Lentivirus Concentration Solution (SKU: CC-0013-50, CC-0013-100, CC-0013-200) offers a fast and simple method for concentrating lentiviral stocks. Simply mix your lentiviral supernatant with the concentration solution, incubate, and centrifuge using a standard laboratory centrifuge—no ultracentrifugation required. The protocol is flexible, accommodating both small and large volumes of supernatant. Designed for use with all lentiviral supernatants, it is especially compatible with the Signosis lentivirus system. This solution efficiently increases vector titers (IFU/mL) by 1–2 logs in a short time, with minimal loss of viral material.
