DNA vector associated with biocompatible low molecular weight polyethyleneimines

摘要

A vector for introducing a nucleic acid into a cell contains a low molecular weight polyethyleneimine (LMW-PEI) and a nucleic acid. A vector for the introduction of a nucleic acid into a cell contains a polyethyleneimine with a molecular weight below 50,000 Da (LMW-PEI) and a nucleic acid. Independent claims are also included for: (A) the preparation of a LMW-PEI; (B) the preparation of a vector containing a LMW-PEI and a nucleic acid; (C) a transfected cell which contains a vector containing a LMW-PEI and a nucleic acid; (D) the preparation of a transfected cell which contains a vector containing a LMW-PEI and a nucleic acid; (E) a medicament containing a LMW-PEI, a vector containing a LMW-PEI and a nucleic acid or a transfected cell containing this vector.
