MG-132 [Z-Leu- Leu-Leu-CHO] is a potent, reversible, and cell-permeable proteasome inhibitor. MG-132 [Z-Leu- Leu-Leu-CHO] is used as a tool for perturbing the proteasome-regulated degradation of intracellular proteins. These proteins processed by the proteasome are involved in inflammatory processes and cell cycle regulation, presenting broad relevance for aldehydic proteasome inhibitors of this type. For instance, MG-132 [Z-Leu- Leu-Leu-CHO] suppresses NF-kappaB activation (at 10 muM) by preventing IkappaB degradation (IC50=3 muM), which blocks the transcription factor from providing chemoresistance to cancer cells. Also, MG-132 [Z-Leu- Leu-Leu-CHO] may act to prevent beta-secretase cleavage of amyloid precursor protein (APP). Additionally, MG-132 [Z-Leu- Leu-Leu-CHO] is an inhibitor of 26S Proteasome and calpain, as well as, an activator of JNK1, c-Jun and c-Fos.Related products include sc-351846 (sc-351846).

Does it supplied as a lyophiled powder? Or can it be weighed and divided? I need to use it in cell cultures, and try to dilute it in PBS because with DMSO or Ethanol it would not be suitable for the culture

Asked by: FlorenciaR
Thank you for your question. This compound is supplied as a crystalline solid and can be dissolved in ethanol (100 mM), or DMSO (100 mM) to make stock solutions.

Rated 5 out of 5 by from YeYe, X. et al. (PubMed 24722419) used MG-132 [Z-Leu-Leu-Leu-CHO], a potent, reversible and selective proteasome inhibitor, to confirm the involvement of ubiquitin-proteasome pathway in miR-21 mediated desmin degradation. MG-132 eliminated the effect of miR-21 on desmin downregulation, indicating that miR-21 promotes desmin degradation through the ubiquitin-proteasome pathway. -SCBT Publication Review
