Calculators

The everyday calculations of a molecular biology lab, all in one place.

Works out how much of each reagent to add for any number of PCR reactions.

Calculates relative expression from Ct values (ΔΔCt) and primer efficiency from a standard curve.

Tells you how to dilute a nucleic acid stock to the concentration and volume you need.

Converts between mass, volume and concentration so you can make solutions accurately.

Calculates how much cell suspension to plate to reach your target density per well.

Finds the volume of virus needed to infect your cells at the multiplicity you want.

Measures how well your competent cells took up DNA, in colonies per microgram.
