Resource Information

Depositor Comments

The addition of the P2A-nls-dTomato allows for easy identification of GCaMP6 expressing cells exhibiting nuclear red fluorescence that does not significantly overlap with the cytosolic GCaMP signal. The GCaMP and fluorophore are physically uncoupled.

Permissions were obtained from Douglas Kim and the Clontech licensing office for depositing this new plasmid.

Purpose

Ready-to-use AAV Retrograde particles produced from AAV-EF1a-DIO-GCaMP6f-P2A-nls-dTomato (#51083). In addition to the viral particles, you will also receive purified AAV-EF1a-DIO-GCaMP6f-P2A-nls-dTomato plasmid DNA.

Cre-dependent GCaMP6f calcium sensor and physically separate nuclear tdTomato, under control of the EF1a promoter. 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.

Biosafety

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.
Notes:
  • 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 that only produce amplicons in the DIO orientation. PCR was also carried out on the viral preparation with primers targeting the transgene. The PCR products were visualized on an agarose gel for size confirmation.

Addgene Comments

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