Cells comprising codon optimized lentiviral particles

摘要

A method of producing a replication defective retrovirus comprising transfecting a producer cell with the following:
iii) a retroviral genome;
iv) a nucleotide sequence coding for retroviral gag and pol proteins; and
iii) nucleotide sequences encoding other essential viral packaging components not encoded by the nucleotide sequence of (ii); characterised in that the nucleotide sequence coding for retroviral gag and pol proteins is codon optimised for expression in the producer cell.
