We also used the measured 24,25[(OH).sub.2][D.sub.3] concentration in sera
from the NANS subset (with and without the mean factor of 2.79) to adjust the immunoassay-measured total serum 25(OH)D concentration and compare the mean to that from LC-MS/MS estimates.
In fact, there is no reliable method for accurately measuring the concentration of bilirubin in calibrators and controls consisting of UBIL, DTB, or both in bovine sera
from commercial sources.
We obtained convalescent sera
19-21 days after the acute sera
; these samples were tested in parallel with the acute sera
(2004), the analyzed sera
were not collected in such a way as to be representative of the general U.S.
With the Vitros F[T.sub.3] assay, F[T.sub.3] concentrations in 2-fold diluted control sera
were 96% (1.1%) [mean (SD)] of those in the nondiluted sera
, and in 2-fold diluted sera
from 2 patients taking diclofenac, F[T.sub.3] concentrations were 95.9% and 96.3% of those in the nondiluted sera
were used for the quantification of [beta]-LG by ELISA.
A blinded panel of 50 samples comprising sera
from healthy persons, patients infected with other human coronaviruses (OC43 and 229E), patients infected with influenza virus, and persons who were convalescent from SARS was provided by the Health Protection Agency (HPA), United Kingdom, for the validation of our pseudotype neutralization assay.
It has been suggested (17) that quantitative assessment of Tg in TgAb-positive sera
may be achieved by determination of the recovery of known amounts of Tg added to TgAb-positive samples.
We also found that the addition of sera
protected the cells from the adverse effects of chlorpyrifos and that the effect could be reproduced by addition of albumin.
Patient 1,46 years old, and patient 2, 25 years old, had a flulike syndrome with maculopapular exanthema; WNV seroconversion was seen on a pair of sera
collected on days 3 and 16 for patient 1, and days 3 and 12 for patient 2, after onset of fever.
from healthy individuals, TfR-Tf eluted as a single peak at ~330 kDa (Fig.

collected throughout Europe.
were treated with 1,1,2-trichloro-trifluoroethane to remove lipids, passed over a HiTrap Protein G column (Pharmacia Biotech) to remove immunoglobulins, and then passed over a HiTrap Blue column (Pharmacia Biotech) to remove human serum albumin.
