"resonance unit" is a correct and usable phrase in written English.
It refers to a unit of measurement used to describe the degree of resonance or vibration in a system. Example: The scientist used a resonance unit to measure the frequency of the sound waves produced by the machine.
Binding of EGCG (1 µM) to the immobilized cells was monitored in real time by measuring changes in resonance unit.
A resonance unit value of 220 of biotinylated phosphopeptide pSRaf 259 (biotin-MAGGGRQRSTpSTPN) (mode 1 peptide) was coupled to a streptavidin-coated sensor chip (SA5, BIAcore).
A resonance unit value of 296 of biotinylated mode 2 peptide (biotin-MAGGGRLYHpSLP) was also coupled to SA5 and 200 nM each of GST-14-3-3I GST-14-3-3I GST-14-3-3I GST-14-3-3IS-EP buffer, and was injected in the same manner.
Magnetic resonance imaging was performed using a 1.5 T magnetic resonance unit.
The full list of compounds and resonance unit (RU) values are given in Supplementary Table S1.
MRI was performed using a 3.0-T magnetic resonance unit (MAGNETOM Verio, A Tim System; Siemens, Erlangen, Germany).
SPR was performed using a Biacore T200 instrument (GE Healthcare) with CM5 sensor chips coupled with human VEGF165 (Sigma-Aldrich) (~300 resonance units (RU)) using amine-coupling chemistry as described by the manufacturer.
Sensograms in Supplementary Figure S7 represent changes in resonance units on flow cell immobilized with PrP, after subtraction of changes in resonance units on control flow cells (BSA).
This led to approx. 60 resonance units (RU, see Methods section).
Lipid concentrations used in the binding studies were selected to give binding responses of 30-500 resonance units.
Typically, this procedure allowed the coupling of 3000 3500 resonance units (RU) of streptavidin on both flow cells.
