# Nanomolar

Nanomolar (nM) is a unit of concentration equal to one billionth of a mole per litre (10⁻⁹ mol/L). Binding affinities and potency values for receptor ligands, including many research peptides, are often reported in the nanomolar range. Preparing nanomolar solutions usually involves serial dilution from a more concentrated stock solution.
