Therefore, researchers tested a closely related and less hazardous M. marinum, which heterologous expression of two drug activators, became an accurate model to test tuberculosis drugs in. [22] An example examining a more focused drug target is the heterologous expression of ion channel proteins to test different cardiac ion channel drugs that ...
In cell biology and protein biochemistry, heterologous expression means that a protein is experimentally put into a cell that does not normally make (i.e., express) that protein. [1] Heterologous (meaning 'derived from a different organism') refers to the fact that often the transferred protein was initially cloned from or derived from a ...

The main discussion of these abbreviations in the context of drug prescriptions and other medical prescriptions is at List of abbreviations used in medical prescriptions. Some of these abbreviations are best not used, as marked and explained here.
An example of a bacterial expression vector is the pGEX-3x plasmid. The expression host of choice for the expression of many proteins is Escherichia coli as the production of heterologous protein in E. coli is relatively simple and convenient, as well as being rapid and cheap.
Cell-free production of proteins is performed in vitro using purified RNA polymerase, ribosomes, tRNA and ribonucleotides. These reagents may be produced by extraction from cells or from a cell-based expression system. Due to the low expression levels and high cost of cell-free systems, cell-based systems are more widely used. [29]

Ectopic expression is an abnormal gene expression in a cell type, tissue type, or developmental stage in which the gene is not usually expressed. [ 1 ] [ 2 ] The term ectopic expression is predominantly used in studies using metazoans, especially in Drosophila melanogaster for research purposes.
