Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Human Semaphorin 4C by Western Blot. Western blot shows lysates of SW13 human adrenal cortex adenocarcinoma cell line. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human Semaphorin 4C Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6125) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Semaphorin 4C at approximately 110 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of Human Semaphorin 4C by Simple WesternTM. Simple Western lane view shows lysates of SW13 human adrenal cortex adenocarcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Semaphorin 4C at approximately 121 kDa (as indicated) using 25 µg/mL of Sheep Anti-Human Semaphorin 4C Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6125) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.
Semaphorin 4C in Human Brain. Semaphorin 4C was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using Sheep Anti-Human Semaphorin 4C Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6125) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cell bodies. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Semaphorin 4C
Sema4C (Semaphorin 4C; also Sema I and M-SemaF) is a 100-105 kDa, class IV member of the semaphorin family of proteins. It is expressed by precursors to neurons and myocytes, and may regulate their differentiation into mature forms. Mature human Sema4C is a type I transmembrane glycoprotein that is 813 amino acids (aa) in length. It contains a 643 aa extracellular region (aa 21-663) that is characterized by the presence of one Sema domain (aa 30-497), a PSI region (aa 499‑551), and an Ig-like C2-type domain (aa 556-644). The cytoplasmic region interacts with PZD-domain containing proteins. There are three potential splice variants. One demonstrates an alternative start site at Met324, a second shows a deletion of aa 173-211, and a third contains an 89 aa substitution for aa 1-36. Over aa 21‑663, human Sema4C shares 85% aa identity with mouse Sema4C.
