Technical Data
Etoposide (VP-16-213, NSC 141540)
Biochemicals Storage: +20C/+20CShipping:
Potent anti-cancer compound. Induces apoptosis in normal and tumor cell lines.
DNA Topoisomerase II activity inhibitor. Increases Topo II-mediated DNA breakage primarily by inhibiting the ability of the enzyme to religate cleaved nucleic acid molecules. Does not lead to immediate block of DNS synthesis, induces a progressive inhibition of DNA replication.p53 activator.
Blocks the cell cycle between the end of the S phase and the early G2 phase.

Oncoprotein Mdm2 synthesis inhibitor.
Apoptosis inducer through the cytochrome c/Apaf-1/caspase-9 pathway and the Fas-mediated death signaling pathway.
Cell cycle checkpoint activator. Affects gene expression at different levels (chromatin remodeling, transcription and alternative splicing).
Chemotherapeutic compound used in cancers.
Used in conditioning regimen prior to a bone marrow or blood stem cell transplantation.
