ProFECT for Gene Therapy Delivery:

T&T Scientific’s ProFECT™(mRNA) Transfection Kit is a proprietary and patent-protected lipid-based transfection system designed for safe and effective nucleic acid delivery in a broad range of cell types with high viability and low lipid-associated toxicity.  ProFECT™, a natural lipid composition comprised of non-cationic phospholipid and sterol components, is modified with functional amino acids for highly efficient encapsulation of mRNA and enhanced intracellular delivery.  This easy-to-use lipid formulation is intended for preclinical in vitro studies aimed at translational development of mRNA therapeutics.

Problem: 

A major challenge in nanomedicine is the translation from laboratory formulation to large scale production and has limited clinical success in the field of nanotherapeutics. While translational success is limited with conventional drug delivery systems, the development of safe and efficacious  nanocarriers is crucial to improving the bench-to-bedside success.

Solution: ProFECT(mRNA) Plus

Liposome mRNA Encapsulation (LSE) is a liposome assembly technique to enhance mRNA cargo loading into PEGylated neutral liposomes for improved biocompatibility and pharmacokinetics.  This results in liposomal nanocarriers with efficient nucleic acid encapsulation and enhanced cellular association, while minimizing the cytotoxic effects associated with cationic-mediated transfection. LSE is a quick, easy, reproducible, scalable method for nanoparticle-mediated applied transfection.

Gene therapy has the potential to attenuate a variety of diseases by altering the molecular pathways leading to pathogenesis.  However, the issue of delivery remains a primary hurdle in the successful translation of gene therapeutics.  Cationic liposomes are beneficial experimental gene vectors due to electrostatic-mediated packaging of nucleic acids.  However, the potential for clinical translation is limited in that cationic liposomes are associated with with reduced biocompatibility and poor pharmacokinetics.  PEGylated neutral liposomes (PLPs), comprised of naturally occurring neutral lipids and surface grafted polyethylene glycol (PEG), are considerably more advantageous in terms of biocompatibility and increased drug stability.  However, the addition of the PEG layer reduces the cell-associative properties of PLPs.  Cell-penetrating peptides can be grafted onto the surface of liposomes to enhance cell delivery in order to overcome this so-called “PEG Dilemma”, but assembly must be controlled to prevent CPP-induced drug leakage.
