Molecular biology
Cloning, primers and plasmid maps in the browser
Check a cloning step before you touch a pipette. Design the primers, build the construct and pick the digest that confirms it.
How the work runs
Design primers for your insert, with their melting temperatures side by side.
Hand-off to Plasmid
Cut the vector and insert, and see the ligated construct.
Choose the digest that screens your colonies.

Where the work is kept
In Bench, a Study holds the question, the work you did, the results it produced and the materials and sources behind them, ready for the next time you return.
