How to overexpress a protein
WebEssentially you take a promoter region for a highly expressed gene (viral ones tend to be very strong), and put it in front of your gene of interest. You can also go for other conditional promoters if high expression is toxic. Then your cells start to pump out protein. WebGene expression constructs, such as cDNAs and ORFs, are commonly used to over-express a protein of interest to be analyzed for effect on cellular phenotype, intracellular …

WebApr 9, 2024 · Often, the first step in a molecular biology experiment is to clone (i.e. copy) a gene into a plasmid, then transform this recombinant plasmid back into bacteria so that essentially unlimited copies of the gene (and the plasmid that carries it) can be made as the bacteria reproduce. WebMolecular biology research uses numerous proteins and enzymes, many of which are from expression systems; particularly DNA polymerase for PCR, reverse transcriptase for RNA analysis, restriction endonucleases for cloning, and to make proteins that are screened in drug discovery as biological targets or as potential drugs themselves.
