Ecotropic and Amphotropic Receptor Booster technologies are used to temporarily elevate the density of viral receptor proteins on the surface of any target cell that you wish to infect. The technology allows you to efficiently transduce cells that are resistant to viral infection due to low receptor density. The Ecotropic Receptor Booster, for example, allows you to efficiently transduce human cells with ecotropic retrovirus or lentivirus that otherwise can only infect rodent cells.
How Does it Work?
Each receptor booster consists of a vial of concentrated exosome-like vesicles that are coated with either the mCAT-1 receptor protein (ecotropic) or hPit2 receptor protein (amphotropic). When the booster vesicles are applied to your cells (10–20 µl per well of a 6-well plate for ~2 hr) they fuse with the plasma membrane, resulting in an increased level of the receptor on the cell surface. Your target cells can then be more efficiently transduced with ecotropic or amphotropic retrovirus.
