Viral Quality Control

Quality Control:
  • Addgene ensures high quality viral vectors by optimizing and standardizing production protocols and performing rigorous quality control (QC) (see a list of our QC assays). The specific QC assays performed varies for each viral lot. To learn which specific QC assays were performed on your lot, please contact us.
  • Titer: the exact titer of your sample will be reported on the tube. The titer you see listed on this page is the guaranteed minimum titer. See how titers are measured.

Visit our viral production page for more information.

Addgene Comments

Dr. Wickersham has tested this lot#v14715 (2.4 × 10^13 GC∕mL) and he recommends a 1:10 dilution.

When selecting what system to use, keep in mind that the sTpEptTA (Addgene#100798) + TRE (Addgene# 100799) combination allows reduction of background infection by Rabies Virus in wild-type mice to acceptably few cells while still allowing nice amounts of transsynaptic spread in Cre+ mice. Note that EGFP can be seen only with immunostaining at these dilutions. This vector (Addgene #52473) is simpler because you only need to inject a single AAV but forces a less optimal compromise: more background or less transsynaptic spread.

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.
