New and Upcoming Viral Vectors - June 2019

By Leila Haery

New Viral Vectors AddgeneSince the beginning of our viral service in 2016, we’ve added many new tools to our inventory of ready-to-use viral vectors. Here are some of the AAV we have released in the last few months. You can also browse our entire AAV inventory.

Our new AAVs include:

  • Control AAVs for serotype testing
  • jGCaMP7c for calcium detection
  • PSAM4 GlyR for chemogenetic inhibition
  • Flp expression for intersectional studies
  • And more!

Control AAV

We’re always excited to add new control AAVs to our inventory since we know that scientists need these tools both for pilot experiments and for interpreting the results of studies. When planning AAV experiments, scientists often have to choose the best serotype for their particular study, which includes comparing the transduction patterns of different AAV serotypes. To help make this easier for scientists, we now offer trial size 20 µL samples of control AAV that scientists can use for serotype testing. These samples are available in various serotypes of two popular control AAV encoding GFP.

50465 AAV8, 9 (20 µL size serotype testing) AAV-hSyn-EGFP

Biosensor AAV

The ability to detect the neurotransmitters and other bioactive molecules is integral to the study of neuroscience. To this end, new biosensing AAV are always being developed and we are excited to offer these useful tools to the community. Among other new biosensor tools, we now offer the jGCaMP7c variant in AAV1. This variant exhibits high contrast between its resting state and its calcium-bound state, which was achieved by lowering the basal fluorescence of the sensor. This “contrast” variant provides improved detection for tracking large populations of neurons in wide-field imaging (Dana et al., 2018).

New voltage sensors

Plasmid Serotype Name
119036  AAV1  pAAV-hsyn-flex-Voltron-ST

DREADDs / Chemogenetics AAV

We have also expanded our inventory of chemogenetic AAV for activating and inhibiting neurons. Minimally-tagged DREADD AAV from the Richie lab are especially useful for studies in non-human primates, where fusion fluorescent proteins can affect DREADD trafficking and localization. The Sternson lab recently deposited PSAM AAV, which encode engineered ligand-gated ion channels that can be activated with FDA-approved drugs.

Recombinase AAV

Finally, we are excited to add Flp-expression AAV to our recombinase AAV inventory. Flp is another useful recombinase that can be used in combination with Cre for intersectional control of specific neuronal populations. We now offer a Flp-expressing AAV, as well as a Cre-dependent Flp-expressing AAV.
