Lipofectamine™ LTX Reagent is a plasmid transfection reagent that offers the right balance of potency and gentleness for your cells, resulting in the highest possible transfection efficiencies and viabilities. Lipofectamine™ LTX Reagent is a new, advanced solution for gene expression in both common and challenging cell types. No other plasmid DNA-specific transfection reagent can match the efficiency, convenience, and gentleness of Lipofectamine™ LTX Reagent for transfection of primary, challenging, and sensitive cell lines. Lipofectamine™ LTX Reagent is synthesized from 100% animal origin-free components, making it easy to validate the absence of zoonotic diseases, such as BSE or viruses, in research experiments or cell lines. A certificate of origin may be obtained by contacting Technical Support.

Lipofectamine™ LTX Reagent offers:

• Superior delivery – transfect a broad range of cell types, including primary challenging and sensitive cells, with high efficiency
• Superior performance – combine high transfection efficiency with maximal (>90%) cell viability
• Optimized protocols – rapid, simple protocols provided for most cell lines
• A highly effective reagent to generate stable cell lines

Transfect Primary Cells Efficiently
Primary cells are often difficult to transfect. Lipofectamine™ LTX Reagent, when combined with PLUS™ Reagent, provides the highest level of transfection in primary cells of any lipid- or polymer-based reagent. Many primary cell types have been successfully transfected with Lipofectamine™ LTX including primary neural progenitor cells.

Superior Delivery into Challenging Cells
When it comes to achieving high levels of protein expression in RAW267.3 macrophages, Lipofectamine™ LTX Reagent outperforms competing transfection reagents (see Figure 4). Achieving high-level transgene expression in cells that are traditionally refractory to transfection allows you to obtain results that were previously unattainable.

Broad Compatibility with Cell Lines
In addition to being excellent for transfecting primary and challenging cells, Lipofectamine™ LTX Reagent provides you with the most versatile approach to transfecting established cells lines, including those that are sensitive to other transfection reagents. Use our Transfection Selection Tool to help you select the best transfection conditions for the cells with which you work.

Stable Transfection
Lipofectamine™ LTX strikes the right balance between potency and gentleness, giving you the highest possible percentage of successfully transfected cells. This makes Lipofectamine™ LTX the quickest and easiest reagent for establishing stable transfectants from challenging or refractory cell types.

Simple, Rapid, Serum-compatible Protocol
Lipofectamine™ LTX Reagent offers a streamlined protocol – no need to remove transfection complexes or change/add medium following transfection. A simple, optimization protocol helps you get the best results quickly so you'll spend less hands-on time, and get faster results.

Frequently asked questions (FAQs)

I accidentally left my lipid reagent at room temperature. Can I still use it?

Yes, all of our lipid transfection reagents are stable at room temperature for months.

Find additional tips, troubleshooting help, and resources within our Lipid-Based Transfection Support Center.

Can I use Lipofectamine LTX in RNAi experiments?

We recommend Lipofectamine 3000 for delivery of vector-based RNAi but for direct transfection of synthetic siRNA, we recommend using Lipofectamine RNAiMAX. For in vivo siRNA experiments, we recommend Invivofectamine 3.0 Reagent.

Can I use Lipofectamine LTX for transfection of suspension cells, other hard-to-transfect cells, and primary cells?

We recommend using Lipofectamine 3000 which demonstrates much higher transfection efficiency and protein expression over all other transfection reagents for suspension, hard-to-transfect, and primary cells. Review Lipofectamine 3000 data for over 60 cell lines here https://www.thermofisher.com/us/en/home/brands/product-brand/lipofectamine/lipofectamine-3000.html. For highest transfection efficiencies, we recommend the Neon Transfection System for Jurkat (94%) and K562 (90%) cells.

Can I use Lipofectamine LTX for transfecting plasmid DNA into primary cells?

We have tested four primary cell lines: HuVEC (human ubilical vein endothelial cells), NHFF (normal human foreskin fibroblast), MJ90, and NDHF with transfection efficiencies between 5-25%. Instead, we recommend using Lipofectamine 3000 which shows highest transfection efficiency for all cell types and optimize by varying the DNA and lipid ratio. Alternatively, the Neon Transfection System shows 75-80% transfection efficiency. Please visit our Neon cell specific protocol database for more information: https://www.thermofisher.com/us/en/home/life-science/cell-culture/transfection/transfection---selection-misc/neon-transfection-system/neon-protocols-cell-line-data.html?icid=fr-neon-3

Can I use Lipofectamine LTX for delivery of plasmid DNA and siRNA?

Lipofectamine LTX was designed for delivery of plasmid DNA with minimal cytotoxicity. We do not recommend using it for siRNA delivery. We recommend using Lipofectamine 3000 with the P3000 Enhancer for co-transfection applications.
