I am planning to tag a gene using CRISPR. The FLAG/Myc-tagged lines generally give high background in the germ line, so was planning to use OLLAS-tag. I was wondering if anyone has generated OLLAS-tagged transgenic or CRISPR’ed line! If yes, which antibody is used to detect it? How is the background?
Alexandre Paix mentions inserting Ollas tags by CRISPR in a couple of papers. I didn’t notice any staining in a quick glance at those papers, but you might contact him and ask what his experience has been.
