Depositor Comments

The Singer Lab no longer recommends this plasmid, as it has a higher rate of bacterial recombination.

For mammalian cells they recommend the following plasmids:
pUbC-FLAG-24xSuntagV4-oxEBFP-AID-baUTR1-24xMS2V5-Wpre (Plasmid #84561)
HaloTag-bActinCDS-bActinUTR-MS2V5 (Plasmid #102718)

For yeast cells they recommend the following plasmids:
pET246-pUC57 12xMS2V6 (Plasmid #104390)
pET259-pUC57 24xMS2V6 (Plasmid #104391)
pET251-pUC 12xMS2V6 Loxp KANr Loxp (Plasmid #104392)
pET264-pUC 24xMS2V6 Loxp KANr Loxp (Plasmid #104393)

Due to the propensity of the plasmid to recombine, Addgene recommends screening multiple colonies by restriction analysis to ensure that the isolated clones contain a full set of 24 MS2 repeats
