Presenilin‑1 in Human Brain.
Presenilin‑1 was detected in immersion fixed paraffin-embedded sections of human brain (medulla) using Mouse Anti-Human Presenilin‑1 N-Terminal Fragment Monoclonal Antibody (Catalog # MAB149) at 1.7 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cell bodies.

Presenilin‑1 (PS-1) is a multipass lysosomal membrane protein that is a component of the gamma secretase complex. It is cleaved by endoproteolysis to generate N‑ and C‑terminal fragments. Some mutations in PS-1 are associated with the risk of early onset familial Alzheimer's disease.
