Spiking a separate aliquot of each of the same 4 sera
with 6.6 nmol/L 3-epimer 25(OH)[D.sub.3], in the same manner as 24,25[(OH).sub.2][D.sub.3], led to no change in immunoassay-measured total 25(OH)D [mean (SD) 38.6 (9.2) and 39.2 (7.7) nmol/L for unspiked and spiked sera
Because manufacturers of bovine sera
have assured us that nothing is added to bovine serum during the processing of bovine blood, we must assume one or more inhibitors may enter the animals' blood through feeding or the leaching of containers used in the process.
capsulatum antigen, and acute and convalescent sera
tests for antibodies to H.
Third, the authors state that BDE-47 concentrations collected in similar time frames and reported by other studies in milk (83 or 130 ng/g lipid) and sera
(0.63 ng/g lipid, 1988) compare "favorably" with their present sera
results of 46 (1995-1999), 34 (2000-2002), and 5.4 (1985-1988) ng/g lipid.
We obtained sera
from 2 patients taking diclofenac and 2 patients 1 reported case (2) and 1 new case] with antibody against [T.sub.2], [T.sub.3], or their conjugates.
To confirm the presence or absence of anaphylactic antibodies, rat sera
were also tested by PCA essentially as described previously by Ovary (1964).
fPSA concentrations in freshly drawn sera
have been shown to decrease during storage at room temperature and, less rapidly, at 4[degrees]C (12).
No cross-neutralization occurred with human sera
known to contain antibodies to coronavirus strains OC43 and 229E.

Sensitive and specific monoclonal antibody-based capture enzyme immunoassay for detection of nucleocapsid antigen in sera
from patients with severe acute respiratory syndrome.
These IRMAs do not necessarily provide any substantial advantage over a conventional polyclonal IRMA in detecting Tg in TgAb-positive sera
