<ANSWER>[single letter: a, b, c, d, or e]</ANSWER>","I've been working with a CRISPRed population of mouse embryonic stem cells using a pair of gRNAs. When I run a PCR with primers flanking the target locus, I can see that deletions are happening. However, after cloning single cells, I only find the wild type band. Shouldn't I be seeing at least one heterozygous deletion? How many colonies should I typically check to find a homozygous deletion? What are your thoughts based on your experiences?",Checking a single colony is usually sufficient as CRISPR is highly efficient.,You should check 10-20 colonies to increase the chance of finding a heterozygous deletion since large deletions might destabilize the cells.,"The process is random, so any number of colonies will yield the same result.","You should check 50-100 colonies because large deletions may reduce the stability of edited cells, leading to fewer detectable deletions after cloning.",It is unusual to see only wild type bands; you should repeat your initial PCR to confirm the deletion.,d,Biology,medium,Advance Reasoning,Gene editing,Genome-Bench

These deletions vary, with some sequences having an AA deletion and others an AT deletion.
