None of the animals from either the infected or noninfected cohorts that survived to the end of the experiment were positive by DELFIA
The approval covers assays for PAPP-A and free hCGB run on PerkinElmer's DELFIA
Xpress random access platform.
Comparison of the DELFIA
and RIA methods for measuring luteinizing and follicle stimulating hormones in serum.
PAPP-A and free beta-hCG stability in first trimester serum using PerkinElmer AutoDELFIA and DELFIA
measures intact hCG but not the free [beta] subunit (7,8).
We used the ultra-sensitive DELFIA
rat LH assay (Wallac Oy, Turku, Finland) to measure LH in rodent serum (27).
ADAM12s was measured in 25 [micro]L of serum with a time-resolved fluorescence immunoassay DELFIA
assay kit (PerkinElmer Life and Analytical Sciences).
The Perkin-Elmer DELFIA
time-resolved fluorescence immunoassay (TR-FIA) was selected because of the sensitivity, specificity, and wide linear range offered by this immunoassay compared with conventional enzyme immunoassays.
