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.
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.

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.
