MA1-752 detects presenilin 1 protein (PS1) from mouse, rat, human, and nonhuman primate samples. No cross-reactivity is seen with presenilin 2.
MA1-752 has successfully been used in immuno-fluorescence, immunocytochemistry, Western blot, immunoprecipitation, and ELISA procedures. By Western blot, this antibody detects an ~18 kDa protein representing PS1 CT (C-terminus fragment) and the ~46 kDa full-length PS1 from transfected SH-SY5Y cells. In 4% paraformaldehyde fixed N2a cells, MA1-752 showed endogenous PS1 staining in the Golgi and cellular vesicles.
The MA1-752 immunogen is a synthetic peptide corresponding to residues C S(313) K Y N A E S T E R E S Q D T V A E N D D G(334) of humen PS1.
Familial Alzheimer's disease is often characterized by an early (<60 years of age) and rapid deterioration of the central nervous system. The symptoms are caused by the abnormal buildup of senile plaques composed of the 42 residue amyloid-beta peptide. This peptide is the result of the amyloid precursor protein being cleaved by the presenilin-gamma-secretase complex. Recent studies have linked mutations in presenilin 1 (PS1) and presenilin 2 (PS2) to a rapid increase in plaque accumulation.
PS1 and PS2 are integral membrane proteins that contain 6-8 transmembrane domains and are predominantly localized within the endoplasmic reticulum and Golgi of neurons within the brain. Within the transmembrane regions of PS1 and PS2 there is over 60% homology, with the largest divergence found at the N-terminus and large loop region.
