Scientific Data

Western Blot Detection of Human PSAP antibody by Western Blot. View Larger

Detection of Human PSAP by Western Blot. Western blot shows lysates of A431 human epithelial carcinoma cell line. PVDF membrane was probed with 1:1000 dilution of Rabbit Anti-Human PSAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8520) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). Specific bands were detected for PSAP at approximately 60-80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunocytochemistry PSAP antibody in A431 Human Cell Line by Immunocytochemistry (ICC). View Larger

PSAP in A431 Human Cell Line. PSAP was detected in immersion fixed A431 human epithelial carcinoma cell line using Rabbit Anti-Human PSAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8520) at 1:100 dilution for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; Catalog # NL004) and counterstained with DAPI (blue). Specific staining was localized to Golgi.

Simple Western View Larger

Detection of Human PSAP by Simple WesternTM. Simple Western lane view shows lysates of A431 human epithelial carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for PSAP at approximately 98 kDa (as indicated) using 2 µg/mL of Rabbit Anti-Human PSAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8520). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: PSAP

Prosaposin behaves as a myelinotrophic and neurotrophic factor, whose effects are mediated by its G-protein-coupled receptors, GPR37 and GPR37L1, undergoing ligand-mediated internalization followed by ERK phosphorylation signaling.By similarity Saposins are specific low-molecular mass non-enzymic proteins and participate in the lysosomal degradation of sphingolipids, which takes place by the sequential action of specific hydrolases. The Prosaposin gets cleaved into 5 chains, Saposin A, B, B-Val, C and D. It also contains several disulfide bonds as well as glycosylation sites.
