    Vighi et al29 also used cationic SLNs as a gene vector and the protamine was used as a transfection promoter. It was found that the lower the protamine amount on the surface of the SLN, the lower the efficiency of transfection. In this research, an SLN/protamine/DNA gene delivery system was designed to improve transfection efficiency.Author: Sai-Nan He, Yun-Long Li, Jing-Jing Yan, Wei Zhang, Yong-Zhong Du, He-Yong Yu, Fu-Qiang Hu, Hong Yuan

    The combination of targeting and protamine condensation obviated the need for partial hepatectomy, commonly required to obtain efficient gene delivery in this organ. Since protamine sulfate has been proven to be non-toxic in humans, the novel liver-specific vector described here may be useful for the delivery of clinically important genes to ...Author: M A Arangoa, N Düzgüneş, C Tros de Ilarduya

Cationic Liposome–Protamine–DNA Complexes for Gene Delivery

    https://www.sciencedirect.com/science/article/pii/S0076687903730213
    Liposome–protamine–DNA complex (LPD), as a novel nonviral vector, was developed on the basis of our understanding about the cellular and molecular barriers to cationic lipid–based gene delivery systems.1, 2 Although cationic liposome–DNA complexes (“lipoplexes”) have shown promise in gene transfection both in vitro and in vivo ...Author: Jing Shi Zhang, Song Li, Leaf Huang

    Understanding the internal packing of gene carriers is a key-factor to realize both gene protection during transport and de-complexation at the delivery site. Here, we investigate the structure of complexes formed by DNA fragments and protamine, applied in gene delivery. We found that complexes are charge- and size-tunable aggregates, depending on the protamine/DNA ratio, hundred nanometers in ...Author: Simona Motta, Paola Brocca, Elena Del Favero, Valeria Rondelli, Laura Cantù, Augusto Amici, Daniela ...

    It also improves adenoviral vector-mediated gene transfer as a transfection accelerator. However, there is no consensus as to the mechanism of protamine on gene delivery into cells. To analyze the uptake and subcellular distribution, plasmid and protamine were labeled with FITC and Texas-Red, respectively.Author: Yuri Tsuchiya, Tsuyoshi Ishii, Yoshio Okahata, Toshinori Sato
