Benefits of the GUS Gene Reporter System in Plants
Gene reporters enable valuable insight into gene expression. The GUS gene reporter system is one of the popular and common plant reporter systems. GUS, is short for glucuronidase, an enzyme in the bacterium E. coli. GUS is a good reporter for plants, as it does not occur naturally, and thus, has a low background. With…
Read MoreOptimize Bacterial Protein Expression by Considering these 4 Variables
So, you have successfully cloned your gene of interest and are eager to purify buckets of protein. No matter your eventual application—kinetic experiments using a SPR instrument, structural analysis using X-ray crystallography, or any other experiment—you’ll need to express your protein first. Now, it’s time to put your expression plasmid into E. coli and get…
Read MoreCut My Gene into Pieces– Introduction to Restriction Enzyme Cloning
At the heart of cloning are restriction enzymes. Restriction enzymes are a common tool in any molecular biology lab. Need to know how large your plasmid is? Cut it with a restriction enzyme. Need to chop your genomic DNA into smaller pieces for a southern hybridization or to prepare a library? Use a restriction enzyme.…
