P3 Primary Cell 4D-Nucleofector® LV Kit XL

P3 Primary Cell 4D-Nucleofector® LV Kit XL

Catalog #: V4LP-3020
For larger scale transfection of primary cells, e.g. human T cells or CD34+ hematopoietic stem cells in the LV NucleocuvetteTM Cartridge format when working with the 4D-NucleofectorTM LV Unit


Product Overview

The P3 Primary Cell 4D-NucleofectorTM LV Kit XL* is suited for larger scale transfection of primary cells in the LV NucleocuvetteTM Cartridge format when working with the 4D-NucleofectorTM LV Unit. With the LV NucleocuvetteTM Cartridge a variable volume of up to 20 mL can be transfected. The cartridge is automatically filled and emptied with help of the supplied input and output reservoirs. Alternatively bags can be used. An optional second input allows for separate feeding of mRNA to avoid its degradation.

This kit has been determined to be optimal for transfecting following primary cells and many others that use Solution P3 as optimal NucleofectorTM Solution:

  • B cell (human)
  • CD34+ cell (human)
  • DC (human)
  • ES (human), H9
  • Macrophage (human)
  • Monocyte (human)
  • T cell (human), stim.
  • T cell (mouse), unstim.

The respective cell type-specific Optimized Protocols or recommendations are available under "Instructions" or 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.

*Note: From the five primary cell solutions (P1 – P5) that come with the 4D-NucleofectorTM System only P3 is available for the large-scale formats so far. Solution P3 is suited for most immune and stem cells (e.g. T cells, dendritic cells, CD34 hematopoietic stem cells). For other solutions please contact our Scientific Support.

  • An Innovative, Highly Efficient Method for Transfecting Large Quantities of Primary Human T-cells

    A strong need exists for improved cancer treatment options. Lonza's approach relies on genetically modified, patient-derived cells like T-cells or natural killer cells which express chimeric antigen receptors (CAR) targeting cancer cells.

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).
