Pre-made viruses have become increasingly accessible and are useful for saving time and avoiding potentially costly set-ups. However, there are many cases where the specific viral particles you need are not available, or the cost of custom viruses are too high for your budget. ...
There are several facilities nationwide where you can obtain excellent quality, high titer rAAV (including Addgene!), but you can also generate rAAVs in your own lab with standard molecular biology tools and tissue culture experience. Here, we’ll go over the basics of rAAV ...
Many neuroscience experiments that require gene expression in a specific cell type rely on transgenic models that express recombinases like Cre or Flp in their cells of interest and recombinase-dependent AAV vectors for selective transgene expression. While this is a powerful ...
Working on the scientific support team at Addgene, I get to see everything that can go wrong with a plasmid. One of the most frequent problems that I help troubleshoot involves viral vectors and plasmids with repeating sequences. Repeating sequences within a plasmid can undergo ...
This post was contributed by guest blogger, Kaustubh Kishor Jadhav, a Research Assistant at MGMs Institute of Biosciences and Technology. If you are reading this article then you probably suspect mycoplasma contamination in your cell culture or you are about to begin a new cell ...
One of the main tenets of our quality control (QC) mantra is to do our utmost to ensure that scientists are receiving the exact materials that they think they are. To address this, several years ago we partnered with Seqwell to establish a next-generation sequencing (NGS) QC ...
Since Addgene began producing AAV vector preparations, we have used quantitative PCR to evaluate the physical titer of our preps. We often repeat this assay to confirm that our results are accurate. But what if we could repeat this assay 10,000 times to ensure that our titers ...
Understanding the biology behind brain development, learning, and behavior poses many challenges in neuroscience with many brain regions, neuronal networks, and specific neuronal populations to consider. To tease apart how different neurons impact a certain output, ...
