摘要:
The invention provides biodegradable, cationic compositions based on cationic α-amino acid-containing PEA, PEUR and PEU polymers for use in preparation of non-viral gene transfer compositions. In the invention gene transfer compositions a poly nucleic acid is condensed with the polymer to form a soluble unit wherein the electrical charge of the poly nucleic acid is neutralized by the polymers. The invention gene transfer compositions can be used to transfect target cells by contact with the target cells.
摘要:
Cationic poly(ester ether amide)s (PEEAs) and compositions comprising PEEAs and biomolecules such as nucleic acids and proteins. Also, a method for intracellular delivery of biomolecules using complexes of the PEEAs and biomolecules. For example, PEEAs can be used as transfection agents for nucleic acids such as DNA and RNA.
摘要:
The present invention relates to tomato plants with increased concentrations of acylsugars, in particular increased concentrations of acylglucoses and/or acylsucroses. The present invention also provides methods for controlling thrips on tomato plants through the use of increased concentrations of acylsugars.
