Potent HSP70 attenuation, alternative for apoptozole..
By Eric Dyne on 01/02/2021
Species: Human
Cell Line/Tissue: Microglia

Used this and apoptozole to knock down HSP70 expression. We ended up using Apoptozole for our work but this also worked well. Easy to reconstitute and found to be stable. Confirmed K.D. using qPCR, WB, and IF.

Cytotoxic to microglia at higher dosages (>1uM) observed using a cell viability assay and cell imaging.

VER 155008 induces PARP cleavage in U2OS cells.
By Anonymous on 03/25/2019
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: Osteosarcoma

Human osteosarcoma, U2OS, cells were incubated with VER 155008 (1 microM) for 24 h to follow PARP cleavage using Western blot. Hsp70 inhibition with VER 155008 significantly induced PARP cleavage in U2OS cells.
