The effect of different sample preparatory protocols on the induction of the aryl hydrocarbon receptor (AhR) in the H4IIE–luc reporter gene bio–assay
… of dioxins using the H4IIE-luc-reporter gene assay. The protocols evaluated were either Soxhlet or pressurised liquid extraction (PLE) combined with a manual acid digestion, gel permeation chromatography (GPC) and Florisil fractionation clean-up procedure as well as the automated Total Rapid …

Novel blood platelet diagnostic platform
… of platelets. The final aim is to develop an assay to be used for diagnostic purposes. Blood platelets play a key role in the cardiovascular system. When the en- dothelium of the vessel wall is damaged platelets adhere and become activated, leading to platelet aggregation to maintain …

Determination of Minimum Lethal Level of Toxaphene As A Piscicide in Lakes of North Dakota
… considerable information gained from laboratory bio-assay studies (Surber, 1498; Duedoreff, et al. 1953; Hooper and Grzenda, 1955, et al. 1959). Concentrations indicated by such studies are not necessarily correct for field use. Prevost (1960) pointed out that results from controlled laboratory …

Design, fabrication and characterization of resonant waveguide grating based optical biosensors
… absence of rapid, low cost and highly sensitive biodetection platform has hindered the implementation of next generation cheap and early stage clinical or home based point-of-care diagnostics. Label-free optical biosensing with high sensitivity, throughput, compactness, and low cost, plays an …

Prey-mediated effects of imidacloprid on Laricobius nigrinus (Coleoptera: Derodontidae) and Sasajiscymnus tsugae (Coleoptera: Coccinellidae), two predators of hemlock woolly adelgid
… a commercially available enzyme linked immunoassay (ELISA) kit and a high performance thin-layer chromatography technique for detecting and quantifying imidacloprid residues in hemlock wood and needle tissues. ELISA is advantageous because of its cost, sensitivity, and ease of use. However, …
