Figure Lengend Snippet: Graph showing the release of alendronate (AL) from ACP053-AL in N-(2-Hydroxyethyl)piperazine-N′-(2-ethanesulfonic acid) (HEPES) buffer (10 mM, pH = 7.0–7.6). All measurements were performed in triplicate and the mean concentrations and corresponding deviations were calculated.

Article Snippet: Phosphoric acid (PA, ≥99.999%), alendronate sodium (Pharmaceutical Secondary Standard), N-(2-Hydroxyethyl)piperazine-N′-(2-ethanesulfonic acid) (HEPES) aqueous solution (1 M, pH 7.0–7.6, sterile-filtered, BioReagent), dimethyl sulfoxide (DMSO) (sterile-filtered BioReagent ≥ 99.7%), and the live/dead double staining kit were purchased from Sigma-Aldrich Sweden AB (Stockholm, Sweden).

Figure Lengend Snippet: ( A ) Surface plasmon resonance (SPR) signal response after injecting 1.25–300 nM streptavidin in HEPES-EDTA buffer over MuOH:Biotin-PEG-thiol (85:15 mol%) SAM sensor surface. Down arrows represents the time of streptavidin injections: 1. = 2.5 nM, 2. = 5 nM, 3. = 10 nM, 4. = 20 nM, 5. = 40 nM, 6. = 80 nM, 7. = 160 nM and 8. = 300 nM. Up arrows represent the injection of buffer without streptavidin. ( B ) Mass areal density curve for streptavidin showing the Langmuir fit over the data points.

Article Snippet: HEPES-EDTA aqueous solution (10 mM HEPES (Sigma), 150 mM NaCl (Fluka), 1 mM EDTA (Sigma), pH 7.4) was used as a buffer solution in all the protein experiments.
