Agarose gel electrophoretic evidence for domains of nuclear DNA linked with bonds cleavable with sulfhydryl molecules.

abstract：:Proteases not only play a fundamental role in numerous physiological processes, but are also involved in several human diseases including Alzheimer's disease (AD). A key protease implicated in AD is the so far unidentified gamma-secretase, which cleaves the membrane-bound beta-amyloid precursor protein (betaAPP) at th...
