    摘要: A method of site specific labelling of an interferon molecule is provided. The method comprises the steps: a) providing a label molecule comprising a PEG moiety having an aldehyde or ketone moiety; b) providing an interferon molecule having a C terminal hydrazide moiety; and c) allowing the aldehyde or ketone moiety of the PEG moiety to react with the C terminal hydrazide of the interferon molecule to form a labelled interferon molecule, which comprises a PEG moiety attached to the C terminus of the interferon molecule via a hydrazone bond. Interferon molecules labelled using such a method are also described.

    摘要: An apparatus for clearing tubing includes a grip assembly connected to the pair of rollers. The grip assembly is operable to move the rollers to engage the tubing therebetween. The movement of the grip assembly is limited such that a minimum tubing gap between the rollers is equal to approximately twice a wall thickness of the tubing. The rollers are moved along the tubing to clear obstructions. The apparatus can also include a clamp assembly having one or more plates that limits movement of the grip assembly to bring the rollers no closer than the minimum tubing gap. Alternately, the grip assembly can include first and second shell halves movable between open and closed positions with a channel defined therebetween, and the rollers are mounted in the grip assembly.
