Array Assembler Provides Greatly Simplified crRNA Array Design for CRISPR Cas12 and Cas13 Variants.

As newer CRISPR variants have emerged and corresponding toolkits have been developed, researchers can now readily target multiple genes simultaneously for knockout, activation, or repression alongside being able to bind or cleave mRNA. However, as larger multitargeting crRNA arrays are required for these experiments, the design process becomes more complicated, taking more time and increasing risks of errors being introduced. The Array Assembler seeks to address the critical bottleneck that emerges during longer crRNA array design by providing a highly user-friendly tool to process input crRNA spacer sequences into the oligos required for efficient assembly of the corresponding crRNA array. By enabling rapid and reliable design of oligos for efficient assembly of crRNA arrays from a user-defined list of crRNA spacer sequences this tool should prove useful for a wide range of laboratories employing genomic perturbations.
