Aptamer-functionalized stir bar sorptive extraction coupled with gas chromatography-mass spectrometry for selective enrichment and determination of polychlorinated biphenyls in fish samples.
Ningbo, China. In Talanta, Apr 2016
This approach was based on the immobilization of aptamer which could recognize 2,3',5,5'-tetrachlorobiphenyl (PCB72) and 2',3',4',5,5'-pentachlorobiphenyl (PCB106) on one kind of metal-organic frameworks (Zn4O(BDC)3, MOF-5).
Chromatin and pluripotency: the MYSTerious connection.
New Haven, United States. In Cell Stem Cell, 2012
(2012) now show that Mof, a MYST family histone acetyltransferase, functions as a coactivator of Nanog-mediated transcription, maintains the expression of pluripotency-associated genes, and primes developmental genes for differentiation.
