  • Publication number: 20240102079
    Abstract: In some embodiments, the disclosure relates generally to compositions, comprising a single reaction mixture containing a plurality of different populations of discrete supports, and a plurality of different populations of target nucleic acids. The single reaction mixture can contain a first population of beads; a second population of beads; a first population of target nucleic acids, where at least two different target nucleic acids in the first population of target nucleic acids can bind to a bead in the first population of beads; and a second population of target nucleic acids, where at least two different target nucleic acids in the second population of target nucleic acids can bind to a bead in the second population of beads. The single reaction mixture can be employed to monoclonally amplify the first target nucleic acids on the first beads, and monoclonally amplify the second target nucleic acids on the second beads.

  • Publication number: 20080161206
    Abstract: Biopolymeric array scanners that are capable of automatically selecting a dye specific scale factor to employ for a plurality of different dyes, as wells as methods for making and using the same, are provided. In many embodiments, the actual dye specific scale factor automatically selected by the scanner is one that is equal to a preset “master” scale factor, so that the scanner reads any supported dye using the same constant scale factor. The dye specific scale factor selection is typically made by reference to a collection of nominal scale factors for each member of the plurality of dyes. In using the subject scanners, a user simply inputs the one or more dyes being used in a given array assay, and the scanner automatically reads the array using an automatically chosen dye specific scale factor for the selected dyes. Also provided are methods of obtaining collections of nominal scale factors and computer readable mediums comprising the same.
