The phrase "assay brain" is not correct and does not convey a clear meaning in written English.
It may be intended to refer to analyzing or evaluating cognitive functions, but the phrase lacks clarity and context.
Example: "The researchers aimed to assay brain activity during the experiment, but the terminology was confusing."
Alternatives: "analyze brain" or "evaluate brain".
Right away, I began searching for new tests to assay brain activities.
Microarray analysis was employed to assay brain gene expression in postmortem anterior prefrontal cortex (aPFC) from 42 human cocaine, cannabis and/or phencyclidine abuse cases and 30 control cases, which were characterized by toxicology and drug abuse history.
The levels of Aβ species are presented as µg of Aβ per g of wet brain, taking into account dilution factors introduced by multiple steps throughout the assay (brain homogenization and extraction procedures).
For the luciferase refolding assay, brain homogenates, synaptosomes and synaptic vesicles (with a total protein concentration 0.6, 0.23 and 0.64 mg/ml, respectively) or recombinant His6-SGT, GST-CSP, His6-Hsc70 or His6-CHL1ID (500 nM of each protein) were used.
For LDH release assay brain endothelial cells, pericytes or glial cells were cultured in 96-well plates.
FMRI assays brain activity by indirectly measuring changes in regional blood oxygenation.
We have now evaluated the effects of ETS exposure during pregnancy on brain development by assaying brain tissue at term.
Tissues to be used for biochemical and molecular assays (brain, SC, SN, liver and BM) were isolated and quickly frozen in liquid nitrogen.
For the fibrillization assays, brain homogenate samples were resuspended with 200 μL of Ca2+/Mg2+-free PBS with Complete Protease Inhibitor Cocktail (Roche Applied Science, Indianapolis, IN) and then pooled together.
In both assays, brains were dissected and processed for paraffin-embedded sections.
For all assays, brain-derived neurotropic factor was used at concentrations of 5 ng/ml and MNs were cultured at 37°C with 5% CO2.
