Abstract
This protocol details the αS PFF assembly.
Attachments
Aggregation
Aggregation
Remove monomer stock from -80 °C and thaw On ice .
Dilute stock to desired concentration (typically 5 undetermined ) to a final volume of 300 µL in autoclaved2 mL centrifuge tubes.
Set thermocycler for continuous shaking (1000 rpm, 37°C ).
Install 2 mL plate.
Run PBS and Protein samples. Take 2 µL aliquot at 0 hr time point. Run ThioT Assay.
Take 2 µL aliquots twice per day for up to 120:00:00 ( 72 hours - 96 hours may be sufficient).
5d
Check ThioT Fluorescence.
Aliquot and store at -80 °C .
ThioT Assay
ThioT Assay
Prepare ThioT stock mixture (8 µg ThioT in 10 µL milliQ H2O).
Prepare working ThioT mixture, 20 µL stock into 1 mL PBS.
Dispense 200 µL working solution into each 2 µL aliquot.
Dispense 200 µL per sample into 96-well, black, corning glass-bottomed plate.
Read Fluorescence Intensity (Ex 450 +/-10; Em 490 +/- 10).
