Solubility & Handling

Storage instructions -20°C
Solubility overview Soluble in 1.0% NH4OH
Handling

Please note that this product is supplied as a lyophilized solid and may be very hard to visualize.

Amyloid beta peptides are prone to aggregation and as such, there are a variety of published methods for handling amyloid beta peptides.

We recommend using NH4OH with this product - 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.

Important This product is for RESEARCH USE ONLY and is not intended for therapeutic or diagnostic use. Not for human or veterinary use
