Custom DIO Vectors
Use abm’s double-floxed inverse ORF (DIO) vectors for Cre-inducible expression of your gene-of interest! The DIO system allows you to express your target gene only in cells/tissues that also express the Cre recombinase protein, allowing for tissue-specific gene expression. This system is also called Cre-ON, Cre-Switch, FLEx-Cre, Flex-rev (reverse), or Flex-ON. We offer the DIO system in AAV and Lentivector formats.
- Adeno-Associated Virus (AAV) has low immunogenicity & pathogenicity (ideal for gene therapy), can target specific tissue types by using different serotypes, and infects dividing/non-dividing cells.
- Lentiviruses can infect both dividing and non-dividing cells and will integrate stably into the host cell genome, ensuring long-term expression even in cells that are difficult to infect
We also offer high-titer packaging services as well as Cre-expression AAVs and tamoxifen-inducible Cre Lentivirus to support your DIO project from cloning to expression.

Our data speaks for itself:
|Which virus has your lentivirus expression system been derived from? Is it HIV?|
Our lentivirus expression system is derived from Human HIV-1 Virus. It employs third generation self-inactivating recombinant lentiviral vectors with enhanced biosafety features and minimal relation to wild-type Human HIV-1 Virus.
|Is your recombinant AAV replication-deficient?|
Yes, the replication and capsid genes are provided in trans when the AAV is produced, therefore the packaged virion only has the ITR sequences and the gene of interest. Furthermore, the cis plasmid and rep/cap plasmid do not share any regions of homology, preventing the production of wild-type AAV through recombination system.
|Is AAV stable? What is the recommended storage temperature?|
It is recommended to store AAV at -80˚C for long-term storage. For short-term, AAV is stable at 4˚C for up to three weeks without significant loss of activity.
