Instrument Description
The Thermo Scientific NanoDrop™ 1000 Spectrophotometer
measures 1 ul samples with top accurateness and reproducibility. The abounding
spectrum (220nm-750nm) spectrophotometer utilizes a patented
sample assimilation technology that employs apparent astriction abandoned to
hold the sample in place. This eliminates the charge for bulky
cuvettes and added sample ascendancy accessories and allows for apple-pie
up in seconds. In addition, the NanoDrop 1000 Spectrophotometer
has the adequacy to admeasurement awful concentrated samples without
dilution (50X college absorption than the samples abstinent by a
standard cuvette spectrophotometer).
Operation
A 1 ul sample is pipetted assimilate the end of a cilia optic cable (the
receiving fiber). A additional cilia optic cable (the antecedent fiber) is then
brought into acquaintance with the aqueous sample causing the aqueous to arch
the gap amid the cilia optic ends. The gap is controlled to both
source and a spectrometer utilizing a beeline CCD arrangement is acclimated to
analyze the ablaze afterwards casual through the sample. The apparatus is
controlled by PC based software, and the abstracts is logged in an annal
file on the PC.
Applications
UV/VIS spectrophotometry is simple for samples as baby as 1 ul
using the NanoDrop 1000 Spectrophotometer. The baby sample
requirement and affluence of use accomplish the NanoDrop 1000
Spectrophotometer alluringly ill-fitted for measuring:
• Nucleic acerbic absorption and abstention of nucleic acerbic samples up
to 3700 ng/ul (dsDNA) after concoction
• Beaming dye labeling body of nucleic acerbic microarray
samples
• Purified protein assay (A280) up to 100 mg/ml (BSA)
• Expanded spectrum altitude and quantitation of beaming
dye labeled proteins, conjugates, and metalloproteins
• Bradford Assay assay of protein
• BCA Assay assay of protein
• Lowry Assay assay of protein
• Pierce Protein 660 nm Protein Assay
• Cell body measurements
• General UV-Vis spectrophotometry
Patents
The sample assimilation technology acclimated in the NanoDrop 1000
Spectrophotometer is covered beneath US patents 6,628,382 and
6,809,826. Added patents are pending.
