Abstract: An in vivo method of modifying a genome of a target cell in a mammalian subject is described. The method includes administering an effective amount of a transducer cell to the subject, where the transducer cell includes a regulated viral vector delivery system (RVVDS) for producing and releasing viral transduction particles (VTPs) when the transducer cell is exposed to inducing conditions, and each VTP comprises a nucleic acid encoding a genome modification system (GMS) comprising a genome modification protein and one or more elements that regulate expression or activity of the genome modification protein in a mammalian cell.

Abstract: Methods for gene editing and predicting non-random editing events are described. The methods use Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) systems to characterize and manipulate DNA repair outcomes at Cas-initiated double-strand breaks (DSBs) to anticipate functional outcomes.

Abstract: Methods for preparing DNA libraries for protein engineering are described. The methods use programmable nucleases, such as from Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) systems, to generate diverse protein engineering libraries.

Abstract: Methods for use with Type II CRISPR-Cas9 systems for increasing Cas9-mediated genome engineering efficiency are disclosed. The methods can be used to decrease the number of off-target nucleic acid double-stranded breaks and/or to enhance homology-directed repair of a cleaved target nucleic acid.

Abstract: Disclosed are methods for analyzing molecular binding events in which the formation of ligand/antiligand complexes can be directly detected in a mixture without requiring separation of the components of the mixture from each other by measuring bulk properties of the mixture (i.e., properties that have contributions from several or all of the components present in the mixture). Using these techniques, it is possible to screen libraries without labeling either the target antiligand or ligand. The invention also provides a method for determining the strength of ligand/antiligand binding by further analysis of the same signals.
