Great product for inflammation testing..
By Eric Dyne on 09/24/2020
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: Microglia

I used this peptide to induce aggregation along with several other brands. The tocris beta-amyloid reacted the best with Thioflavin-T (1uM) in my experience however, I did find the bachem sample seemed to have the best aggregation patterns.

I used a stationary incubator at 30C and a mixture in an upcoming manuscript that promoted optimal aggregation that was reproducible. I did not use DMSO or water but a special phosphate buffer with alkaline solution.
