POLYMER-based In Vivo Transfection Kit
siRNA and plasmid DNA in vivo delivery reagent (mice and rats)
Product Description:
Biodegradable polymer-based in vivo transfection reagent, designed for efficient delivery of siRNA and plasmid DNA to multiple organs, including the lung, liver, kidney, and spleen, with minimal inflammatory response. This versatile reagent is functionally tested in mice and rats, ensuring reliable protein(s) or plasmid DNA/siRNA co-injection and direct subcutaneous tumor injection across various tumor types. Polymer-based in vivo transfection uses synthetic polymers to deliver nucleic acids like DNA or RNA into tissues, offering a safer and more versatile alternative to viral methods. Polyethyleneimine (PEI) is commonly used but can be toxic and induce inflammation, leading to the investigation of other polymers such as PLGA and PBAEs.

DATA
Figure 1. Systemic administration (i.v.) of Polymer-based In Vivo reagent conjugated with siRNA targeting Lamin A/C mRNA or non-silencing control siRNA following the recommended protocol. Tissues were collected and RNA isolated 48 hours after first injection. Samples were analyzed by qRT-PCR for Lamin A/C gene expression levels. Ribosomal RNA levels were used to normalize the Lamin A/C data. Data are means ± SD (n=6).
Figure 2. Intratumoral administration (i.t.) of Polymer-based In Vivo reagent conjugated with siRNA targeting Lamin A/C mRNA or non-silencing control siRNA following the recommended protocol. Tissues were collected and RNA isolated 48 hours after first injection. Samples were analyzed by qRT-PCR for Lamin A/C gene expression levels. Ribosomal RNA levels were used to normalize the Lamin A/C data. Data are means ± SD (n=6).
Figure 3. Systemic administration (i.v.) of Polymer In Vivo Transfection Reagent conjugated with 80 ug of chemically modified siRNA targeting Lamin A/C mRNA or non-silencing control siRNA following the recommended protocol. Tissues (Liver, Brain, Muscle, Kidney, Tumor, Heart, Spleen, Lung) were collected and total protein fraction isolated 72 hours after first injection. Samples were analyzed by Western Blot Analysis for Lamin A/C gene expression levels.
Polymer-based in vivo transfection
Polymer-based approaches for in vivo transfection involve using synthetic polymers to deliver nucleic acids, such as plasmid DNA or RNA, into tissues. This approach is a promising alternative to viral-based methods, which can have safety concerns and limited cargo capacity. One commonly used polymer for in vivo transfection is polyethyleneimine (PEI), which is cationic and can form complexes with negatively charged nucleic acids. These complexes can then be taken up by cells, allowing for expression of the encoded genes. However, PEI can be toxic and induce inflammation, so other polymers such as poly(lactide-co-glycolide) (PLGA) and poly(beta-amino esters) (PBAEs) have been investigated as well. Polymer-based transfection methods have been used in a variety of applications, such as gene therapy, vaccination, and tissue engineering. However, challenges remain in terms of achieving efficient and targeted delivery to specific cell types, minimizing toxicity, and achieving long-term gene expression. Ongoing research in this field is focused on developing more advanced polymer-based delivery systems that can overcome these challenges and improve the efficacy and safety of in vivo transfection.
