WebTo compare the responses of the Q-beads to those of the conventional Q-body, we generated Q-bodies as follows: 25 μL of anti-FLAG M2 monoclonal antibody beads were added to the eluent after His-tag purification and incubated at 25 °C. After 1 h, the beads were washed three times with 1 mL of PBS. WebOne promising application of the CRISPR/Cas9 system is for tagging genes with a fluorescence marker or tag peptides. For such a purpose, FLAG, HIS, and HA tags or fluorescence proteins (EGFP, BFP, RFP, etc.) have been broadly used to tag endogenous genes of interest.
