Information for AAV Retrograde (Catalog # 104488-AAVrg) ( Back to top )


Ready-to-use AAV Retrograde particles produced from pGP-AAV-syn-jGCaMP7f-WPRE (#104488). In addition to the viral particles, you will also receive purified pGP-AAV-syn-jGCaMP7f-WPRE plasmid DNA.

Synapsin-driven GCaMP7f calcium sensor. These AAV were produced with a retrograde serotype, which permits retrograde access to projection neurons. These AAV preparations are suitable purity for injection into animals.


  • Volume 100 µL
  • Titer ≥ 7×10¹² vg/mL
  • Pricing $350 USD for preparation of 100 µL virus + $30 USD for plasmid.
  • Storage Store at -80℃. Thaw just before use and keep on ice.
  • Shipment Viral particles are shipped frozen on dry ice. Plasmid DNA (≥ 200ng) will also be included in the shipment.

Viral Production & Use

  • Packaging Plasmids encode adenoviral helper sequences and AAV rep gene, AAV retrograde cap gene
    rAAV2-retro helper (plasmid #81070)
  • Buffer PBS + 0.001% Pluronic F-68 + 200 mM NaCl
  • Serotype AAVrg rAAV2-retro helper (plasmid #81070)
  • Purification Iodixanol gradient ultracentrifugation


Requestor is responsible for compliance with their institution's biosafety regulations. Lentivirus is generally considered BSL-2. AAV is generally considered BSL-1, but may require BSL-2 handling depending on the insert. Biosafety Guide

Viral Quality Control

Titering Method:
  • Real-time qPCR: The number of genome copies in viral preparations was measured by SYBR green real-time qPCR with primers targeting the ITR. Titer values were deduced by comparing the genomic content of the viral preparation to a standard curve of a plasmid of known concentration. Read our AAV Titration by qPCR protocol here.
  • Purity of viral preparation: Viral preparations were subjected to polyacrylamide gel electrophoresis (PAGE) followed by silver staining and the molecular weight and relative intensity of the viral capsid proteins was analyzed. The abundance of viral capsid proteins as a fraction of total protein present in the sample was used to determine purity of the AAV preparation.
  • PCR confirmation of viral genome: PCR was carried out on the viral preparation with primers targeting the transgene. The PCR products were visualized on an agarose gel for size confirmation.
    • Transgene

Addgene Comments

Retrograde functionality is dependent on high viral titers. Addgene recommends not diluting your AAV preps prior to use.
