According to various embodiments, a method is provided that comprises washing an array of DNA-coated beads on a substrate, with a wash solution to remove stacked beads from the substrate. The wash solution can include inert solid beads in a carrier. The DNA-coated beads can have an average diameter and the solid beads in the wash solution can have an average diameter that is at least twice the diameter of the DNA-coated beads. The washing can form dislodged DNA-coated beads and a monolayer of DNA-coated beads. In some embodiments, first beads for forming an array are contacted with a poly(ethylene glycol) (PEG) solution comprising a PEG having a molecular weight of about 350 Da or less. In some embodiments, slides for forming bead arrays are provided as are systems for imaging the same.

Methods of bead manipulation and forming bead arrays

The present teachings relate, among other things, to polynucleotide sequencing, fragment analysis and sample/lane tracking, and to polynucleotide sequencers and analyzers that employ optical detection techniques. Embodiments of the present teachings are described which include, for example, the addition of a calibration standard to a sequencing reaction. Information such as peak spacing and peak shape can be extracted from the standard.

Internal calibration standards for electrophoretic analyses

This invention provides a duplex comprising an oligonucleotide primer and a template, wherein the primer is coupled chemically to a chromophore or fluorophore so as to allow chain extension by a polymerase. In one embodiment, the primer is extended by a polymerase to generate the complement of the template. In a further embodiment, the extended primer is separated from the template for use in a number of methods, including sequencing reactions. Methods of generating these compositions of matter are further provided.
