Expression Vectors or Expression construct: We use an expression vector when our aim is to obtain the protein product of our gene of interest. To get the protein we need to allow the expression of our gene of interest (hence the name expression vector) by employing the processes of transcription and translation.

Expression vectors are extensively used as tools which help in the production of mRNAs and, in turn, stable proteins. They are of much interest in biotechnology and molecular biology for the production of proteins like insulin. Insulin is the chief ingredient in the treatment of the complex disease, Diabetes.

Application filed by Delta Biotechnology Ltd peptide encoding region linked to a heterologus peptide coding region; expression and culture 1999-07-06 Asahi Glass Company Ltd. Secretion signal gene and expression vector containing it. by RT-PCR and were cloned into expression vector pET22b and pBV222.

The vector contains the 25S rDNA sequence of Arxula adeninivorans (rDNA, grey segment) and an expression cassette for the Escherichia coli-derived hph gene in the order: A. adeninivorans-derived TEF1 promoter (TEF1-Pro., black arrow), the hph-coding sequence (HPH, grey segment), Saccharomyces cerevisiae-derived PHO5 terminator (PHO5-Ter., black bar) as selection marker. Once the expression vector gets introduced inside the target cell, then it (vector) starts producing or expressing the protein product that is encoded by the gene it carries.

Expression vectors allow high-level expression of foreign genes in host cells, and through years of development, expression vectors have become a mature and popular biotechnology. Due to its function, the expression vector must contain elements essential for gene expression.

An expression vector contains sequences upstream of the cloned gene that control transcription and translation of the cloned gene. The expression vector shown uses the lacUV promoter, which is very strong, but inducible. To stimulate transcription, the artificial inducer, IPTG, is added. The pET system involves not only an expression vector, but also a genetically engineered host bacteria.

These enzymes break the DNA molecule into a specific nucleotide sequence. It is difficult to overestimate the effect a truly versatile yet simple-to-use expression vector system can have on many fields of plant research and biotechnology. As more and more vectors and vector systems for gene expression in plants become available, it also becomes essential to make their existence and the scope of their use known to the diverse community of plant researchers, basic and applied.
