产品描述
MG-132（MG132，MG 132），也称为Z-Leu-Leu-Leu-al，Z-Leu-Leu-Leu-CHO，是一种强效的，可逆且具细胞渗透性的蛋白酶体Proteasome抑制剂（IC50=100 nM），还是细胞周期和细胞周期蛋白降解所需的钙蛋白酶Calpain抑制剂（IC50=1.2 μM）[1]。A549细胞中MG-132（10μM）有效抑制TNFα诱导的NF-κB活化、IL-8基因转录和IL-8蛋白分泌，通过抑制蛋白酶体介导的IκBα降解来发挥作用[2]。MG-132（10μM）对NF-κB的抑制效应促使人胰腺癌细胞对依托泊甙Etoposide或阿mei素Doxorubicin的凋亡诱导更加敏感[3]。在PC3和DU145雄激素非依赖的前列腺癌（AIPCa）细胞系中MG-132能显著改善六磷酸肌醇（IP6）对细胞代谢的减低能力[4]。
本品以冻干粉形式提供，纯度≥98%，可溶于DMSO或无水乙醇配制成储存液，之后用培养基或生理缓冲液稀释到需要的工作浓度即可。

产品使用
1） 使用前置于室温回温至少20min，并经短暂离心使得粉末/固体落在管底后再溶解。
2） 称取适量粉末溶于无水DMSO配制储存液（比如20 mg/ml，取500μl DMSO 加入10mg MG-132，涡旋混匀，直至完quan溶解）。按照单次用量分装后-20ºC保存，避免反复冻存，至少1个月稳定， 也可置于-80℃延长保存周期。
3） 根据具体实验应用，选择合适的溶剂稀释到所需浓度。体外细胞实验，常用的工作浓度是5-50 µM，处理时间1-24h。本品的具体工作浓度和处理时间请参考相关文献，并根据自身实验条件（如实验目的，细胞种类，培养特性等）进行摸索和优化。

PMID: 11319603 体外研究： 细胞类型（Cell type）：HeLa cells exposed to 10 or 100 J/m2 UV (254 nm) using a UV crosslinker. 药物配制（Preparation）：MG132 dissolved in DMSO and diluted in DMEM. 实验方法（Assay）：HeLa cells were grown to about 60% confluence in DMEM at 37°C in the presence of 5% CO2. MG132 dissolved in DMSO was added (5 µM final concentration). For mock treatment, DMSO alone was added. Cells were incubated for 1 h before UV irradiation. For UV treatment, medium in the Petri dishes was removed, and cells were exposed to 10 or 100 J/m2 UV (254 nm) using a UV crosslinker. Medium containing MG132 or DMSO alone was added back to the respective Petri dishes, and cells were transferred back to the incubator for the time course experiment. |

PMID: 19220323 体内研究： 动物模型（Animal Model）：Experimental murine colitis models: IL-10-deficient (IL-10−/−) mice and dextran sulphate sodium (DSS)-induced colitis 药物配制（Preparation）：MG132 was dissolved in dimethyl sulphoxide (DMSO) and then diluted in 500 µl sterile phosphate-buffered saline (PBS) for injection. 注射剂量（Dosages）：Female IL-10−/− mice at 4 weeks of age were divided into four groups and treated with intraperitoneal injection three times a week as follows: group A, 0·01% DMSO as the control; group B, 0·6 µmol/kg MG132; group C, 3·0 µmol/kg MG132; and group D, 15·0 µmol/kg MG132. All mice were killed after 4 weeks of treatment by cervical dislocation under ether anaesthesia. Female C57BL/6 mice were given 3% DSS (molecular weight 36–50 kDa) in their drinking water for 5 days, and then switched to regular drinking water. Mice were injected intraperitoneally with 15·0 µmol/kg MG132 (prepared in the same way as for IL-10−/− mice) or 0·01% DMSO as the control three times a week from day 0 to the end of the experiment. On day 10, the mice were killed. 给药途径（Administration）：Intraperitoneal (i.p.) injection |
