Addgene Comments
Using FLEX vectors in vivo: LoxP sites in FLEX plasmids are known to recombine during DNA amplification and viral vector production, which may result in a minority of Cre-activated (i.e., "flipped") viral vectors. Addgene has measured this occurs in 0.1-0.8% of viral particles in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo. To address this, it is necessary to optimize the injection volume and viral titer to find the optimal AAV dosage required for Cre-dependent transgene expression and function in vivo. This may include reducing the viral particle dosage in order to reduce the likelihood of Cre-independent expression.

Addgene Comments
Retrograde functionality is dependent on high viral titers. Addgene recommends not diluting your AAV preps prior to use.Using FLEX vectors in vivo: LoxP sites in FLEX plasmids are known to recombine during DNA amplification and viral vector production, which may result in a minority of Cre-activated (i.e., "flipped") viral vectors. Addgene has measured this occurs in 0.1-0.8% of viral particles in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo. To address this, it is necessary to optimize the injection volume and viral titer to find the optimal AAV dosage required for Cre-dependent transgene expression and function in vivo.
