There is a small discrepancy between the reference sequence and Addgene's quality control sequence, this causes an A to G mutation in the linker region between NLS and ddRFP B. This change should not affect plasmid function.
These plasmids were created by your colleagues. Please acknowledge the Principal Investigator, cite the article in which the plasmids were described, and include Addgene in the Materials and Methods of your future publications.
