Product Overview
Large-Scale Transfection Using the 4D-Nucleofector® LV Unit - Experience the latest functional unit for the 4D-Nucleofector® System which expands our proven system to larger-scale transfection.
The LV Unit allows for closed, scalable transfection of larger cell numbers in the range of 1x107 to 1x109 cells. Transfection protocols can be established in smaller scale using the X Unit and subsequently transferred to the LV Unit without the need for re-optimization. Transferability has been tested for various cell types, including human T cells, CHO-S, HEK293-S, or K-562.
Accompanied by GMP grade TheraPEAK® Consumables, a 21CFR part 11 compliant software and IQOQ services the LV Unit is suited to quickly translate research results into a GMP compliant manufacturing process.
There are cell type-specific Optimized Protocols or recommendations available in our knowledge database. In these Optimized Protocols the best Nucleofection conditions are indicated. In addition, we share our experience and knowledge for treatment of individual cell types.

Storage and Content
1 Unit
Lonza GS Xceed™ Cells transfected in small or larger scale show comparable IgG4 titers
For a human IgG4 antibody, similar titers of about 100 µg/mL were achieved in small scale (100 µl) and large scale transfections (1 ml fixed cartridge or 10 mL in flow through LV cartridge) in a 6-day batch culture without any feeds. IgG titers were increased by factor 2.5 when using higher seeding densities (not shown here). Switching to a 14-day fed-batch culture led to titers > 1 mg/mL (not shown here).
Transfection of GFP mRNA into PBMCs
Fresh PBMCs (1x10⁸/mL) were transfected with GFP mRNA (20 µg/mL) using different Nucleofection® Vessels. For the fixed volume vessels (100 µL Nucleocuvette® Vessel and 1 mL Nucleocuvette® Cartridge), cells and mRNA for each sample were mixed separately, pipetted into the vessel and pulsed immediately. For the flow-through LV Nucleocuvette® Cartridge two feeding reservoirs were used to keep cells and mRNA separate as long as possible. Data are based on duplicates (experiment 1) or unicates (experiment 2).
