摘要: Compositions, methods and a kit are described relating to a novel family of enzymes which preferentially bind to a hydroxymethylated cytosine or a glucosylated hydroxymethylated cytosine and cleave double-stranded DNA at a defined distance 3′ of the recognition site to produce a cleavage fragment with a 1-3 base overhang.

摘要: Disclosed is a device for angling a multi-well plate during shaking on a typical low speed laboratory incubator-shaker to facilitate cell growth. An assembly with a holder for a deep-well multi-well plate to attach it to a base has an adjustable-angle joint. The base is attached to a conventional incubator shaker tray via screws or a sticky pad. The adjustable-angle joint allows maintaining the desired angle of the plate, even at full shaking speed.
