Andrew Hempstead is a Senior Scientist at Addgene. Andrew's interests include genome engineering and microbiology.
Addgene has recently announced the launch of an open-access recombinant antibody resource called NABOR (Neuroscience AntiBody Open Resource). The antibodies distributed through NABOR are recombinant antibodies expressed from plasmids that have been deposited with Addgene. Here, ...
To respond to environmental conditions, cells must be able to detect extracellular stimuli. One way they do so is through G protein-coupled receptors (GPCRs), receptors that play many roles in signaling processes including smell, taste, sight, inflammation, and ...
In January 2016 we first published a blog post titled: Which Cas9 Do I Choose for My CRISPR Experiment? The three years flew by, but since then, scientists have adapted CRISPR nucleases for many more specific research needs. In this update, we will focus on the most recent ...
While much of CRISPR research has focused on genome editing, numerous discoveries have been made using the Cas9 nuclease in the absence of genomic alterations. These studies utilize a catalytically inactive form of Cas9 known as dCas9 (Jinek et al., 2012). Like Cas9, dCas9 can ...
CRISPR has greatly enhanced the ability of scientists to make genomic alterations, bringing about a revolution in genome engineering, with new techniques rapidly being developed. Performing a CRISPR experiment requires delivery of, at minimum, two components: the Cas9 protein ...
