Checking insert:vector ratio
Insert:vector ratio compares the number of insert molecules to vector molecules.
This helps evaluate whether a ligation setup matches the intended molar ratio.

Insert mass: 50 ng
Insert:vector ratio compares the number of insert molecules to vector molecules.
This helps evaluate whether a ligation setup matches the intended molar ratio.
Use this calculator as a planning aid for molecular biology, biochemistry, protein science, cloning, PCR, and routine bench preparation workflows.
Results should be interpreted alongside your protocol, instrument settings, reagent quality, and laboratory safety requirements.

It describes the molar amount of insert DNA relative to vector DNA.
DNA fragments with different lengths have different molecular weights, so ng alone can be misleading.
Yes. Enter your actual insert and vector amounts to estimate the ratio.
Common ratios vary by cloning design; 3:1 is often used as a starting point for insert:vector.
