Aβ1 42 was diluted into PBS buffer at the final concentration of 20 μM, and was mixed with 20 μM Thioflavin T (ThT) and different concentrations of BAFs.
Briefly, proteins were precipitated from lysis buffer with nine volumes of methanol, pelleted by centrifugation, washed with 1 ml of 90% methanol, dried and dissolved in sodium dodecyl sulfate sample buffer at the final concentration of 0.1 μg protein/μl.
5% Acrylamide gel was made as described previously [23] To allow the detection by Coomassie Blue 2 µg of the protein was applied to 5 µg of the RNA in a reconstitution buffer [23] at the final volume of 10 µL.
AβpE3 42 was injected in a buffer solution at the final concentration of 20 μM for a given time at room temperature.
Prepare a solution (49μl): 5μl of 10xKOD buffer (1.2mM MgCl2 at the final concentration) Toyobo), 5μl of 2mM dNTPs, 1μl KOD Dash (2.5U/μl, Toyobo), 2.5μl each of forward and reverse primers (50pmol), 34μl of distilled water, and mix well.
PCR Amplification Prepare a solution (49μl): 5μl of 10xKOD buffer (1.2mM MgCl2 at the final concentration) Toyobo), 5μl of 2mM dNTPs, 1μl KOD Dash (2.5U/μl, Toyobo), 2.5μl each of forward and reverse primers (50pmol), 34μl of distilled water, and mix well.
For control plates, a choline concentration curve ± HC-3 was prepared in assay buffer at 5× the final concentration to be assayed.
The premixes were incubated with labeled probes at final concentrations of 1.2 fmol/μl or 4.5 fmol/μl in the binding buffer containing poly (dI-dC) at the final concentration of 8 ng/μl for 15 min at 15°C.
To isolate fractions enriched in various cell wall components, AIS were subjected to sequential extraction buffers (at final concentration of 30 mg/ml) in constant mixing for 24 hours at room temperature.
When required, a Staphylococcus aureus-specific 70-mer "tracking" oligonucleotide synthesized with a 5'-fluorescein tag was added to the printing buffer at a final molar ratio of 1 80 relative to the M. tuberculosis-specific oligonucleotides.
