Insulin was analysed by a solid phase enzyme amplified sensitivity immunoassay (Medgenix INS-ELISA, Biosource, Belgium).
Serum insulin was analysed, using a solid phase enzyme amplified sensitivity immunoassay and also leptin concentrations, using radio-immunoassay.
Using α-1-fetoprotein (AFP) as a model, this novel immunosensor presented amplified sensitivity, good stability, and a broader linear response in two ranges from 0.5 20 ng/mL and 20 200 ng/mL with a detection limit of 0.26 ng/mL, as well as good selectivity and storage stability.
A novel amperometric enzyme immunosensor with amplified sensitivity for the determination of alpha-fetoprotein (AFP) was constructed with layer-by-layer assembly of ZnSe quantum dots (ZnSe QDs)/Azure I/gold nanoparticles (nanoAu /poly (3,4-ethylenedioxythiophene) (PEDOT) on Pt electrode.
Results from piezoresistivity experiments confirm that the nanoreinforced mortars exhibit an increased change in resistivity under cyclic compressive loading, which is indicative of the amplified sensitivity of the material in strain sensing.
Greatly amplified sensitivity was achieved by using GR-TH/HNP-PtCu composite owing to its large specific surface and good electron-transfer ability.
The reasons for such ultrahigh and amplified sensitivity can be attributed to the use of GO and streptavidin-modified Au NPs which not only improved the electron transfer rate, but also increased the amount of capture anti-p53.
These results demonstrate an interaction between hormonal status and cognitive response to stress in female rats, with high estrogen levels being associated with amplified sensitivity to stress.
Thus, the amplified sensitivity of Hif-1α mutant mice to PTH and augmented bone formation response appear to be due to an increase in the functional activity of individual osteoblasts.
