Disease Detection in Liquid Biopsies
Described are methods of analyzing cell free DNA based on combining analysis of cfDNA methylation with analysis of the cfDNA nucleosome footprint and/or with analysis of cfDNA copy number alteration. The diagnostic performance of these methods, in particular relating to early or earlier stage diseases or disorders, is increased compared to the diagnostic performance of the individual cfDNA analysis methods.

Pooled Crispr Inverse PCR Sequencing (PCIP-Seq): Simultaneous Sequencing of Viral Insertion Points and the Integrated Viral Genomes with Long Reads
The present invention relates to a method for detecting an integration pattern of a virus in a host genome. In particular, a method is provided encompassing selective cleavage of circularized DNA fragments carrying viral DNA with an RNA-guided endonuclease and at least one guide RNA or at least one pool of guide RNAs, followed by inverse PCR, in particular inverse long-range PCR, and sequencing. The invention further relates to kits for performing the method and application of the method.

METHODS OF DETERMINING VIRAL TITER
The present disclosure relates to methods for determining a viral titer of a biological sample, suitably from a mammalian cell sample. The methods include the use of mechanical disruption of the cells, followed by droplet digital polymerase chain reaction (ddPCR) to determine the viral titer. Methods of mechanical disruption suitably include the use of glass beads.
DEVICES AND METHODS FOR DETERMINING NUCLEIC ACIDS USING DIGITAL DROPLET PCR AND RELATED TECHNIQUES
The present disclosure generally relates, in certain aspects, to droplet-based microfluidic devices and methods. In certain aspects, target nucleic acids contained within droplets are amplified within droplets in a first step, where multiple primers may be present. However, multiple primers may cause multiple target nucleic acids to be amplified within the droplets, which can make it difficult to identify which nucleic acids were amplified. In a second step, the amplified nucleic acids may be determined. For example, the droplets may be broken and the amplified nucleic acids can be pooled together and sequenced. As an example, new droplets may be formed containing the amplified nucleic acids, and those nucleic acids within the droplets amplified by exposure to certain primers.
