The present invention provides nucleic acids encoding recombinant envelope proteins; and packaging cells comprising the nucleic acids, which packaging cells provide for encapsidation of recombinant retroviral vectors. The present invention provides producer cells that produce pseudotyped recombinant retroviral vectors. The present invention further provides methods of purifying pseudotyped recombinant retroviral vectors; and purified pseudotyped recombinant retroviral vectors. The present invention further provides methods of delivering a gene product to an individual. The methods generally involve introducing a subject recombinant retroviral vector into an individual. |
