产品描述 | Coelenterazine (Coelenteramine) is a luminescent enzyme substrate, used for monitoring reporter genes in BRET, ELISA and HTS techniques. |
体外活性 | When monitoring various biological processes, coelenterazine (CTZ) can be catalyzed by luciferases, such as the sea pansy Renilla reniformis (Rluc) and the marine copepod Gaussia princeps (Gluc), which results in emission of blue light. In Gli36-Gluc- or Gli36-Rluc-expressing Gli36 cells, coelenterazine (8 礸/ml) shows a bioluminescence signal. [1] In RIN-5F, 4T1, HCT 116, HEK 293, 293FT, HeLa and INS-1 cells, coelenterazine can be used to assay superoxide anion concentrations. [2] |
体内活性 | In 4T1-implanted mouse, Coelenterazine detects cancer-associated superoxide anion and used to evaluate the role of superoxide anion in cancer cell biology and its role in pathology. [2] |
细胞实验 | Cells are plated at a density of 5×10^4?cells per well into 24-well plates and grown to 80-100% confluency. Just before imaging, media are changed to a colorless solution containing (in mM): 2.7 KCl, 139 NaCl, 8.1 Na2HPO4, 0.7 H2O, 1.5 KH2PO4, 1.8 CaCl2, 1 MgCl2?and 5.5 d-glucose. Cells are preincubated for 15 min in the absence or presence of Pgp modulator, after which Coelenterazine (final concentration of 470 nM) is added directly to the cells. They are for reference only. |
动物实验 | Mice are anesthetized with metofane or isoflurane before tail vein injection of Coelenterazine (4 μg/g) formulated from an ethanol stock diluted in sodium phosphate buffer (50 mM). Bioluminescence imaging is performed on the in vivo imaging system at 2, 6, 8, and 11 min after injection. Anesthesia is maintained during imaging by nose cone delivery of 2.5% isoflurane. After imaging, animals are killed by cervical dislocation; tumors are then harvested and weighed. They are for reference only. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
