Biotin and its binding partner avidin are commonly used today in molecular biology for an array of different techniques and protocols. In this post we will discuss the natural role of biotin, biotinylation, the discovery of the biotin-avidin interaction and the uses of ...
A similar genetic code is used by most organisms on Earth, but different organisms have different preferences for the codons they use to encode specific amino acids. This is possible because there are 4 bases (A, T, C, and G) and 3 positions in each codon. There are therefore 64 ...
You’ve spent days and weeks thinking of an amazing project. You’ve written your protocols, designed your experiments, and prepared your reagents. You’re going to engineer the best thing since CRISPR; you are ready to clone! But...how?
The central dogma in molecular biology is DNA→RNA→Protein. To synthesize a particular protein DNA must first be transcribed into messenger RNA (mRNA). mRNA can then be translated at the ribosome into polypeptide chains that make up the primary structure of proteins. Most ...
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 ...
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 ...
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 ...
