What is the optimal amount of Alt-R HDR Donor Blocks to use with my cell type and what can I do to prevent toxicity and/or cell death after delivering Alt-R HDR Donor Blocks?

Due to recognition of cytosolic dsDNA by innate immune response pathways, careful consideration of the final Alt-R™ HDR Donor Block concentration is necessary to avoid cytotoxicity.  We recommend testing for optimal concentrations for each cell line you use, as sensitivity to dsDNA may vary.  To learn more, go to the Alt-R Donor Blocks protocol.
