Transfection is the process of deliberately introducing naked or purified nucleic acids into eukaryotic cells. [ 1 ] [ 2 ] It may also refer to other methods and cell types, although other terms are often preferred: " transformation " is typically used to describe non-viral DNA transfer in bacteria and non-animal eukaryotic cells, including ...
Transformation is one of three processes that lead to horizontal gene transfer, in which exogenous genetic material passes from one bacterium to another, the other two being conjugation (transfer of genetic material between two bacterial cells in direct contact) and transduction (injection of foreign DNA by a bacteriophage virus into the host ...
Transfection is the process of introducing exogenous DNA into eukaryotic cells. [12] It is a more specific term for animal cells, as the process of carcinogenesis in these cells is also included in the definition of transformation. Typically, transfection describes the changes in a cell's genome due to the introduction of foreign DNA. [4]
When genes are delivered to bacteria or plants the process is called transformation and when it is used to deliver genes to animals it is called transfection. This is because transformation has a different meaning in relation to animals, indicating progression to a cancerous state. [ 10 ]
The process of introducing foreign DNA into eukaryotic cells is known as transfection. Electroporation is highly effective for transfecting cells in suspension using electroporation cuvettes. Electroporation has proven efficient for use on tissues in vivo, for in utero applications as well as in ovo transfection. Adherent cells can also be ...
Many methods of transfection and transformation – two ways of expressing a foreign or modified gene in an organism – are effective in only a small percentage of a population subjected to the techniques. [13] [14] Thus, a method for identifying those few successful gene uptake events is necessary.
Insertion of a vector into the target cell is usually called transformation for bacterial cells, [4] transfection for eukaryotic cells, [5] although insertion of a viral vector is often called transduction. [6]
Transduction This is an illustration of the difference between generalized transduction, which is the process of transferring any bacterial gene to a second bacterium through a bacteriophage and specialized transduction, which is the process of moving restricted bacterial genes to a recipient bacterium. While generalized transduction can occur ...
