Answer
abm's lentiviral vectors are compatible with 2nd and 3rd generation packaging systems. We recommend abm’s Second Generation Packaging Mix (Cat. No. LV003) for users who want to achieve higher titer lentivirus as only 3 plasmids are required for virus production instead of 4 plasmids. We also recommend abm’s Third Generation Packaging Mix (Cat. No. LV053) for users concerned with virus biosafety, as the viral packaging elements are further split into 4 plasmids thus reducing probably of producing wild type virus.
Please note, only packaging mixes produced by abm have been tested in house and therefore carry our guarantee for high titer virus production. If it is desirable to use other packaging plasmids obtained from a different source, the compatibility must be tested and determined by the end user.
