Rat strains: Sprague-Dawley (SD), Long Evans
Please inquire for the availability of additional strains.


Advantages of PiggyBac Transgenic Services

Our proprietary PiggyBac transgenic method has the following advantages over other transgenic approaches:

  • Single-copy integration: Avoids potential gene silencing from multiple copies per integration site
  • Defined region of integration: No loss of transgene sequence (TTAA, transcription unit)
  • Reliability: More consistent expression pattern compared to plasmid-based transgenics
  • Economical: Cost and turnaround time comparable to plasmid-based transgenics
