Antibodies are a go-to tool for detecting a protein of interest in cells and tissues. Although antibody production is well established, it’s also a process that’s difficult for individual labs to complete. The nanobody based RANbody platform from the Sanes Lab overcomes this ...
This post was contributed by guest blogger Greg Lohman, a biochemistry researcher at New England Biolabs. When do you need a high fidelity ligase—and when is an alternative ligase a better choice? And what is ligase fidelity anyway? Let’s talk about it. DNA ligases are enzymes ...
Western blots. ELISAs. Immunofluorescence. What do all of these techniques have in common? They all typically require secondary antibodies, frequently of the mouse or rabbit variety. While antibodies certainly aren’t “broken,” their production does require continued animal ...
This post was contributed by guest blogger Matthew J. Niederhuber, a graduate student at UNC Chapel Hill. Chromatin immunoprecipitation followed by high-throughput sequencing, ChIP-Seq, is the go-to method for mapping where a protein binds genome-wide, and has been widely ...
We’ve talked a lot about the quality control process at Addgene by introducing our new sequencing partner seqWell and going into detail about how we use next generation sequencing results to perform quality control on deposited plasmids. We’ve also talked about how our new ...
This post was contributed by guest blogger Jon Backstrom, a biochemist in the Vanderbilt Eye Institute and Tonia Rex's lab. A common strategy to determine the binding kinetics of a purified protein involves immobilization on a solid support. This allows washing away of unbound ...
Promoters control the binding of RNA polymerase and transcription factors. Since the promoter region drives transcription of a target gene, it therefore determines the timing of gene expression and largely defines the amount of recombinant protein that will be produced. Many ...
