Schematic representation of DOTAP

The proven first-generation transfection reagent DOTAP (1,2-Di-(9Z-octadecenoyl)-3-trimethylammonium propane methylsulfate) in sterile water (concentration 1 mg/ml) is supplied by Biontex as a ready-to-use liposome formulation. Many experiments with DOTAP, as one of the longest-standing known "first-generation" reagents, are described in the scientific literature available, both in vitro & in vivo. Although DOTAP does not offer all the features of modern transfection reagents, in many cases it delivers reliable results.

DOTAP is suitable for transient and stable transfection of mammalian cell lines with DNA (plasmids, bacmids) and modified nucleic acids (antisense oligonucleotides).

 

First-generation transfection reagents

These reagents are generally based on monocationic lipids with a quaternary ammonium ion. They do not feature buffering properties and therefore do not offer the option of endosome buffering, which explains their lower efficiency compared to modern reagents. In addition, serum inhibition is reported for many of these transfection reagents with the exception of DOTAP.

A further feature of these reagents is a generally conventional transfection sequence providing for cell seeding and growth prior to the actual transfection and for change of medium after transfection. As a rule the proportion of DNA to lipids must be optimized carefully to ensure satisfactory results.
