Lipofectamine or Lipofectamine 2000 is a common transfection reagent, produced and sold by Invitrogen, used in molecular and cellular biology. [1] It is used to increase the transfection efficiency of RNA (including mRNA and siRNA ) or plasmid DNA into in vitro cell cultures by lipofection . [ 1 ]
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 ...
Mediating RNA interference in cultured mammalian cells. Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded non-coding RNA molecules, typically 20–24 base pairs in length, similar to microRNA (miRNA), and operating within the RNA interference (RNAi) pathway.
The use of liposomes for transformation or transfection of DNA into a host cell is known as lipofection. In addition to gene and drug delivery applications, liposomes can be used as carriers for the delivery of dyes to textiles, [ 29 ] pesticides to plants, enzymes and nutritional supplements to foods, and cosmetics to the skin.

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 ...
Protocols for chemical method however exist for making super competent cells that may yield a transformation efficiency of over 1 x 10 9. [ 18 ] Damage to DNA – Exposure of DNA to UV radiation in standard preparative agarose gel electrophoresis procedure for as little as 45 seconds can damage the DNA, and this can significantly reduce the ...
Magnet-assisted transfection is a relatively new and time-saving method to introduce nucleic acids into a target cell with increased efficiency. In particular, adherent mammalian cell lines and primary cell cultures show very high transfection rates. Suspension cells and cells from other organisms can also be successfully transfected.
