Application
Different researchers claim enhanced activity due to different salts.
The TFA salt is what has been the industry standard.
The HFIP makes the beta-amyloid homogenously monomeric.
The NaOH apparently make it monomeric too and is also water soluble, which the TFA salt and HFIP are not.
The HCl salt is supposed to be more biological, as TFA is not found in the body.
By offering the different salts, it lets the researchers duplicate the different assays that have been developed by other researchers (see below).

HFIP: Stine, W.B. et. al. 2003, J. Biol. Chem, 278, 11612

Forme physique
White lyophilized powder. Resuspend in any one of the following solvents: 0.1% TFA, 5 mM HCl, 2 mM NaOH, 1.0 % NH4OH at a concentration of 1 mg/mL. Sonicate for 30 seconds to 1 minute after it has gone into solution. To bring into your solution: After resuspension, add 5x or 10x buffer stock (PBS, TBS) and water to bring to 1x buffer.
Stockage et stabilité
Maintain lyophilized material at -20ºC for up to 12 months after date of receipt. After reconstitution maintain at -20ºC to -70ºC for up to 2 weeks in undiluted aliquots. Avoid freeze/thaw cycles to avoid aggregation.

The occurrence of Alzheimer's disease has been associated with the accumulation of beta-amyloid (β-amyloid) plaques. These plaques activate microglia to secrete inflammatory molecules, which damage neurons in the brain. Thus, understanding the underlying mechanism of microglia activation can provide a
