Description: Measuring the HIV-1 p24 antigen is a long-established method for lentivirus quantitation. However, the traditional p24 ELISA detects both virus-associated p24 and free p24 generated by 293 cells during transient transfection. Free p24 can account for a substantial portion of total p24 in the supernatant. Therefore, the ELISA typically overestimates the quantity of lentivirus present. Our QuickTiter Lentivirus Titer Kit (Lentivirus-Associated HIV p24) substantially minimizes this problem. A proprietary technology separates the lentivirus from free p24 in solution prior to running the ELISA portion of the assay.

Description: Clone your gene of interest into this Lentiviral Expression Vector, then co-transfect along with lentiviral packaging vectors into a packaging cell line such as 293LTV. This expression vector is compatible with any 2nd or 3rd generation lentiviral packaging system, but due to its design it is best matched with our ViraSafe packaging vectors to produce the highest viral titer.

Description: Making an adenovirus with traditional recombinant methods takes 2-3 months and requires tedious plaque recombination. More recent technologies have shortened this time somewhat, but still produce relatively high amounts of wild type (replication-competent) plaques, levels of which increase with serial amplification. The RAPAd® Adenoviral Expression Systems produce recombinant adenovirus with substantially reduced wild-type virus, while considerably shortening the production time to 2-3 weeks. Serial amplification of adenovirus produced using the RAPAd® system does not significantly increase replication-competent adenovirus levels. The system uses a backbone vector from which the 5' ITR, packaging signal and E1 sequences have been removed. The RAPAd® Universal Adenoviral Expression System (# VPK-250) contains a promoterless shuttle vector to allow you to insert the promoter of your choice along with your gene of interest to maximize gene expression.
