看了又看
熔点：374-392°C
包装规格：250mg 1g in glass bottle
溶解性：DMSO : 20 mg/mL (61.09 mM; 超声助溶)
储备液保存：-80°C, 6 months -20°C, 1 month (sealed storage, away from moisture and light)
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 (7.64 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 (7.64 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。 3、请依序添加每种溶剂： 10% DMSO→90% Corn Oil Solubility: ≥ 2.5 mg/mL (7.64 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，此方案实验周期在半个月以上的动物实验酌情使用。 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玉米油中，混合均匀。 ＜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：Thiamine levels in the blood of homozygous KO and KI mice fed a conventional diet are decreased to 0.058±0.051 and 0.126±0.092 μM, respectively, at 7 weeks compare to WT mice (0.796±0.259 μM). When WT and homozygous KO and KI mice are fed a Thiamine-restricted diet (Thiamine: 0.60 mg/100 g food), blood Thiamine concentration at 5 and 14 days is markedly decreased to 0.010±0.009 and 0.010±0.006 μM, respectively, compare to WT mice (0.609±0.288 μM). Thiamine concentration in brain homogenate of WT mice fed a conventional diet is 3.81±2.18 nmol/g wet weight, and that of KO and KI is 1.33±0.96 and 2.16±1.55 nmol/g wet weight, respectively. Notably, Thiamine concentration in brain homogenate decreases steadily in KO and KI mice fed a thiamine-restrict diet (Thiamine: 0.60 mg/100 g food) for 5 days (0.95±0.72 nmol/g wet weight) and 14 days (1.11±0.24 nmol/g wet weight), respectively, compare to WT (3.65±1.02 nmol/g wet weight), before the mice presenting an phenotype of disease.
体内研究：WT, homozygous, and heterozygous KO and KI mice fed a conventional diet (thiamine: 1.71 mg/100 g) survive for over 6 months without any phenotype of disease. Homozygous KO and KI mice fed a Thiamine-restricted diet (thiamine: 0.60 mg/100 g food) show paralysis, weight loss, and immobility, and die within 12 and 30 days, respectively. Similarly, homozygous KO and KI mice fed a Thiamine-restricted diet with an even lower percentage of Thiamine (Thiamine: 0.27 mg/100 g food) die within 14 and 18 days, respectively. However, WT and heterozygous KO and KI mice fed a Thiamine-restricted diet (Thiamine: 0.60 mg or 0.27 mg/100g food) survive for over 6 months without any phenotype of disease.
