2-D08 (2’,3’,4’-trihydroxyflavone) is a Sumoylation inhibitor.
Protein sumoylation is a dynamic posttranslational modification involved in various biological processes, such as cellular homeostasis and development. Sumoylation has been reported to play a key role in cancer, though so far there are few small molecule probes available.
In vitro: 2-D08 was identified as a cell permeable, mechanistically unique inhibitor of protein sumoylation. This compound was found to be able to block sumoylation of topoisomerase I in two different cancer cell lines when co-dosed with camptothecin. In addition, futher analyses indicated that 2-D08 inhibited sumoylation via preventing transfer of small ubiquitin-like modifier (SUMO) from the UBC9-SUMO thioester to the substrate without affecting SUMO-activating enzyme E1 (SAE-1/2) or E2 Ubc9-SUMO thioester formation, a mechanism of action that was unprecedented before [1]. Moreover, it was found that 2-D08 at 100 μM could effectively inhibit 10 μM Camptothecin induced Topoisomerase I SUMOylation in breast cancer without affecting overall cellular protein ubiquitinations [2].
In vivo: Up to now, there is no animal in vivo data reported for 2-D08.
Clinical trial: So far, no clinical study has been conducted.

SKP-02数显式电热恒温培养箱的主要技术参数:
型号:SKP-02
工作室规格:250*250*300(功率0.1KW)、300*300*360(功率0.2KW)、420*420*500(功率0.4KW)、500*500*600(功率0.6KW)、600*600*710 (功率0.7KW)
温控范围:室温+5℃~65℃
SKP-02数显式电热恒温培养箱的特点:
1、采用微电脑控制,具有PID自协调功能。
2、独具超温保护、定时功能。
3、优质冷扎板内室,大视角双层观察窗。
4、外壳喷塑。
SKP-02数显式电热恒温培养箱适用于大专院校、生物、农业、科研等部门作储藏菌种、生物培养,SKP-02数显式电热恒温培养箱是进行科研的必须设备。SKP-02数显式电热恒温培养箱智能化的微电脑控制,精细准确。
干燥箱可分为普通式和鼓风式两种。后者在箱内装有一个风机,用以加快热空气的对流,使箱内温度均匀。同时使箱内物品蒸发的水蒸气加速散发到箱外的空气中,以提高干燥效率。
培养箱主要有直热式和隔水式两种:直热式用电热丝直接加热。隔水式培养箱的恒温室被水箱包围,通电后,加热的是水,利用热水的温度使箱内恒温,故为间接加热。这种培养箱温度的上升或下降较为缓慢,更适合于细菌培养箱。
叠多少层没影响。
按ISO标准,每叠不超过6个为宜。
过完年,再开培养箱参数不稳定,两个箱子,co2数值一直在闪~我要养细胞,参数设置的是37℃,5%CO2,请问各位大神有知道咋回事的~还有面板上各种符号啥意思?图中标记的都是在闪的参数
具体可以查看一下说明书。
