Biological Activity for 17-AAG
17-AAG is an inhibitor of heat shock protein 90 (Hsp90) chaperone activity, and an analog of geldanamycin (Cat. No. 1368). Subsequently inhibits the activity of oncogenic proteins such as p185erbB-2 (IC50 = 31 nM), N-ras, Ki-ras and c-Akt. Antitumor in vivo. Also protects neuroprogenitor cells against stress-induced apoptosis at low concentrations (10 nM) in vitro.

The drug was incubated at 100 nM to inhibit Hsp90.
I used it to down regulate the expression of HSP90. I checked using an antibody for HSP70 and showed upregulation of HSP70 with 10nM of 17-AAG. Easy to use product with informative data sheet. Stable in solution for months.
This is highly cytotoxic to human microglia at a high concentration (>100nM) from our cell viability data. We also confirmed this using imaging.
