Abstract: A method and device for forming a cigarette filter rod. The method is as follows: in a process of continuously conveying forward cigarette filter materials that tend to converge to have a rod shape, multiple granular additives are continuously output in accordance with a certain time interval, and are sprayed into the cigarette filter materials that converge forwards under the action of continuous transporting flows, so that after the cigarette filter materials converge to form a continuous filter rod, multiple groups of additive unit combinations formed of different granular additive units are embedded in an axial direction of the filter rod.

Abstract: Fusion proteins that fluoresce and bind DNA, as well as nucleic acid constructs encoding the same are described herein. These imaging agents function in live cells to bind DNA and are thus useful for visualizing nuclei and chromosomes to make observations of nuclear and chromosomal structure and dynamics. The imaging agents may be used in screening assays to test the activity of biological effector molecules.
