Detection of Human Galanin by Western Blot. Western blot shows lysates of SH‑SY5Y human neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Galanin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5854) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Galanin at approximately 10 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of Human Galanin by Simple WesternTM. Simple Western lane view shows lysates of SH‑SY5Y human neuroblastoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Galanin at approximately 13 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human Galanin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5854) 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.

Galanin (Glycine-Alanine, representing the N-and C-terminal amino acids in bovine Galanin; also GAL) is a 3 kDa (predicted), secreted member of the Galanin family of peptides. It is co-expressed with differing neuropeptides in a variety of neuron cell types. Galanin affects multiple metabolic processes by binding to one of three GPCRs. GalR1 blocks insulin secretion, GalR2 initiates neurogenesis and GalR3 influences addictive behavior. The human Galanin proform is 10‑12 kDa in size (predicted) and 104 amino acids (aa) in length. Proteolytic processing generates a 30 aa mature Galanin peptide (aa 33‑62), plus a phosphorylated (Ser117), C-terminal 59 aa GMAP fragment that is apparently involved in the processing of noxious stimuli. Once secreted, Galanin can undergo additional proteolytic degradation. Over aa 20‑123, the human Galanin proform shares 72% aa identity with mouse Galanin proform.
