PEG-Liposome In Vivo Transfection Kit
siRNA, DNA and protein in vivo delivery reagent

PEG-Liposome Invivo Delivery Reagent

Product Description:

PEGylated liposome-based reagent for efficient and safe delivery of various molecules into spleen, kidney, pancreas, liver, and multiple tumor types via systemic administration. The PEG modification ensures the reagent is biodegradable, resulting in no detectable toxicity or any measurable inflammatory response. The complexes formed are stable in serum for at least 16 hours. Reagent can effectively deliver any neutral and negatively charged molecules (si/sh/miRNA), plasmid DNA, and small proteins. This kit has been functionally tested in mice and rats, demonstrating reliability and effectiveness in vivo.

DATA

In Vivo Transfection Reagent Mouse Rat Spleen Kidney Liver Pancreas

Figure 1. Systemic administration (i.v.) of Liposome-PEG 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).

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 PEG-Liposome 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.

PEG-liposomes are a type of lipid-based nanoparticle that consist of a lipid bilayer surrounding an aqueous core, with polyethylene glycol (PEG) chains attached to the surface of the bilayer. PEG-liposomes are used in drug delivery, particularly in cancer treatment, due to their ability to selectively accumulate in tumor tissues. The PEG chains on the surface of the liposomes act as a stealth layer, reducing the clearance of the nanoparticles by the immune system and increasing their circulation time in the bloodstream. This allows for increased accumulation in the tumor tissue, where the liposomes can release their drug payload to target cancer cells. PEG-liposomes have several advantages over traditional chemotherapy drugs. They can selectively target tumor tissues, reducing the toxic effects on healthy tissues. They can also encapsulate hydrophobic drugs that are otherwise difficult to administer, and can provide sustained release of the drug over time. In addition to drug delivery, PEG-liposomes can also be used for gene therapy via encapsulation of plasmid DNA or siRNA and  allowing for the targeted delivery of genetic material to specific tissues. However, there are certain limitations to the use of PEG-liposomes in drug delivery due to highly specialized formulation and manufacturing requirements, otherwise PEG-liposomes can be unstable and prone to aggregation.
