下载地址：http://www.chem17.com/st178406/Info_106414.html This 3rd generation LV packaging plasmid includes gag, coding for the virion main structural proteins; pol, responsible for the retrovirus-specific enzymes; and RRE, a binding site for the Rev protein which facilitates export of the RNA from the nucleus. This plasmid does not include Rev. The third generation packaging system offers maximal biosafety but is more cumbersome, as it involves the transfection of four different plasmids in the producer cells. Please note that most Trono lab lentivectors contain a wt 5’LTR and can be packaged only using the 2nd generation packaging system （as the wt 5’LTR requires TAT for activation）.
载体描述:
Example of a 3rd generation packaging combo: pMDLg/pRRE + pRSV-Rev + pMD2.G.
If you wish to use the 3rd generation packaging system, you need to have a lentivector with a chimeric 5’LTR （e.g. CCL-, RRL-, etc） in which the HIV promoter is replaced with CMV or RSV, thus making it TAT-independent. The lentivectors carrying the chimeric 5’LTR can be packaged into either a 2nd or 3rd generation packaging system.
