Superior mRNA transfection efficiency
Introducing Invitrogen's Lipofectamine MessengerMAX mRNA Transfection Reagent, the mRNA transfection reagent with up to 5X the efficiency of DNA reagents in neurons and primary cell types.
- Amazing transfection efficiency in neurons and primary cell types
- Faster protein expression with no risk of genomic integration
- Up to 10X higher cleavage efficiency using mRNA CRISPRs
Amazing transfection efficiency in neurons and primary cell types
Lipofectamine MessengerMAX mRNA Transfection Reagent delivers amazing transfection efficiency in neurons and a broad-spectrum of primary cells, enabling improved application outcomes and more biologically relevant research. That's because our novel lipid nanoparticle technology is optimized to deliver the highest amount of mRNA possible without the nuclear entry step that is required with DNA.
Faster protein expression with no risk of genomic integration
Transfection of mRNA with Lipofectamine MessengerMAX typically results in faster protein expression with great homogeneity of expression among the transfected cells. Additionally, delivery of mRNA does not require nuclear entry (step 4), which eliminates the risk of genomic integration and transfection efficiency becomes cell cycle independent.

Up to 10X higher cleavage efficiency using CRISPR mRNAs
Lipofectamine MessengerMAX reagent increases the likelihood of cleavage and recombination with Invitrogen GeneArt CRISPR Nuclease mRNA through highly efficient transfection, maximizing the efficiency of CRISPR-driven genetic modifications and simplifying downstream processes.
Figure 5. Cleavage efficiency of various Invitrogen GeneArt CRISPR formats targeting the HPRT locus in Gibco iPS cells in a 12-well format. Invitrogen Lipofectamine 3000 reagent was used to deliver CRISPR nuclease all-in-one plasmid DNA; Lipofectamine MessengerMAX and two leading mRNA delivery reagents were used to deliver an all-RNA CRISPR format (Cas9 mRNA + IVT gRNA). Cleavage efficiency was determined using the Invitrogen GeneArt Genomic Cleavage Detection Kit 72 hours post-transfection.

mRNA Transfection Basics
Ordering information
In order to generate your mRNA transcript, we recommend the following transcription kit:
To help ensure validity of transfection results, we strongly recommend the use of a positive control mRNA, available from various third party vendors, including TriLink BioTechnologies (e.g., EGFP mRNA).
Sustainable packaging
Packaging must protect the product inside—but that doesn’t have to mean sacrificing sustainability. Lipofectamine products are shipped at ambient temperature, diverting 24,000 ft3 of Expanded Polystyrene (EPS) coolers from landfills annually. We reduce the carbon footprint from packaging and shipping these products by 80 tons (CO2 equivalents).
