Hi Marc!
Thank you for your question! I really apologize that there has been such a delay in answering directly. I recommend referencing our cell line catalog (Cell Catalog - Allen Cell Explorer) for crRNA or gRNA sequences, details about our cell line generation process, cell culture methods, and other tips for assessing genomic integrity after editing your cells-- we try to make as much of these things open and available to researchers like yourself as possible.
Other users have asked similar questions, so you may find additional tips by perusing other discussion threads such as this one: Plasmids for my lab?
Let me know if this answers your question or if I can help in some other way!
Maggie
