Description
Adeno-associated virus and lentivirus are widely used viral vectors in cell and gene therapy applications. However, the process of generation and purification of the viral vectors requires precise quality control to enable safe and reliable dosing during clinical studies or patient care. The ability to accurately quantify vector titers as well as determine contaminations is key to safe and effective AAV-based and LV-based therapies. With the introduction of direct vector lysis solutions for AAV or LV that include reagents for either 100 or 1000 reactions, we now have an optimized and standardized workflow for direct viral vector lysis through to an accurate and precise way of determining the viral titer.
We offer a complete workflow from AAV or LV particle lysis to quantification of the viral titer. The CGT Viral Vector Lysis Kit and the CGT Lentivirus Lysis Kit, with their unique formulas, give a consistent, robust, and accurate determination of the vector titer while saving hands-on time in comparison to the current workflow with a separate sample preparation step. A standardized sample processing step is key to reliable genome titration. It works in conjunction with the QIAcuity Cell and Gene Therapy dPCR Assays, QIAcuity Digital PCR System, QIAcuity Probe PCR Kit (cat. nos. 250272, 250273), QIAcuity OneStep Advanced Probe Kit (cat. nos. 250323, 250324), and QIAcuity Nanoplate 8.5K, offering an end-to-end dPCR workflow comparable to qPCR but delivering absolute quantification of vector genome copies in your sample.
The all-in-one solution for viral vector lysis provides: Standardization of vector lysis with much easier standard operating procedure (SOP) implementation and QC Consistent quantification of titers independent of sample purities or serotypes Broad range of detection down to 2.5 copies/µL in QIAcuity Nanoplate 8.5k The CGT viral vector lysis kits, in conjunction with the QIAcuity Cell and Gene Therapy dPCR Assays and dedicated master mixes running either singleplex or multiplex reactions on the QIAcuity instruments, now deliver a complete viral titer workflow. The principle of the dPCR reaction in nanoplates is described here.
The CGT Viral Vector Lysis Kit (cat. nos. 250272, 250273) is provided with reagents for 100 or 1000 reactions in two boxes for AAV vectors. The kit is suitable for the lysis of AAV2, AAV5, AAV6, AAV8 and AAV9. The lysates are optimized for QIAcuity Cell and Gene Therapy dPCR Assays in combination with the QIAcuity Probe PCR Kit (cat. nos. 250272, 250273). The CGT Lentivirus Lysis Kit (cat. nos. 250323, 250324) is provided with reagents for 100 or 1000 reactions in one box for LV vectors. The lysates are optimized for QIAcuity Cell and Gene Therapy dPCR Assays in combination with the QIAcuity OneStep Advanced Probe Kit (cat. nos. 250323, 250324). These assays enable singleplex as well as multiplex cell and gene therapy applications. The kit does not include restriction enzymes (e.g., Hpall) stated in the protocol (included in the Resources section below).
