Nucleic Acid Concentration (A260)

Default factors are standard estimates. Use a custom factor when your extraction method or sample type requires it.

Sample type / factor basis

A260

Dilution factor(Use 1 if undiluted; 10 if 1:10 dilution)

Concentration: 50 µg/mL

Same value: 50 ng/µL (1 µg/mL = 1 ng/µL)

Formula: concentration (µg/mL) = A260 × factor × dilution. Active factor: 50 µg/mL per A260.
