pCDNA3.1-EGFP  was obtained by cloning the EGFP gene into the pCDNA3.1 vector. It was designed for stable and transient expression in mammalian hosts. Most mammalian cells can perform high levels of stable and non replicating transient expression. Human cytomegalovirus immediate early (CMV) promoter is used for high level expression in a wide range of mammalian cells. Abnormal replication in cell lines with latent infection of SV40 or expression of SV40 large T antigen (e.g. COS-1, COS-7).

The GFP in pcDNA3.1-eGFP stands for green fluorescent protein. Deoxyribonucleic acids (DNAs) are typically made up of protein, so it makes sense for a special protein to make up a specific type of DNA add-gene such as the pcDNA3.1.although other means besides cloning would also be openly discussed. In this study, a detailed overview of how pcDNA-eGFP can be produced through cloning is done thanks to the use of secondary sources; a proper review of the pcDNA3.1-eGFP is first carried out to understand this compound. Afterward, the importance of a vector in the cloning process is looked at in detail and finally the cloning system is covered extensivel GFP proteins are generally composed of 238 amino acids with molecular masses of around 26.9 KD [1] and are typically used in the field of molecular biology as one of the many reporter genes. Basically, a reporter gene is a type of gene that researchers, especially in laboratory experiments, use to attach to a pre-specified sequence of the gene (oftentimes an experimental one) such as that of bacteria, plants, animals, and cell cultures. Some of the criteria that researchers use when selecting a reporter gene include, but may not be limited to, having easily identifiable and selectable markers and their ability to introduce changes that tend to be easily spotted under certain conditions. When conducting laboratory experiments in molecular biology, it would be important for researchers to know the different variables involved and the impact that they create on the experimental environment. Therefore, it makes sense to select reporter genes that possess these qualities such as the GFP [1]. In previously published studies involving the use of GFPs, including but not limited to pcDNA3.1, it has been common for researchers to introduce the GFP gene into cells using vector-based systems. In some cases, the researchers also used recombinant viruses (attaching the GFP to them). Being used as a reporter protein, the location of the target protein can be easily identified and expressed. However, in many of the laboratory experiments, the selection market of the GFPs used was not specific enough and there is often no selection market to normalize the transfection among other reactions.
