Application

High molecular weight branched PEI is commonly used in gene delivery due to its high transfection efficiency in a broad range of cells. Branched PEI has been used to successfully deliver genetic material both in vitro and in vivo, while maintaining low cytotoxicity with DNA complexation.

Poly(ethylenimine) (PEI) samples of various molecular weights and pHs were used to transfect endothelial cells to achieve levels of gene expression for comparison. PEIs with nominal molecular weights of 600, 1200, 1800, 10,000, and 70,000 Da were examined at pHs

Several polycations possessing substantial buffering capacity below physiological pH, such as lipopolyamines and polyamidoamine polymers, are efficient transfection agents per se--i.e., without the addition of cell targeting or membrane-disruption agents. This observation led us to test the cationic polymer polyethylenimine

Recent Progress on Nonviral Delivery Carriers for CRISPR/Cas9 Systems

The CRISPR/Cas9 system has recently emerged as a highly specific, efficient, and versatile gene editing technology that can be utilized to build disease models and correct diseased genes. Safe and effective delivery vectors for the CRISPR/Cas9 system are in critical need to enable clinical development and future applications of CRISPR/Cas9 systems. Professor Yang Liu summarizes recent progress in nonviral nanoparticle approaches for CRISPR/Cas9 delivery.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
