| 包装规格: | 1mg in glass bottle |
| 溶解性: | 溶于乙腈 |
| 储备液保存: | -80°C, 6 months -20°C, 1 month |
| 体内实验: | 1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 2.5 mg/mL (8.44 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL。 2、请依序添加每种溶剂: 10% DMSO→90% (20% SBE-β-CD in Saline) Solubility: ≥ 2.5 mg/mL (8.44 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。 2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。 |
| 体外研究: | Deoxynivalenol (0-2 μg/mL, 24 h) 会引发 Caco-2 细胞中丝裂原激活蛋白激酶 (MAPKs) Erk1/2、p38 和 SAPK/JNK 的磷酸化。 Deoxynivalenol (100-4000 ng/mL, 24-72 h) 在 500-4000 ng/mL 剂量下孵育 48 小时和 72 小时后,会降低 IPEC-1 和 IPEC-J2 细胞的活力。 Deoxynivalenol (0-4000 ng/mL, 24-72 h) 在 IPEC-1 和 IPEC-J2 细胞中,浓度为 200 ng/mL 时增加BrdU 的掺入,浓度为2000-4000 ng/mL时减少 BrdU 的掺入。 |
| 体内研究: | Deoxynivalenol (0-5 mg/kg, 灌胃, 每日一次, 14 天) 会以剂量相关的方式增加流涎过多的妊娠大鼠的数量。 Deoxynivalenol (0-5 mg/kg, 灌胃, 每日一次, 14 天) 在 5 mg/kg 剂量下会导致大鼠胎儿胸骨发育异常。 Deoxynivalenol (10-1000 mg/kg; 口服, 腹腔注射; 一次) 对 B6C3F1 小鼠的 LD50 值估计为 78 mg/kg (口服) 和 49 mg/kg (腹腔注射)。 Deoxynivalenol (2-20 mg/kg, 口服, 每日一次, 4 周) 以剂量依赖性方式增加血浆浓度,并减少 B6C3F1 小鼠的体重增加。 药代动力学分析 |
| 细胞实验: | Cell Proliferation Assay Cell Line: Caco-2 cells Concentration: 0-10 μg/mL Incubation Time: 48 h Result: Inhibited the proliferation of cells in a dose-dependent manner. Cell Cycle Analysis Cell Line: IPEC-1 and IPEC-J2 cells Concentration: 200-2000 ng/mL Incubation Time: 24-72 h Result: Increased percentages of pre-G1, S and G2/M phases and decreased of the G0/G1 phase in response to 2000 ng/mL after 48 h in IPEC-1 cells. Decreased the G0/G1 phase in IPEC-J2 cell at the doses of 2000 ng/mL after 48 h. Increased the percentage of pre-G1 in IPEC-1 cells after 72 h. Increased the G2/M phase in IPEC-1 and IPEC-J2 cells at the doses of 2000 ng/mL after 72 h. Apoptosis Analysis Cell Line: IPEC-1 and IPEC-J2 cells Concentration: 200-2000 ng/mL Incubation Time: 6-72 h Result: Increased the caspase 3 activity after 6 h, 8 h, 48 h and 72 h of incubation with 2000 ng/mL. Reduced the caspase 3 activity to the control level after 24 h of incubation with 2000 ng/mL. Western Blot Analysis Cell Line: Caco-2 cells Concentration: 2 μg/mL Incubation Time: 5-240 min Result: Increased the phosphorylation of Erk1/Erk2 during 5 min. Increased the phosphorylation of p38 from 5 to 30 min. Western Blot Analysis Cell Line: IPEC-1 and IPEC-J2 cells Concentration: 200-2000 ng/mL Incubation Time: 48 h Result: Reduced the protein level of ZO-1 at the doses of 2000 ng/mL. |
| 动物实验: | Animal Model: Pregnant rats Dosage: 0-5 mg/kg Administration: i.g., daily, 14 days Result: Reduced feed consumption and mean body weight gain in the 5 mg/kg group . Reduced feed consumption in the 2.5 mg/kg group during 8-14 days. Decreased the number of viable fetuses at 5 mg/kg. Reduced fetal body weight and crown-rump length at 2.5 and 5 mg/kg. Increased the incidence of runts and the average number of fetuses per litter with internal anomalies at 2.5 and 5 mg/kg. Increased the incidence of misaligned and fused sternebrae at 5 mg/kg. Increased the ratios of liver-to-body-weight and kidneys-to-body-weight. |
| 产品描述: | 一种单端孢菌素家族的真菌毒素,通过紧密连接处的细胞旁路来穿过肠粘膜。 Deoxynivalenol is an nhibitor of the synthesis of DNA and RNA. It acts by inducing IL-6 mediated serum hyperelevation of IgA, as well as phosphorylation of extracellular signal regulated protein kinases 1 and 2 (ERK 1,2) and c-Jun N-terminal kinases 1 and 2 (JNK 1,2) in mice. |
| 保存条件: | 2-8°C |
| 注意事项: | 1、为了您的安全和健康,请穿实验服并戴一次性手套操作。 2、以上信息仅做参考交流之用。 |
