Restriction Cloning with CodonCode Aligner
Restriction enzyme-based cloning is a proven and widely used method for inserting DNA fragments into plasmids using specific cut sites. With CodonCode Aligner, you can streamline this process by simulating restriction digests, identifying compatible enzymes, and assembling constructs virtually. The software helps you avoid common mistakes and visualize every step of your cloning workflow, ensuring greater accuracy and efficiency before you step into the lab.
How Restriction Cloning Works in CodonCode Aligner
Decide which enzymes to show by using different options like choosing only unique cutters or selecting your custom enzyme list. Simply select cut sites by clicking on enzymes, or select part of the sequence by clicking on a feature. You can also go back directly to the bases in the cloning view.
The bottom section shows the selected region's overhangs and how vector and insert fit together to form your cloning product. Looking at the bases and highlighting the reading frame in your product makes it easy to see if your clone is in frame:

Best Practices and Tips for Restriction Cloning in CodonCode Aligner
For successful restriction cloning, precision in planning and enzyme selection is key. Here are some essential best practices to help you design clean, efficient cloning workflows — and how CodonCode Aligner can assist in getting it right the first time.
-
Restriction Enzymes
Choose restriction enzymes with compatible ends (e.g., sticky or blunt) to ensure proper ligation and insert orientation. The cloning wizard will flag potential erros and warn you if you do have incompatible cut sites on insert and vector. -
Use Unique Cut Sites
Verify that restriction sites are unique in both the vector and insert to avoid unwanted cuts. To achieve this use Aligner's option to show only enzymes that have unique cut sites. -
Digest Conditions
Use enzymes with compatible buffer conditions when performing double digests to avoid reduced activity. -
Dephosphorylate The Vector
Dephosphorylate the vector after digestion to reduce background from self-ligation. -
Use Virtual Gels
Run digests and ligations on a gel in silico to visualize expected outcomes and troubleshoot problems in advance. Aligner lets you create virtual gels for one or several fragments.
