Depositor Comments

Please note Addgene Quality Control sequence found mutation K278T in KLF4.

Oct4 and Sox2 are coexpressed under a strong EF promoter. SV40LT and Klf4 are coexpressed under a separate (but identical) EF promoter. This plasmid contains EBNA-1 and OriP for limited maintenance in mammalian cells.

These plasmids were used at concentrations of >1.5 mg/ml. When preparing these plasmids for transfection, 3 low concentration maxipreps are done and the elution is combined in about 700 ul.

Addgene recommends screening 3-5 colonies immediately upon receipt, as this plasmid may be prone to recombination.
