Transfection Reagent

Description

Transfection Reagent is a next-generation cationic lipid-based delivery system optimized for efficient transfection of plasmid DNA, messenger RNA (mRNA), and small interfering RNA (siRNA) into a broad range of eukaryotic cells. Its proprietary lipid nanoparticle formulation ensures strong gene expression results while minimizing cytotoxicity—making it ideal for both routine and advanced applications, including CRISPR and RNA-based therapeutics research.

Features

• High-Efficiency Transfection of mRNA: Comparable in performance to Thermo Fisher’s Lipofectamine™ MessengerMAX™, Biofargo achieves excellent mRNA delivery with minimal toxicity—ideal for mRNA vaccines, gene editing, and protein expression studies.

• Versatile Nucleic Acid Compatibility: Enables efficient transfection of plasmid DNA, mRNA, siRNA, and other nucleic acid formats using a unified protocol.

• Superior Cell Viability: Reduces cellular stress and preserves morphology, ensuring reliable downstream analysis.

• Compatible with Serum and Antibiotics: No need to remove serum or antibiotics, simplifying workflows.

FAQ

Q: Can I deliver single-stranded oligonucleotides with Transfection Reagent?
A: If delivering a single-stranded oligonucleotide alone, it's recommended to use Lipofectamine RNAiMAX Transfection Reagent. However, Transfection Reagent can be used for genome editing when co-delivering Cas9 mRNA, sgRNA, and a donor template (ssDNA or dsDNA).

Q: How do I use Transfection Reagent to deliver both Cas9 mRNA and IVT gRNA together?
A: Transfection Reagent supports co-delivery of Cas9 mRNA with single or multiple gRNAs, providing high transfection efficiency. It is compatible with cleavage detection or selection kits for downstream mutation analysis.

Q: Which cell types can be used with Transfection Reagent?
A: Transfection Reagent shows low cytotoxicity and high efficiency in various cell types, including primary and stem cells, as well as those that are typically difficult to transfect.

Q: When should I use Transfection Reagent over other reagents?
A: Use Transfection Reagent for CRISPR applications requiring the co-delivery of mRNA and gRNA, along with short donor DNA templates. Its flexibility makes it ideal for HDR-based genome editing.

Q: What is Transfection Reagent?
A: Transfection Reagent is an animal-origin-free reagent formulated for delivery of mRNA, small RNA (e.g., gRNA, siRNA, miRNA), and short donor DNA (0.5–1 kb), making it highly suitable for CRISPR genome editing workflows.
