Explore stable transfection for the introduction of DNA into cells long-term, including selection markers and antibiotics for stable cell line generation.

While stable transfection ensures that the foreign DNA is incorporated into the host genome for prolonged and consistent gene expression, transient transfection only promotes short-term genomic and proteomic changes separate from the host nucleus and its genome.

2024年8月30日 · In stable transfection, foreign DNA is delivered to the cell nucleus and is integrated into the host genome for expression. Adapted from Kim, T. K 2010 [1]. Transient and stable expression systems have their own set of advantages, disadvantages, and …

2024年5月10日 · Stable transfection facilitates constitutive expression of genetic material in cell lines and is useful for the generation of clonal cell lines, large-scale protein production applications and also for stable expression during gene therapy.

In stable transfection, foreign DNA is either integrated into the cellular genome or maintained as an episomal plasmid. Unlike transient transfection, stable transfection allows the long-term maintenance of the exogenous DNA in the transfected cell and its progeny.

2013年1月3日 · Generating stably transfected cells begins with a transient transfection, followed by an infrequent but important and serendipitous process. In a small proportion of transfected cells, the foreign gene is integrated into the cells’ genome.

2024年4月6日 · The most common method is stable transfection, which involves the insertion of external genetic material into the host genome. This approach ensures the uninterrupted expression of the protein encoded by the foreign material. These typically result in lasting changes to the host’s genome.

Stable Transfection. The goal of stable, long-term transfection is to isolate and propagate individual clones containing transfected DNA that has integrated into the cellular genome. Distinguishing nontransfected cells from those that have taken up exogenous DNA involves selective screening.

Stable transfectants: Cells that have integrated foreign DNA in their genome. Transient transfectants: Foreign DNA does not integrate in the genome but genes are expressed for a limited time (24–96 hours).

Transiently transfected cells are typically harvested 24–96 hours post-transfection and are often used for studying the effects of short-term expression of genes or gene products, performing RNA interference (RNAi)‑mediated gene silencing, or rapidly producing recombinant proteins on a …
