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 ...
In order to accomplish transfection, one may use integrating viral vectors such as lentiviruses or retroviruses, non-integrating vectors such as Sendai viruses or adenoviruses, microRNAs and a variety of other methods including using proteins and plasmids; [36] one example is the non-viral delivery of transcription factor-encoding plasmids with ...
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 ...
However, because viral vectors frequently lack infectious sequences, they require helper viruses or packaging lines for large-scale transfection. Viral vectors are often designed to permanently incorporate the insert into the host genome, and thus leave distinct genetic markers in the host genome after incorporating the transgene.
Intracellular delivery is a fundamental technique in the study of biology and genetics, such as the use of DNA plasmid transfection to investigate protein function in living cells. [10] A wide range of approaches exist for performing intracellular delivery including biological, chemical and physical techniques that work through either membrane ...
Transformation has a different meaning in relation to animals, indicating progression to a cancerous state, so the process used to insert foreign DNA into animal cells is usually called transfection. [35] There are many ways to directly introduce DNA into animal cells in vitro. Often these cells are stem cells that are used for gene therapy.
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 ...
A selectable marker is a gene introduced into cells, especially bacteria or cells in culture, which confers one or more traits suitable for artificial selection.They are a type of reporter gene used in laboratory microbiology, molecular biology, and genetic engineering to indicate the success of a transfection or transformation or other procedure meant to introduce foreign DNA into a cell.
