alpha-2,6-Sialyltransferase ELISA Kits

The accumulation of amyloid beta protein in the cerebral cortex in Alzheimer's disease (AD) is only one of the outcomes of proteolytic cleavage of amyloid precursor protein (APP). More than 50 different mutations in the APP gene can cause early-onset Alzheimer disease. Cleavage by beta- and gamma-secretase (amyloidogenic pathway) leads to production of amyloid-beta. Alpha-2,6-sialyltransferase (ST6Gal I) is a glycosyltransferase involved in the biosynthesis of sugar chains. It is also known as alpha 2,6-ST 1, CMP-N-acetylneuraminate-beta-galactosamide-alpha-2,6-sialyltransferase 1, sialyltransferase 1 (beta-galactoside alpha-2,6-sialyltransferase), ST6 beta-galactosamide alpha-2,6-sialyltranferase 1, ST6N, and SIAT1. Recent studies have shown that ST6Gal I is also cleaved by beta-secretase, both in vitro and in vivo, to produce a peptide known as ST6Gal I (E41 Form).

These kits are solid-phase sandwich ELISAs using two antibodies that are highly specific to human, mouse, and rat ST6Gal I protein (Cat.# 27762) and rat ST6Gal I (E41 form) (Cat.# 27408); one is precoated on the ELISA plate and the other is HRP-conjugated. These kits can be used to measure ST6Gal I in serum, EDTA plasma, or cell culture supernatant.
