Cyagen’s Transgenic Rodent Model Generation Capabilities
| Regular Transgenic | PiggyBac Transgenic | ROSA26 Large-Fragment Knockin | |
|---|---|---|---|
| Integration | Random, multicopy integration | Random, single copy per integration site | Single copy transgene targeted to ROSA26 safe harbor locus |
| Vector construction | Transgenic plasmid or BAC | Transgenic plasmid or BAC | Targeting vector + gRNAs |
| Expression pattern | Variable expression in founders | More consistent expression in founders | Most consistent expression |
| Zygosity | Hemizygous | Hemizygous | Options: Heterozygous and Homo |
| Endogenous effects | Can disrupt endogenous gene expression | Less likely to disrupt endogenous gene expression | Safe harbor site (SHS) does not disrupt endogenous gene expression |
| Available Services | |||
| Turnaround time | 2-5 months | 6-9 months | |
| Donor background | Mouse strains: C57BL/6, FVB 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
