On P13, mice received either VEGF121b (1 or 10 ng) or Hank's buffered solution in 1 μl intraocular injections using a Nanofil syringe fitted with a 35 gauge needle (WPI, Sarasota, FL, USA) into the left eye under isoflurane anaesthesia.
In a traditional amplification reaction, a highly buffered solution maintains a consistent pH in order to maximize polymerase activity.
The cadmium solution was then added into 50 mL of 0.22 mol/L ammonium acetate [CH3COONH4] buffer solution in a 250 mL polypropylene vessel.
The mass flow rate was estimated through a stopwatch to count how long the buffer solution took to complete a flow loop, and the total weight of the buffer solution in a flow loop was measured by a microbalance.
AFM measurements can be carried out in buffer solution in a physiological medium, which is crucial to study the structure and function of biomolecules, also allowing studying them at work.
Further separation was carried out in the presence of a citric acid/ammonium buffer solution in a weakly acidic medium (pH≈3.5), using ion exchange at elevated temperature.
Larger amounts of radioactive material were later isolated from coral debris of the atoll, which were delivered to the U.S. The separation of suspected new elements was carried out in the presence of a citric acid/ammonium buffer solution in a weakly acidic medium (pH ≈ 3.5), using ion exchange at elevated temperatures; fewer than 200 atoms of einsteinium were recovered in the end.
Since we have a relation of ΔmP t) = (Mc + Mh)( ΔωPL t)/ωL) (for details, see above), the resonant frequency shift measured in buffer solution in a real-time driven by proteolysis is given as ΔωPL t) = ΔωP0[1 – exp kpt)], where ΔωP0 is the steady-state value of frequency shift measured in buffer solution due to proteolysis.
Figure 3A-C shows the resonant frequency shifts, which were measured in buffer solution in a real-time after injection of CTSB, for three different cantilevers in response to proteolysis by protease with three different concentrations, i.e. [CTSB] = 0.28 µM, 0.56 µM, and 0.84 µM, respectively.
The temperature was controlled by keeping the buffer solution in a water bath.
