LiBHEt 3 deprotonates carboxylic acids, but does not reduce the resulting lithium carboxylates. For similar reasons, epoxides undergo ring-opening upon treatment with LiBHEt 3 to give the alcohol. With unsymmetrical epoxides, the reaction can proceed with high regio- and stereo- selectivity, favoring attack at the least hindered position:
H3K4me3 is a commonly used histone modification. H3K4me3 is one of the least abundant histone modifications; however, it is highly enriched at active promoters near transcription start sites (TSS) [9] and positively correlated with transcription.
9-round (9×19mm) or 7-round (.45 ACP) single column, detachable box magazine The HK P9 is a semi-automatic pistol from Heckler & Koch in 9×19mm Parabellum , .45 ACP , and 7.65×21mm Parabellum and the first to use a variation of H&K 's roller delayed blowback system in a pistol format and polygonal rifling [ 1 ] now common in H&K designs.
Whether intended or not, the obvious pun connection to Detective Joe Friday's badge number 714 from Dragnet drew many a smile and chuckle from older reserve augmentees newly assigned or detailed to the unit with some instantly saying or mouthing "Dragnet" on first learning the unit designation during The Surge phase in 2007–2008.
3. Assay for transposase accessible chromatin sequencing is used to look in to regions that are nucleosome free (open chromatin). It uses hyperactive Tn5 transposon to highlight nucleosome localisation. [13] [14] [15]

H3K36me3 is an epigenetic modification to the DNA packaging protein Histone H3.It is a mark that indicates the tri-methylation at the 36th lysine residue of the histone H3 protein and often associated with gene bodies.
