Example sentences for: spr

How can you use “spr” in a sentence? Here are some example sentences to help you improve your vocabulary:

In order to observe the direct-labeling of the SP conjugates to the SPR, CHO cells expressing the rat SPR (rSPR), were incubated with the SP analogs (100 nM) for 2 hrs at 4°C, to prevent internalization of the receptor, rinsed and fixed.
Therefore, an important characteristic of the fluorescent SP analogs is their ability to bind to the SPR and to fluoresce under physiological conditions.
The SPR signal is expressed in resonance units (RU), and 1000 RU is equivalent to a change in surface protein concentration of about 1 ng/mm 2or of about 6 mg/ml in the bulk protein concentration.
Detection of the SPR angle depends on changes in the refractive index (RI) of the medium on the nonilluminated side of the chip.
To resolve these seemingly discrepant results, it is important to recall that in SPR assays, the sensor chips were constantly bathed with a fixed protegrin concentration ranging from 1-20 μM and that in radial diffusion assays, the wells received a fixed initial amount of protegrin (50 ng).
