Scientific Data Images for Human Semaphorin 4B Antibody

Detection of Human Semaphorin 4B antibody by Western Blot.

Detection of Human Semaphorin 4B by Western Blot.

Western blot shows lysates of human brain tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Semaphorin 4B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5485) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Semaphorin 4B at approximately 96 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: Semaphorin 4B

Semaphorin 4B (Sema4B; also SemaC) is a 95‑100 kDa, class IV member of the Semaphorin family of proteins. It is expressed in neurons, and following PSD-95 induced clustering, participates in the formation or functioning of glutamatergic synapses. Mature human Sema4B is a type I transmembrane glycoprotein that is 794 amino acids (aa) in length. It contains a 674 aa extracellular region (aa 39‑832) that is characterized by one Sema domain (aa 65‑502), a PSI region (aa 520‑574), and an Ig-like C2-type domain (aa 599‑658). There is one potential soluble splice variant that shows a 29 aa substitution for aa 707‑832. Over aa 39‑712, human Sema4B shares 86% aa identity with mouse Sema4B.
