Achieve high transfection efficiency and high cell viability in a broad range of cell lines using this transfection system

The Neon NxT Electroporation System is an electroporation instrument that offers up to 90% transfection and gene-editing efficiency in extremely difficult-to-transfect cells, including immune, primary, and stem cells. Over 150 cell lines have been tested with optimized ready-to-use conditions for efficiency and viability.

Search the Transfection protocols and citations database for optimized electroporation protocols on different cell lines.

Figure 1. Transfection efficiency with the Neon NxT Electroporation System. Cells were transfected with GFP plasmid DNA or GFP mRNA in 10 μL or 100 μL electroporation reactions. Transfection efficiency is reported as the percentage of GFP-positive cells (n = 3). Note: Naive T cells were only electroporated in 100 μL reactions.

Figure 2. Cell viability following electroporation on the Neon NxT system. Cells were transfected with GFP plasmid DNA or GFP mRNA in 10 μL or 100 μL electroporation reactions. Transfected cells were stained with Invitrogen SYTO Red Dead Cell Stain and assessed for viability on the Invitrogen ATTUNE NxT Flow Cytometer. Cell viability (%) is reported as the mean of 3 measurements. Note: Naive T cells were only electroporated in 100 μL reactions.

(C) Knockout efficiency reported as percentage of initial GFP-positive cells not expressing GFP after electroporation. (D) Post-electroporation viability of knockout cells.

Enhancing genome editing efficiency

Genome editing holds great promise in the pursuit of a greater understanding of human health and disease. A critical, yet challenging step in the genome editing workflow is the effective delivery of CRISPR ribonucleoprotein (RNP), DNA and RNA molecules into the cell line of choice—also known as transfection. As demonstrated above, electroporation is the most widely used delivery method for its ability to achieve high transfection efficiency, even with hard-to-transfect cells.

When used with the Neon NxT Electroporation System, our gene editing reagents and the Neon NxT Resuspension Genome Editing Buffer can help improve gene editing performance with specific payloads like CRISPR Cas9 for knockout or knock-in experiments with mammalian cells including primary, stem, and difficult-to-transfect cells (Figure 3).

Why is the Neon NxT Electroporation System a better alternative to the electroporation cuvette?

Panel A shows a photograph of the Neon NxT Electroporation System tip and panel B shows a photograph of a conventional electroporation cuvette.

Figure 4. Neon NxT pipette tip advantages compared to standard electroporation cuvette. The proprietary biologically compatible (A) Neon NxT tip presents a proven capillary electroporation technology that has important advantages over (B) electroporation cuvettes.

Unlike standard cuvette-based electroporation chambers, the Neon NxT electroporation system uses a proprietary biologically compatible pipette tip chamber that generates a more uniform electric field. This design allows for a better maintenance of physiological conditions resulting in high cell survival compared to conventional electroporation.†

  • Creates a more uniform electric field
  • Maintains a stable pH throughout the electroporation chamber
  • Generates minimal heat
  • Forms fewer ions
  • Reduces shear force experienced by cells

Precisely optimize electroporation parameters for different cell types, cell densities, payloads, and electroporation protocols

Customizable electroporation parameters

With the Neon NxT Electroporation System, you can precisely control the parameters that matter most for your experiment without wasting precious time adjusting those that do not. This transfection system allows you to modify:

  • Pulse voltage
  • Pulse width
  • Number of pulses
  • Cell type
  • Buffer type
  • Payload type

Versatility for different payloads, cell types, and cell densities

Deliver DNA, RNA, or protein to a wide variety of mammalian cells, with the flexibility to transfect 1 x 10to 1 x 107 cells per reaction.

Plan with ease using the TransfectionLab cloud-based app

Invitrogen TransfectionLab, a cloud-based app found on Thermo Fisher Connect, can automatically generate step-by-step guide tailored for each electroporation experiment, starting from the design stage. You can remotely set up multiple plate layouts for up to 384 samples, and any protocol or plate layout saved in the app can be accessed directly on the connected Neon NxT system.

Transfect cells quickly with an easy three-step workflow, a single buffer kit, and an intuitive user interface

Simplified electroporation workflow

Easy to follow and execute, the Neon NxT Electroporation System streamlined workflow requires minimal training and improves consistency and reproducibility.

Using this transfection system, the electroporation process is simple: first, take up cells and plasmid mix into the Neon NxT pipette tip. Second, plug into the pipette holder, and press Electroporate. Finally, pipette the transfected cells back into your culture vessel. As the transfection occurs in the pipette tip, the transfection is completed in just 3 simple steps: Aspirate, Electroporate, Dispense.

Step 1
Prepare cells by suspending them in a Neon NxT buffer. Load cells and payload mix suspended in
Neon NxT buffer into the Neon NxT pipette tip.
Step 2
Apply electrical pulses to cells to deliver the payload in the specialized buffer.
Step 3
Restore growth conditions to allow the transfected cells to recover.
Step 4
Analyze cells
Evaluate: e.g., gene expression, genome editing, silencing, and cell line development

Shorter processing time using this electroporation system

In addition to simplifying the workflow, our proprietary electroporation technology shortens the overall process to 10–15 minutes, compared to a conventional electroporation system as the transfection occurs in the Neon NxT pipette tip.†

A single buffer kit for many mammalian cell types

Avoid the hassle of searching for a buffer kit that will work with your cell line. We have simplified the process with one buffer kit that is compatible with over 150 mammalian cell lines. We recommend using Invitrogen Neon NxT Resuspension R Buffer at voltages below 1,900 V and Invitrogen Neon NxT Resuspension T Buffer at higher voltages.

Minimize sample transfer loss and contamination risk of valuable cells with unique and compact electroporation instrument design

Minimal sample transfer loss

Your samples are precious, but some volume is inevitably lost during transfer to and from a conventional electroporation cuvette. Electroporation on the Neon NxT Electroporation System occurs within the pipette tip, helping to minimize sample loss and the amount of shear force experienced by cells.

Minimal sample contamination

The compact footprint of the Neon NxT system, including the pulse generator and pipette station, makes it small enough to fit in most biosafety cabinets (BSCs). Your samples always stay within the aseptic area while using the instrument, helping reduce the risk of contaminating precious cells. The Neon NxT system also has a new cable management feature that makes using it in the BSC hassle-free.
