About Presenilin-2
Alzheimer's disease (AD) patients with an inherited form of the disease carry mutations in the presenilin proteins (PSEN1 or PSEN2) or the amyloid precursor protein (APP). These disease-linked mutations result in increased production of the longer form of amyloid-beta (main component of amyloid deposits found in AD brains). Presenilins are postulated to regulate APP processing through their effects on gamma-secretase, an enzyme that cleaves APP. Also, it is thought that the presenilins are involved in the cleavage of the Notch receptor such that, they either directly regulate gamma-secretase activity, or themselves act are protease enzymes. Two alternatively spliced transcript variants encoding different isoforms of PSEN2 have been identified. [provided by RefSeq, Jul 2008]

About DyLight 350
DyLight™ 350 has an excitation peak of 353 nm and an emission peak of 432 nm. It is spectrally similar to Alexa Fluor™ 350, iFluor® 350, AMCA, and Thioflavin T. DyLight™ 350 is most commonly used in flow cytometery and fluorescence microscopy applications.
