RNA templates produced by CUGA®7 in vitro transcription kit (Nippon Gene). The PURE system (PUREfrex, Gene-Frontier) reaction was carried out at 37 °C for 2 h in the presence or absence of 1 µM IbpA, which included Cy5 labeled tRNAfMet. After protein synthesis, SDS-sample buffer (0.125 M Tris-HCl (pH 6.8), 10% (v/v) 2-mercaptoethanol, 4% (w/v) SDS, 10% (w/v) sucrose, 0.01% (w/v) bromophenol blue) was added and incubated at 95 °C for 5 min. The samples were then separated by SDS-PAGE and detected using a fluorescence imager (Amersham Typhoon RGB, Cytiva) at the 633-nm wavelength. The band intensity was quantified with image analysis software (Image quant, Cytiva).

For FAM-labeled substrates, the final substrate concentration in the reaction was 20 nM. The concentration of H238A in the titration series varied across the gel lanes from 0 µM, 0.027 µM, 0.054 µM, 0.109 µM, 0.217 µM, 0.434 µM, and 0.868 µM in each lane, respectively. Binding reactions were incubated at room temperature in the binding buffer consisting of 30 mM HEPES (pH 7.5) and 100 mM potassium acetate. Samples was analyzed by 8% TBE native PAGE, run at 4 °C for 45 min at 10 V/cm and imaged on an Amersham Typhoon RGB (Cytiva).

A combination of SDS-PAGE and Native-PAGE was used to analyze the aggregation states of the samples. The gels ran on the XCell Surelock Mini-Cell gel tank (Thermo Fisher Scientific), with different running buffers for SDS-PAGE and Native-PAGE.
For SDS-PAGE, total and soluble fractions were prepared and analyzed separately. To prepare the soluble fraction, 50 μL of the sample was centrifuged at 16,900 xg for 5 minutes and the supernatant was used as the soluble fraction. Three μL of Fluorescent Compatible Sample Loading Buffer (Thermo Fisher Scientific) was added to 9 μL of each sample and heated at 95 °C for 15 minutes. Samples were loaded onto a NuPAGE 4-12% Bis-Tris Gel and run at 200 V with NuPAGE MES SDS Running Buffer for 25 minutes (Thermo Fisher Scientific).
For Native-PAGE, 9 μL of the samples were loaded into each well of the Native-PAGE 4-16% Bis-Tris Gel (Thermo Fisher Scientific). Electrophoresis was performed at 150 V with Novex Tris-Glycine Native running buffer for 90 minutes.
Samples containing HiLyte Fluor 488 labeled Aβ42 (green) and Alexa Fluor 647 labeled αS (red), were utilized for fluorescence imaging of SDS- and Native-PAGE gels. The gels were imaged on an Amersham Typhoon RGB (Cytiva, Marlborough, MA, USA) located at the Genomics Core at NYU Center for Genomics and Systems Biology.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
