Western Blot Detection of Mouse Semaphorin 4G antibody by Western Blot. View Larger

Detection of Mouse Semaphorin 4G by Western Blot. Western blot shows lysates of mouse brain (cortex) tissue. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Mouse Semaphorin 4G Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6504) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Semaphorin 4G at approximately 110 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1

Semaphorin 4G in Mouse Embryo. Semaphorin 4G was detected in immersion fixed frozen sections of mouse embryo (15 d.p.c.) using Sheep Anti-Mouse Semaphorin 4G Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6504) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counter-stained with hematoxylin (blue). Specific staining was localized to developing brain (cortex) and connective tissue. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: Semaphorin 4G

Semaphorin 4G (Sema4G) is a 92 kDa (predicted), class IV member of the semaphorin family of proteins. It is expressed by select cell types, including oligodendroglia and Purkinje neurons, and likely acts as a chemorepellent by binding to B-type plexins. Mature mouse Sema4G is a type I transmembrane protein that is 820 amino acids (aa) in length. It contains a 656 aa extracellular region (aa 18-673) that is characterized by one Sema domain (aa 35-503), a PSI region (aa 505‑556), and an Ig-like C2-type domain (aa 565-648). The 143 aa cytoplasmic region contains a poly-proline segment and a Ser phosphorylation site. Over aa 18‑673, mouse Sema4G shares 91% and 97% aa identity with human and rat Sema4G, respectively.
