular domain (ECD) with a sema domain and an immunoglobulin-like domain. Within the ECD region used as an immunogen, mouse Semaphorin 4D shares 87% and 93% aa identity with human and rat Semaphorin 4D, respectively. A soluble, active 120 kDa form is produced proteolytically upon activation of B and T cells. Semaphorin 4D binds CD72 on B and dendritic cells and Plexin B1 elsewhere. In developing neurons, Semaphorin 4D assists in guidance. Semaphorin 4D is proangiogenic when expressed by tumor‑associated macrophages.
