Presenilin 2
Description:
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’s disease, probably functioning through its associated gamma-secretase activity for amyloid-beta protein processing (1,2). Endogenous presenilin mainly exists in a heterodimeric complex formed from the endoproteolytically processed N-terminal (34kD) and C-terminal (~20kD) fragments (2,3).

Applications:
Suitable for use in Western Blot and Immunoprecipitation. Other applications have not been tested.

Recommended Dilutions:
Western Blot: 1:1000
Immunoprecipitation: 1:50
Optimal dilutions to be determined by the researcher.

Positive Control:
293 and HeLa (human), NIH/3T3 and L929 (mouse), and C6 and PC12 (rat) cell lines

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
