Studier's T7 expression system uses the T7 promoter to "turn on" a gene of interest and the T7 RNA polymerase to transcribe that gene into messenger RNA (mRNA) so that E. coli ribosomes can use the ...

Protein yield and ease of purification are two important criteria in choosing a system for the expression/ purification of recombinant proteins. The IMPACT (Intein Mediated Purification with an ...

Long before anyone knew anything about COVID-19, scientists studying an obscure enzyme at Brookhaven National Laboratory stumbled upon one of the key building blocks of two vaccines that today are ...

You've probably heard that the first two vaccines approved for battling COVID-19 in the United States use a relatively new approach--injections of simple packets containing mRNA, a genetic material ...

The D-ribose high-affinity transport Operon (RbsDACBKR) o/Escherichia coli encodes the proteins necessary for high-affinity transport and utilization of D-ribose. RbsD encodes a 15 kDa protein and is ...

Xbrane Bioscience has developed a protein expression system for Escherichia coli that eliminates much of the trial and error associated with E. coli strains, which ...

Some proteins are easier to express than others. For some, just clone them into an E. coli vector and let the bacteria do the work. But for others—such as toxic proteins, membrane proteins, ...
