Stable Gene Expression Cells

Fields of Application

  • Mammalian expression and purification of proteins
  • Functional gene analysis
  • Target identification and validation
  • Generation of reporter cell lines for screening
  • Expression of fluorescent or luminescent proteins for in vivo imaging

Service Comprises

  • Cloning the cDNA of Your Gene of Interest (GOI) in an expression vector
  • Verification of cloning success by DNA-Sequencing
  • Transfection/transduction of Your Cell Line with the resulting expression vector
  • Generation of stable cell pools or clonal cell lines by antibiotic selection.
  • Quantification of  expression of your GOI by qRT-PCR and/or Western Blot

Benefits

  • Maximum flexibility in experimental design
  • Homogenous GOI expression both on mRNA and protein level.
  • GOI Expression adjustable by choice of promoter
  • From receipt of your cDNA to delivery of a functionality tested stable cell pool in less than 6 weeks
  • Funcionality tested frozen cells ready to use

Available Expression Systems

  • Monocistronic or bicistronic expression of your GOI
  • In all bicistronic vectors the expression of your GOI is coupled to that of the gene confering antibiotic resistance

Application Example

Western Blot showing expression of two splice variants of a glycolytic enzyme in stable THP-1 cell pools (Lanes 4 and 5) which both are not expressed in the parental cell line (lanes 3). Lanes 1 and 2 show positive controls.
