About Ligation Insert Mass Calculator — shuttle vector

Calculate the ng of insert to add for a target molar insert:vector ratio in shuttle vector. insert ng = ratio × (insert bp / vector bp) × vector ng. The calculation uses insert ng = ratio × (insert bp / vector bp) × vector ng. Why this calculation counts: Ligation and assembly efficiency hinge on the molar ratio of insert to vector — not the mass ratio. Because long fragments contain fewer moles per ng, a 'balanced' mass mix can be wildly off in moles. A 3:1 insert:vector molar ratio is a common starting point. Common pitfalls to avoid: ignoring fragment length when converting ng↔pmol; too little or too much insert; stale ligase or ATP. All maths runs locally in your browser; no data is ever sent to a server. That privacy is exactly why researchers link these calculators from protocols, theses and standard operating procedures.

Frequently asked questions

Any tips specific to this calculation?+

A 3:1 insert:vector molar ratio is a common starting point. Also watch out for: ignoring fragment length when converting ng↔pmol and using a mass ratio instead of a molar ratio.

Is this ligation insert mass calculator — shuttle vector free to use?+

Yes. It is completely free, needs no sign-up, and runs entirely in your browser — there are no usage limits.

What formula does it use?+

It uses insert ng = ratio × (insert bp / vector bp) × vector ng The full worked example is shown beneath the result so you can verify each step.

What are the most common mistakes here?+

In molecular cloning, watch for: using a mass ratio instead of a molar ratio; ignoring fragment length when converting ng↔pmol; too little or too much insert; stale ligase or ATP. This tool shows the working so you can catch these before they cost an experiment.

Does my data leave my device?+

No. All computation happens locally in your browser. Nothing you enter — sequences, concentrations or measurements — is uploaded to any server, so it is safe for confidential work.

Can I cite this tool?+

Yes — use the “Cite this tool” snippet on the page. Many users link these calculators from methods sections, lab SOPs and teaching materials.
