Purpose

Ready-to-use AAV8 particles produced from pAAV-hSyn Con/Fon hChR2(H134R)-EYFP (#55645). In addition to the viral particles, you will also receive purified pAAV-hSyn Con/Fon hChR2(H134R)-EYFP plasmid DNA.

Synapsin-driven, Cre-dependent and Flp-dependent Channelrhodopsin-EYFP expression for optogenetic activation. These AAV preparations are suitable purity for injection into animals.

Delivery

  • Volume 100 µL
  • Titer ≥ 1×10¹³ 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, AAV8 cap gene
  • Buffer PBS + 0.001% Pluronic F-68
  • Serotype AAV8
  • Purification Iodixanol gradient ultracentrifugation
  • Reporter Gene EYFP

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

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

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 0.01-0.03% of viral vectors in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo. To address this, we recommend titrating to find the optimal AAV dosage required for Cre-dependent transgene expression and function in vivo. This may include reducing the viral vector dosage in order to reduce the likelihood of Cre-independent expression.

Information for AAV Retrograde (Catalog # 55645-AAVrg) ( Back to top )

Purpose

Ready-to-use AAV Retrograde particles produced from pAAV-hSyn Con/Fon hChR2(H134R)-EYFP (#55645). In addition to the viral particles, you will also receive purified pAAV-hSyn Con/Fon hChR2(H134R)-EYFP plasmid DNA.

Synapsin-driven, Cre-dependent and Flp-dependent Channelrhodopsin-EYFP expression for optogenetic activation. 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.

Delivery

  • 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 from rAAV2-retro helper (plasmid #81070)
  • Buffer PBS + 0.001% Pluronic F-68 + 200 mM NaCl
  • Serotype AAV retrograde (AAVrg)
  • Purification Iodixanol gradient ultracentrifugation
  • Reporter Gene EYFP

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 0.01-0.03% of viral vectors in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo.
