Viral Vector System For gene transduction


Introduction to Virus Packaging System Plasmids

Hgher titer and easier purification process with GeneMedi’s viral vector systems for gene transduction. The gene transduction system including AAV system, adenovirus system and lentivirus system.

AAV vector system (AAV expression system, AAV packaging plasmid system)-Introduction

GeneMedi’s AAV Vector System, also named AAV expression system or AAV packaging plasmid system, is powerful tool for in-vivo gene delivery, gene editing and gene therapy. You can easily produce recombinant AAV (rAAV) paticle in 293T cell line in high titer using GeneMedi’s AAV Vector System. The Genemedi AAV vector system including multiple AAV expression vector plasmids, AAV helper plasmid and the serotypes-specific AAV Rep-Cap plamids.

GeneMedi’s AAV expression vectors have been inserted with differernt expression cassettes, containing kinds of verified protomters and reporters including GFP, zsgreen, RFP, mcherry and luciferase. The GeneMedi’s AAV expression vectors have been proved very suitalble for unique gene overexpression or shRNA-mediated knock-down (also called RNAi (RNA interference ). You can also achieve gene knock-out(KO) or gene editing using our Crispr-cas9-gRNA AAV expression vector.

The serotypes-specific AAV Rep-Cap plamid (AAV-RC plasmid, or called AAV-RC plasmid) contain the AAV2-Rep gene with different serotypes of AAV’s Cap gene(also called AAV capsids gene).

GeneMedi’s AAV Rep-Cap plasmids is including AAV2, AAV5, AAV6, AAV8, AAV9, AAV-PHP.B, AAV-PHP.eB, AAV PHP.s, AAV-Retro (Retrograde), AAV-Anc80 (L65), AAV-DJ, AAV-DJ8. GeneMedi also supplies capsid optimized AAV variant including AAV2 variant(Y444F), AAV2 variant (Y272F, Y444F, Y500F, Y730F), AAV2 variant (Y444F, Y730F, Y500F, Y272F, Y704F, Y252F), AAV2.7m8, AAV8-1m, AAV8-2m, AAV8-3m and some other engineering AAV serotypes not mentioned.

Adenovirus vector system - Introduction

GeneMedi’s adenovirus Vector System, also named the adenovirus expression system or adenovirus packaging plasmid system, is a powerful tool for in-vitro & in-vivo gene delivery, shRNA mediated RNA interference (RNAi) and gene editing. You can easily recombine produce a recombinant adenovirus (r-AdV) particle in HEK293 or HEK293A cell line in high titer using GeneMedi’s adenovirus Vector System.

The Genemedi adenovirus vector system including 2 types of adenovirus packaging plasmids: the adenovirus expression plasmids (adenovirus shuttle vectors) with different promoters and tags, and an adenovirus genome backbone plasmid with E1 region deletion.

Lentivirus vector system - Introduction

GeneMedi’s lentivirus Vector System, also named the lentivirus expression system or lentivirus packaging plasmid system, is a powerful tool for in-vitro & in-vivo gene delivery, shRNA mediated RNA interference (RNAi), gene editing and stable cellline development. You can easily produce a recombinant lentivirus particle in HEK293T or HEK293FT cell line in high titer using GeneMedi’s lentivirus Vector System.

The Genemedi lentivirus vector system including 3 lentivirus packaging plasmids: the lentivirus expression plasmids with different promoters and tags, an envelope protein VSV-G expressing plasmid pMD2G and a packaging plasmid pSPAX2 expressing Gag-pol and Tat.
