Assembly Compatibility
Choose your method, support the standard
Choose your method and assemble your parts the way you want. You can use 3A Assembly, synthesis, Gibson, and more.
Support the standard. BioBrick RFC[10] is the Registry's current standard; all part samples submitted to the Registry must be BioBrick compatible and in the shipping plasmid backbone, pSB1C3.
Standard parts ensure that the Registry can maintain and test all new parts in the same way. Registry members can easily and reliably use and assemble these parts in the future. Standard parts can be moved from one plasmid backbone to another for operation, assembly, measurement, and shipping.
How is a part compatible?
The part's sequence must not contain illegal restriction sites (or other specified sequences) as defined by the assembly standard.
BioBrick compatible parts must not have the following restriction sites:
| Sequence | Type | Enzyme | Note |
|---|---|---|---|
| gaattc | Illegal | EcoRI | |
| tctaga | Illegal | XbaI | |
| actagt | Illegal | SpeI | |
| ctgcag | Illegal | PstI | |
| gcggccgc | Avoid | NotI |
All of these restriction sites belong to the prefix and suffix of the BioBrick assembly standard.
Supported Standards
By supporting an assembly standard, the Registry software can detect and understand the assembly process for parts. This includes:
- Detection of illegal restriction sites in a part's sequence
- Recognizing assembly scars in composite parts
- Identification of a sample's assembly standard, through sequence verification of the sample's prefix and suffix
- Remember, a part can have many samples in the Registry's Repository. Those samples can be in plasmid backbones of different assembly standards.

FAQ
Why is compatibility important?
The iGEM Registry is built on Standard Biological Parts.
- Assembly Standards are one of the facets of the standardization of biology
- All users can easily and reliably assemble and use these parts. They are not conducting an experiment when putting them together.
- BioBrick and Type IIS compatibility allows the Registry to test and maintain all received parts in the same way.
My part is not BioBrick or Type IIS compatible
Before working with your part in the lab (characterizing/measuring), make sure it is BioBrick compatible or Type IIS compatible. If not...
- Synthesize your part to remove any illegal restriction sites, through synonymous substitutions (silent mutations).
- Use site-specific mutagenesis to remove any illegal restriction sites, through synonymous substitutions (silent mutations).
