Retrovirus Concentration—Concentrate Retroviral Supernatants without Ultracentrifugation

Retro-X Concentrator provides a fast, simple, and highly efficient method for concentrating any retroviral stock including MMLV or MSCV based retroviral supernatants. In the simple protocol, you just mix your retroviral supernatant with the retrovirus concentration reagent, incubate for a short period, and spin the mixture in a standard centrifuge.

You’ll increase your retroviral titer by up to 100-fold in ~1 hr, and obtain excellent recoveries—with no ultracentrifugation.

Far Simpler Than Ultracentrifugation

Compared to ultracentrifugation, the Retro-X Concentrator is more flexible in terms of scale, is easier to use than ultracentrifugation, and requires no specialized equipment.

Scalable for Supernatants of Any Volume, Any Titer

The Retro-X Concentrator reagent is a 4X concentrate, so it can be added to any volume of supernatant containing any amount of virus or any starting titer. At Clontech, scalability has been successful for supernatant volumes up to 250 ml.

Increase Titers By Up To 100-fold

Using the Retro-X Concentrator protocol, we were able to increase the titer of retroviral supernatants for various envelope-pseudotyped retrovirus samples from 46 (amphotropic and 10A1 pseudotypes) to 100-fold (ecotropic and VSV-G), when concentrating them from 10 ml down to 100 µl.
