1
METHODS IN CELL BIOLOGY,VOLUME 11, YEAST CELLS
If absorbance measurements are made on various dilutions of a single cell
suspension, in a single, properly functioning, spectrophotometer, it is found that
absorbance is proportional to cell concentration only at rather low cell densities.
2
DNA Sequencing II: Optimizing Preparation and Cleanup
Because nucleic acid absorbance is minimal at 230 nm, absorbance from protein
, phenol, and salt contamination would be more easily detected than at 280 nm,
and thereby provide additional information for the assessment of nucleic acid ...
3
Analytical Chemistry for Technicians, Third Edition
If the pathlengths were different, or if the wall of one cuvette reflects more or less
light than another cuvette, then the absorbance measurement could be different
for that reason, and not because the solution concentration is different.
4
Essentials of Nucleic Acid Analysis: A Robust Approach
Lack of specificity is a major drawback of the UV absorbance method. Any
contaminant present in the sample that absorbs at 260nm will contribute to the
final DNA concentration, potentially leading to overestimation of the actual DNA ...
Jacquie T. Keer, Lyndsey Birch, 2008
5
Molecular Diagnostics: Techniques and Applications for the ...
laser-excited fluorescent signal, while online spectrophotometer detects UV
absorbance of samples during electrophoresis. Since as many as five different
fluorescent dyes can be detected simultaneously in a given sample, CE is quite ...
Wayne W. Grody, Robert M. Nakamura, Frederick L. Kiechle, 2009
6
Treatment Process Selection for Particle Removal
However, it is probably not possible to use UV absorbance to directly determine
the functional groups of these materials (MacCarthy and Rice 1985). Absorbance
due to electron transitions in the double bonds of aromatic chromophores, ...

Environmental Instrumentation and Analysis Handbook
18.2.2 Detection of Absorbance Spectra Although numerous chemicals will
absorb light in the UV or visible wavelength range (including many nutrients,
heavy metals, halogens and organics), many other chemicals of interest for ...
Randy D. Down, Jay H. Lehr, 2005

Calculations for Molecular Biology and Biotechnology: A ...
The absorbance coefficient of a protein is its absorbance for a certain
concentration at a given wavelength in a 1 cm cuvette. Absorbance coefficients
are usually determined for convenient concentrations, such as 1mg/mL, 1%, or
1molar.
Frank H. Stephenson, 2010

Ultraviolet Light in Food Technology: Principles and ...
Molar absorptivity of apple juice, orange juice, and multifruit juice was
determined from the linear regression of absorbance at 254 nm versus
concentration as reported by Oteiza (2005). The following absorptivities were
reported: 0.0715, ...
