NP-Sticky: Model-Guided Ligation Calculator


Circular Ligation Calculator

You can download this Excel worksheet to facilitate concentration conversion and ligation reaction setup: ligation_worksheet.xlsx

Product Distribution Prediction

This circular ligation calculator can predict product distribution given the input concentrations of vector and insert in the ligation reaction.

Please enter reaction conditions for insert-vector ligation reaction.

Insert Size:bp Molar concentration nM
Mass concentration ng/μl    Volume:μl
Vector Size:bp Molar concentration nM
Mass concentration ng/μl    Volume:μl
Total volume of reaction:μl (only needed when using mass concentrations)
Sticky end free energy Sticky end 1 kcal/mol
Sticky end 2 kcal/mol
Sticky end overhang bases Sticky end 1
Sticky end 2


Ligation Recommendation

Ligation incorporation, efficiency, and accuracy will be calculated over a range of concentrations and molar ratios to allow selection of optimal ligation conditions for specific applications.

Please enter reaction conditions for insert-vector ligation reaction.
