With a peristaltic pump implemented by an injection loop flow system, the bioanalyzer allows the core sensor to be completely exposed to samples.
Human dermal fibroblast cells were exposed to samples at various gradient concentrations of 0.781, 1.562, 3.125, 6.25, 12.5, 25 and 50 μg/mL for 24 h, and cell cytotoxicity was evaluated by MTT assay (Figure 12).
Automated valves and pumps implement an injection loop flow system that allows sensors to be exposed to sample, rinsed, and treated with additional reagents (such as secondary antibodies) under computer control.
Embryos exposed to sample 7 (Muddy Creek, VA) showed activation in both tissues, but with increased sensitivity in the heart valves (1 1,000 dilution) compared with the liver (1 500 dilution).
The chip and the surface of the slide confine a flow chamber, in which lanes of the immobilized biological material are sequentially exposed to sample.
The traditional bacterial killing assay procedure involved growing a microbe either exposed or not exposed to sample (containing killing elements) on agar plates (Buehler et al., 2008; Matson et al., 2006; Rubenstein et al., 2008; Ruiz et al., 2010).
Receptor-based estrogen assays examine the sum of all estrogenic activity in a sample by measuring the response of a cell system exposed to a sample.
The obtained solution was intended to be exposed to the samples.
Embryos were exposed to Neckar River samples from May 2011 (A), September 2011 (B), May 2012 (C) and September 2012 (D).
Abundances of transcripts of pc and tfd were not different in fish exposed to either sample of sediment.
