TRANSIENT CELL MODELS

Adenovirus transduction is transient due to episomal genome expression, thus circumventing the risk of site specific mutagenesis. Moreover by using high MOI the highest possible gene expression/ knockdown can be achieved.

Adenoviruses are characterized by high cell type accessibility without species limitation and represent a perfect tool for the transduction of primary cells.


Fields of Application

  • For studying short-term effects (up to 10 days) mediated by the expressed transgene/ shRNA
  • to avoid stable genome integration and the risk of site specific mutagenesis
  • If transgene/ shRNA expression has adverse effects on cell growth and/or viability
  • Optimal for non-dividing cells or cells with limited doubling capacity such as many primary cells

SIRION`s benefits

  • Large cloning capacity up to 7.5 kb
  • Quantitative gene delivery and homogeneous expression in most cell types
  • near 100% knockdowns in combination with RNAiONETM
  • Highest gene expression levels by using high MOIs
  • Gene expression levels adjustable by using different MOIs (copy numbers/ cell)
  • Delivered cells are tested to be virus free (BSL-1)
  • From cDNA sequence via custom AV production to delivery of functionality tested cells in less than 6 weeks
