Ecotropic Receptor Booster

Temporarily elevate the density of the ecotropic receptor protein mCAT-1 on the surface of any target cell that you wish to infect

The Ecotropic Receptor Booster is used to temporarily elevate the density of the ecotropic receptor protein mCAT-1 on the surface of any target cell that you wish to infect. This allows you, for example, to efficiently transduce human cells with ecotropic retrovirus or lentivirus that otherwise could only infect rodent cells. The technology also allows you to increase the infection efficiency of any cell type that is resistant to viral infection.

The following products are recommended for producing ecotropic pseudotyped virus:

Ecotropic lentivirus—Lenti-X Packaging Single Shots (Ecotropic)
Ecotropic retrovirus—Retro-X Universal Packaging System or EcoPack 2-293 Cell Line

How does it work?

The Ecotropic Receptor Booster consists of a vial of concentrated exosome-like vesicles that are densely coated with the mCAT-1 receptor protein (expand the Details tab in the product table below to view data images). 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 pseudotyped lentivirus or retrovirus.

The Ecotropic Receptor Booster increases the transduction efficiency of cells that are either resistant to infection, or inefficiently infected by ecotropic pseudotyped lentivirus or retrovirus. The Ecotropic Receptor Booster consists of exosome-like particles coated with the mCAT-1 receptor. When applied to target cells, fusion of the exosome-like particles with the host cell plasma membrane temporarily increases surface mCAT-1 receptor, thus allowing for efficient viral transduction.The Ecotropic Receptor Booster renders cells that cannot usually be transduced with ecotropic psuedotyped virus (e.g. human celllines) susceptible to viral infection.

ID Number
8	For Research Use Only, Not for Use in Humans.

This kit provides a complete retroviral vector packaging system for use with any retroviral vector. It is designed to produce virus that can infect dividing cells from a broad range of mammalian and nonmammalian cell types. The GP2-293 Packaging Cell Line contains only the MoMuLV gag and pol genes. The viral envelope portion of the packaging function (env gene) is supplied by transiently co-transfecting one of the Retro-X Universal Packaging Vectors (p10A1, pAmpho, pEco, or pVSV-G) with the retroviral vector. The pQCLIN Retroviral Vector (included in the vector set) can be used as a positive control to constitutively express β-galactosidase in transduced mammalian cells.

The Lenti-X HTX Ecotropic Packaging System allows you to produce very high virus titers from lentiviral vectors for the purposes of transferring exogenous genes into cells and tissues. The Lenti-X HTX Ecotropic Packaging Mix 2 is a proprietary combination of plasmids that expresses the viral proteins necessary for high-efficiency packaging of lentiviral vector transcripts into infectious, ecotropically-pseudotyped, lentiviral particles. The MLV ecotropic envelope glycoprotein enables mouse and rat cells to be transduced with high efficiency. The biodegradable nanoparticle-based Xfect transfection reagent transfers the packaging mix DNA and your lentiviral vector into Lenti-X 293T cells (Cat. No. 632180) with very high efficiency. It is the specific combination of these rigorously optimized components that allows your 293T cell cultures to produce extremely high titers of safe, replication-incompetent lentivirus from any of our Lenti-X System vectors, or from any other lentiviral vector. The Lenti-X GoStix can be used to determine whether virus production is within a usable range or for selecting the best time to harvest your virus.
