DNA transfection of primary macrophages, glial & dendritic cells
Primary macrophages, glial & dendritic cells
|Number of transfections|
0.5 ml of jetPEI®-Macrophage transfection reagent is sufficient to perform up to 500 transfections in 24-well plates or 160 transfections in 60-mm dishes
4°C, for up to 12 months
150 mM NaCl
jetPEI®-Macrophage transfects primary macrophages, glial & dendritic cells that are considered difficult to transfect. It contains a mannose-conjugated linear polyethylenimine that binds to cells expressing mannose-specific membrane receptors, such as macrophages.
jetPEI®-Macrophage is also the reagent of choice for the transfection of cell lines such as RAW 264.7.
jetPEI®-Macrophage is a Mannose-bearing linear polyethylenimine designed to enhance the transfection of cells expressing Mannose receptors on their membrane. Cell targeting is the result of binding of the Mannose residues to the specific cell-surface receptors, leading to internalization of the DNA complexes.
|Reference Number||Amount of reagent||Amount of NaCl|

Transfection of primary human macrophages
jetPEI®-Macrophage allows successful transfection of macrophages derived from monocytes maturated for 7 days in presence of GM-CSF (Fig.1).
Higher transfection efficiency compared to versatile jetPEI®
Primary human macrophages and murine RAW 264.7 cells express significantly higher protein levels when transfected with jetPEI®-Macrophage (Fig. 2).
Easy to use protocol
The jetPEI®-Macrophage protocol is as simple as the jetPEI® one: Mix the DNA with the reagent to form complexes and simply add the mixture to the cells. jetPEI®-Macrophage is compatible with serum and antibiotics, thus eliminating the need for media change. Protein expression is determined 24 h to 72 h post-transfection.
jetPEI®-Macrophage is perfectly suited for plasmid delivery (DNA, shRNA or miRNA) to cells that express mannose-specific membrane receptors, such as primary macrophages, glial & dendritic cells.

Every batch of jetPEI®-Macrophage is tested in a transfection assay. Typically, transfection of a firefly luciferase gene under the control of the CMV promote gives 109 RLU (relative light unit)/mg of protein. The value for each batch is indicated on the Certificate of Analysis.
