1% NH4OH solution

1% NH4OH solution which can be used as the solvent for Beta-Amyloid (1-42) and (1-40) peptides.

Please ensure that you are using the appropriate solubilization buffer/ methodology for reconstituting your Beta-amyloid peptide.

When using Beta-amyloid peptides (1-42) or (1-40), you should use 1.0% NH4OH as the solvent followed by buffer (for example 1X PBS).

1. Add 1.0% NH4OH directly to the lyophilized peptide (~70-80 μl for 1mg of peptide). Do not store the peptide in 1.0% NH4OH.
2. Immediately dilute your solution to a concentration of ~1mg/mL or less with 1X PBS or alternative buffer.
3. Vortex gently to mix (less than 1 minute).

Note: This method may not completely remove pre-aggregates. Vortexing may encourage seeding and further aggregation of the peptide.
