Complexation of DNA with Cationic Surfactant
Transfection of an anionic polynucleotide through a negatively charged membrane is an important problem in genetic engineering. The direct association of cationic surfactant to DNA decreases the effective negative charge of the nucleic acid, allowing the DNA-surfactant complex to approach a negatively charged membrane. The paper develops a theory for solutions composed of polyelectrolyte, salt,...
متن کاملComputational modeling of DNA-cationic lipid complexation.
Developments in gene therapy have led to a need for new and more efficient transfection vectors. So far, the use of viruses has received major attention. During the recent years, however, cationic liposomes have emerged as a potential rival for viruses and have several advantages, e.g. nonimmunogenity, low toxicity and a capability to carry larger amounts of DNA. Yet, the properties of cationic...
متن کاملFluoride ion complexation by a cationic borane in aqueous solution.
The phosphonium borane [p-Mes(2)B(C(6)H(4))PMePh(2)](+) complexes fluoride in water containing 10% methanol with a binding constant of 1.0(+/-0.1) x 10(3) M(-1) to afford the zwitterion p-Mes(2)FB(C(6)H(4))PMePh(2).
متن کاملStructural analysis of DNA complexation with cationic lipids
Complexes of cationic liposomes with DNA are promising tools to deliver genetic information into cells for gene therapy and vaccines. Electrostatic interaction is thought to be the major force in lipid-DNA interaction, while lipid-base binding and the stability of cationic lipid-DNA complexes have been the subject of more debate in recent years. The aim of this study was to examine the complexa...
متن کاملStudy on the complexation between DNA and cationic porphyrin derivatives.
A water-soluble cationic porphyrin, 5,10,15,20-Tetra(N-methylpyridinium-4-yl)-21H,23H-porphyrin has been shown to intercalate selectively into the A3-G4 gap of C-quadruplexed DNA d(TTAGGG)4.
