Lentiviral Expression Vectors

Lentiviral Expression Vectors

Our Lentiviral Expression Vectors are designed to work with any 2nd or 3rd generation lentiviral packaging system. However, they are optimized to produce the highest possible viral titers when used in conjunction with our ViraSafe™ Lentiviral Packaging Systems. For best results, choose one of our Complete Expression Systems containing a lentiviral expression vector and a packaging system.

All expression vectors contain an EF-1 promoter which is optimal for general gene expression, with the exception of our promoterless vector which is useful if you wish to clone in a gene-specific promoter along with your gene of interest.

These expression vectors are designed to accommodate large inserts of 7-8 kb, and our promoterless vector can accommodate up to 9 kb.

NOTE: Viral titers typically decrease with large inserts.
