NanoDrop One User Guide
Please refer to the NanoDrop website for up-to-date kits and protocols for the
NanoDrop One instruments. Follow the assay kit manufacturer's recommendations
for all standards and samples (unknowns). Ensure each is subjected to the same
timing and temperature throughout the assay.
Protein standards for generating a standard curve may also be provided by the kit
manufacturer. Since the NanoDrop One pedestals can measure higher protein
concentrations than traditional cuvette-based spectrophotometers, you may need to
supply your own protein standards at higher concentrations than provided by the
manufacturer. For example, additional standards may be required to ensure the
standard curve covers the dynamic range of the assay and the expected range of
the unknown samples.
NOTICE
• Do not use a squirt or spray bottle on or near the instrument as liquids will
flow into the instrument and may cause permanent damage.
• Do not use hydrofluoric acid (HF) on the pedestals. Fluoride ions will
permanently damage the quartz fiber optic cables.
Before you begin...
Before taking pedestal measurements with the NanoDrop One instrument, lift the
instrument arm and clean the upper and lower pedestals. At a minimum, wipe the
pedestals with a new laboratory wipe. For more information, see
Pedestals.
To measure Protein Pierce 660 standards and samples
1. From the Home screen, select the Proteins tab and then tap
Protein Pierce 660.
2. Specify a

Tip: For this assay, we recommend setting Curve Type to "Linear".
3. Measure blank:
–
Pipette 2 µL reference solution onto lower pedestal and lower arm, or insert
reference solution blanking cuvette into cuvette holder (reference solution
