Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Protocols
Specificity / Sensitivity
Presenilin 2 Antibody detects endogenous levels of the carboxy-terminal fragment of presenilin 2 (23 kDa) and the full length protein (54 kDa) to a lesser extent. It does not cross-react with endogenous levels of presenilin 1.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding amino acid 330 of human presenilin 2. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from human (293 and HeLa), mouse (NIH/3T3 and L929) and rat (C6 and PC12) cell lines, using Presenilin 2 Antibody.
Background
Presenilin 1 and presenilin 2 are transmembrane proteins belonging to the presenilin family. Mutation of presenilin genes has been linked to early onset of Alzheimer disease, probably due to presenilin's associated γ-secretase activity for amyloid-β protein processing (1,2). Endogenous presenilin mainly exists in a heterodimeric complex formed from the endoproteolytically processed amino-terminal (34 kDa) and carboxy-terminal (~20, 22, 23 kDa) fragments (CTF) (2,3).
