Solubility
Alexotech has developed a proprietary method for preparing the amyloid β-peptide with superior solubility. It is, however, crucial to follow our recommended solubilization procedure. To effectively dissolve the amyloid β-peptide, the pH should be briefly raised to between 11 and 12. This can be achieved by adding 20 mM NaOH. At higher peptide concentrations, a greater NaOH concentration may be required due to the peptide’s intrinsic buffering capacity. The pH should therefore always be monitored and adjusted as necessary. After solubilization, the pH can be brought to the desired level using the buffer of choice.
