(1) Why are G-quadruplexes good at preventing protein aggregation?RNA BiologyDecember 31, 2023Theodore J. Litberg, Rajesh Kumar Reddy Sannapureddi, Zijue Huang, Ahyun Son, Bharathwaj Sathyamoorthy, Scott Horowitzthermal aggregation assay. Circular dichroism and G4 r-value All CD spectra were measured using a Jasco J-1100 circular dichroism spectrophotometer. All samples were made with pre-folded 22 µM G-quadruplex DNA in 10 mM potassium phosphate pH 7.5 buffer
