    Abstract: The disclosure provides methods for the concurrent assessment of large numbers of genome engineering proteins, including CRISPR nucleases and base editors. Specifically, the disclosure provides methods of providing a plurality of individual discrete samples comprising populations of cells, wherein each population of cells overexpresses both (i) a single genome engineering protein or a variant thereof and (ii) a reporter protein, lysing the cells to release the proteins; normalizing levels of the genome engineering proteins or variants thereof; allowing the genome engineering proteins or variants thereof to combine with a guide RNA under conditions sufficient to form ribonucleoprotein complexes in each sample; contacting each sample with a plurality of analysis substrates, determining levels of each of the analysis substrate in each sample at a plurality of times; and calculating rate of depletion or enrichment of each of the analysis substrates from each sample.
