WebOct 1, 2024 · The reporter gene is transcribed and translated by the transfected cells, and depending on the actual reporter gene used, its activity may be detected directly or indirectly through the ability of its encoded protein to convert a substrate to a detectable product. The latter scenario is illustrated in Figure 1. Figure 1. WebIn the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in …
WebGene expression Transfection is most commonly performed to express a protein of interest in cultured cells (or an animal model) through the use of a plasmid vector or mRNA. Expression of the protein in eukaryotic cells allows the recombinant protein to be produced with proper folding and post-translational modifications required for its function.
