Advantages:

• Fast Cloning: Transfer GOI from Gateway donor vector to lentivirus vector using Gateway LR Clonase. The latest hORFeome (v7.1) collection has 18,414 human ORFs representing at least 15,415 human genes.
• Reliable: Generate high titer lentivirus in only 5 days.
• Scalable: Lentivirus production can be scaled up to 1 or 5 L of cultured cells.
• Fast Turnaround: ~ 3 weeks are required for cloning, generation of high titer lentivirus and virus purification.
• High Titer and High Yield: Titer from 10⁷ to 10¹⁰ TU/ml. A hollow fiber tangential flow filtration (TFF) system is used to concentrate and purify lentivirus from up to 10 L culture medium (viral supernatant). This system enables us to produce high titer virus stock (10¹⁰ TU/ml) in 1 to 10 ml.
• High Purity: Lentivirus can be further purified using FPLC or ultracentrifugation.
