β-Amyloid Peptide (1-42) (human) (HB9805) testing

β-Amyloid Peptide (1-42) (human) (HB9805) testing

Acute hippocampal slice (n = 4 Wistar rats, post-natal day 25-30). 3hrs exposure to 2µM amyloid-beta. Field excitatory post-synaptic potential (fEPSP) recordings. Stimulating CA3/Schaffer Collaterals; recording from CA1 field. (left) Evoked fibre volley (FV) amplitude as a function of stimulation magnitude. (right) Evoked fEPSP slope as a function of stimulation magnitude. Analysis by simple linear regression.

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 your buffer (e.g 1X PBS, water or an 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
