Abstract: The invention relates to methods for capturing a polynucleotide comprising a DNA target segment from a population of polynucleotide molecules. The method may use a mixture comprising the population of the polynucleotide molecules, one or more polynucleotide primers, nucleotides, biotinylated nucleotides, a polymerase enzyme and a buffered liquid medium. The method may denature the polynucleotide molecules in the mixture so as to create single stranded portions of the polynucleotide molecules which can be accessible to the polynucleotide primers; hybridizing the polynucleotide primers to the polynucleotide comprising the DNA target segment. The method may create an extended polynucleotide primer by using the nucleotides, the biotinylated nucleotides and the polymerase enzyme as a means for labeling with biotin and increasing the extent of hybridization of the extended polynucleotide primer to the polynucleotide comprising the DNA target segment.

Abstract: The invention relates to methods for capturing a polynucleotide comprising a DNA target segment from a population of polynucleotide molecules using a rotation of a magnetic field to move streptavidin-labeled magnetic beads relative to a buffered liquid medium to increase the probability of capturing and preventing damage to a long polynucleotide comprising a DNA target segment. The methods may use a rotation of the magnetic field relative to the mixture or a rotation of the mixture relative to the magnetic field for causing magnetic bead rotation in the buffered liquid medium and increasing the binding of biotinylated nucleotides of an extended polynucleotide primer to streptavidin-labeled magnetic beads, and winding or condensation of a polynucleotide onto the streptavidin-labeled magnetic beads to prevent damage to the long polynucleotide comprising a DNA target segment.

Abstract: An automated protein preparation technology that may use magnetic microparticles to isolate proteins in their native state from specific genomic loci of interest via the chromatin to which they are bound is described. After extraction, the targeted proteins may be purified for downstream analysis by quantitative mass spectrometry or ELISA. The identification of DNA-bound proteins, histones and their post-translational modification is of high scientific and pharmaceutical importance due to the role of DNA-binding proteins in the cauzation and development of human disease; in particular, cancer.
