Depositor Comments
The FlaviA-mNeptune reporter is not suitable for transient transfection as the reporter has a basal background that makes it sensitive to the levels of expression: If the expression is too high the background will mask the signal produced by the reporter and/or generate OSER structures - If the expression is too low you won’t detect enough signal over the background. Our recommendation is to use the pLenti-CMV-FlaviA-mNeptune-puro construct to pack lentiviral particles with the psPAX2 (Addgene #12260) and pMD2.G (Addgene #12259) plasmids, generate stable cell lines and sort cell subpopulations with different levels of the reporter's basal background before testing them. The best reporter cells will be those with the highest signal-to-noise ratio upon flavivirus infection.
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.
