This was a spectral diagram constructed from the data generated on the electron paramagnetic resonance spectrometer of the spin label and albumin complex.
The spin label, 16-doxyl stearic acid, had very high binding constant to albumin .
The interactive spin label
marks a first for the food industry, Huhtamaki said, and Koch Foods has an exclusivity arrangement with Turlock, Calif.-based Stephen Key Design, which holds patent rights to the rotating "Spinformation" label technology from Founder and CEO Stephen Key.
Selected values for variables such as g-factors, hyperfine structure constants, and line widths can then be used to estimate the biophysical characteristics of the-16-doxyl stearic acid spin label. These biophysical characteristics include angle of the spin-labeled molecule axis' precession, polarity of the environment surrounding the spin label, and the rotation speed of the spin label.
Changes in the mobility and accessibility of the spin labels, and the distances between spin labels, enables changes in the secondary and tertiary structure of proteins to be discerned.
The simplest method for characterizing motion of the spin label
is the measurement of the maximum splitting 2[A'.sub.zz] in the EPR spectrum, which corresponds to the difference of the resonance fields between the low-field maximum and the high-field minimum of the spectrum (Fig.
He went on to have a number of well-received releases on London's Lucky Spin label
, under the name Orca, cutting a slew of heavy hardcore tracks while DJ-ing around the west country.

The total angular momentum of the system can be written as F = l + [f.sub.a] + [f.sub.b] = l + f, where [f.sub.a] and [f.sub.b] are the asymptotic total angular momenta of the two atoms, l is the mechanical rotation, f--the vector sum of [f.sub.a] and [f.sub.b]--is a generalized spin label
, and [alpha] uniquely labels the remaining degrees of freedom of the asymptotic atomic scattering states for the 3[S.sup.2]([f.sub.a] = 1) + 3[S.sup.2]([f.sub.b] = 1) collision.
Component 1 was attributed to the spin labels
H-bonded to the headgroups, while component 2 possibly arose from spin labels
H-bonded to water molecules or temporally non-hydrogen-bonded.
An example is Electron Paramagnetic Resonance (EPR) spectroscopy with spin labels
, specially designed chemical "agents" that carry a stable unpaired electron.
