Abstract: The present invention provides materials and methods for the utilization of the specific interaction of replication termination sequences with their binding proteins in molecular biology applications.

Abstract: The present invention relates generally to methods, kits and compositions for use in manipulating nucleic acid molecules, particularly cloning, sequencing, amplifying and mutating such molecules. In particular, the invention relates to use of recombination sites and recombinational cloning to manipulate, select and analyze nucleic acid molecules of interest.

Abstract: The invention provides a microarray and methods for producing a protein microarray. The array comprises multiple nucleic acid molecules immobilized on a substrate, each comprising (i) a protein-binding domain and (ii) a nucleic acid sequence encoding a fusion protein comprising a polypeptide of interest and a DNA-binding protein that binds the protein-binding domain, and one or more fusion proteins produced from the multiple nucleic acid molecules. Each fusion protein is immobilized on the substrate via binding to a nucleic acid sequence comprising the protein-binding domain present on the nucleic acid molecule from which the fusion protein is produced or on the substrate. The invention also provides a method of analyzing protein interactions with, for example, other proteins, lipids and drugs.

Abstract: The invention relates to a nucleic acid marker ladder which is a restriction endonuclease digest, wherein a nucleic acid restriction endonuclease digest is a collection of nucleic acid fragments resulting from complete digestion of one or more nucleic acids by one or more restriction endonucleases; the restriction endonuclease digest contains at least 3 fragments; and the size of the fragments in base pairs is a multiple of an integer, wherein the integer is 10 or more.

Abstract: Recombinational cloning is provided by the use of nucleic acids, vectors and methods, in vitro and in vivo, for moving or exchanging segments of DNA molecules using engineered recombination sites and recombination proteins to provide chimeric DNA molecules that have the desired characteristic(s) and/or DNA segment(s).

Abstract: The present invention provides nucleic acid molecules which may be used as standards for estimating the size (in base pairs) and mass of linear, double-stranded or single-stranded nucleic acid molecules separated by size. The nucleic acid molecules of the invention may be DNA molecules, RNA molecules or DNA/RNA hybrid molecules, and maybe double-stranded or single-stranded. The invention also provides methods for producing nucleic acid sizing ladders from these nucleic acid molecules, ladders produced by such methods, and methods for estimating the size and mass of nucleic acid molecules by comparison to these nucleic acid sizing ladders.
