Abstract: One aspect of the present invention describes materials and methods of quantitatively measuring the density or percent occupancy of DNA binding proteins such as histones, histone variants, histone post translational modifications and transcription factors in chromatin at given DNA loci. One embodiment measures a factor's average quantity at specific gene loci, and controls for a number of pitfalls concerning antibody quality and handling issues. Other embodiments include calibrating and quantifying chromatin immunoprecipitation assays, assessing an affinity reagent specificity, as well as required reagents and their formulation in kits. Another embodiment allows for the diagnosis of a condition or disease by measuring the density of a histone modification at a genomic locus.

Abstract: The invention relates to a method for screening a library of peptide ligands, said library comprising a plurality of polypeptides covalently linked to a molecular scaffold at two or more amino acid residues, comprising the steps of displaying said library of peptide ligands in a genetic display system, wherein the polypeptide comprises two or more reactive groups which form a covalent linkage to the molecular scaffold, and at least one loop which comprises a sequence of amino acids subtended between two of said reactive groups; exposing the peptide ligands to one or more cells which display one or more target molecules on the cell surface; and screening the peptide ligands for binding against the target, and selecting the ligands which bind to the target.

Abstract: An example of an array includes a support, a cross-linked epoxy polyhedral oligomeric silsesquioxane (POSS) resin film on a surface of the support, and a patterned hydrophobic polymer layer on the cross-linked epoxy POSS resin film. The patterned hydrophobic polymer layer defines exposed discrete areas of the cross-linked epoxy POSS resin film, and a polymer coating is attached to the exposed discrete areas. Another example of an array includes a support, a modified epoxy POSS resin film on a surface of the support, and a patterned hydrophobic polymer layer on the modified epoxy POSS resin film. The modified epoxy POSS resin film includes a polymer growth initiation site, and the patterned hydrophobic polymer layer defines exposed discrete areas of the modified epoxy POSS resin film. A polymer brush is attached to the polymer growth initiation site in the exposed discrete areas.
Abstract: The present invention relates to genomic analysis. In particular, the present invention provides methods and compositions for mapping genomic interactions.
Abstract: The invention provides a method for predicting whether a binding peptide, which binds to a target peptide presented by a Major Histocompatibility Complex (MHC) and is for administration to a subject, has the potential to cross react with another peptide in the subject in vivo. The method comprises the steps of identifying at least one binding motif in the target peptide to which the binding peptide binds; and searching for peptides that are present in the subject that comprise the at least one binding motif and that are not the target peptide. The presence of one or more such peptides indicates that the binding peptide has the potential to cross react in vivo.
Abstract: Provided is a pig genome-wide specific sgRNA library, a preparation method therefor, and an application thereof. The sgRNA is targeted at a pig genome-wide protein-coding gene, lincRNA and/or miRNA. Specifically, an sgRNA construct has the following structure: AL-N20-AR, wherein AL is the left homology arm sequence located at the upstream of the coding sequence of a pig specific SgRNA, N20 is the coding sequence of the pig specific SgRNA, and AR is a right homology arm sequence located at the downstream of the coding sequence of the pig specific sgRNA. The sgRNA library can be used for screening functional genes of a pig or for preparing a kit.

Abstract: Fiducial markers are provided on patterned arrays of the type that may be used for molecular analysis, such as sequencing. The fiducials may have configurations that enhance their detection in image or detection data, that facilitate or improve processing, that provide encoding of useful information, and so forth. Examples of the fiducials may include an “always on” type that respond to multiple frequencies of radiation used during processing and detection so as to return signals during successive cycles of imaging.
