harlan teklad官网TD.02028 TD.02028 TD.96121 动物饲料 胆固醇和胆酸盐来源的纯化高脂饮食
野生型小鼠和大鼠一般对动脉粥样硬化有抵抗力,需要更极端的饮食操作来改变脂蛋白谱,形成轻度动脉粥样硬化(泡沫细胞、脂肪条纹)。现代配方完全是由纯化成分制成的,因为据报道,这种更精细的方法可以减少较少精制和较传统饮食方法引起的胆结石和肝脏损害的发生率。为了在野生型动物中诱导轻度动脉粥样硬化,可对“西方”纯化饲料进行改良,以提高胆固醇(1-1.25%),并添加胆酸钠或胆酸等胆盐。联系我们获得更多的信息,修改,或可能的控制饮食。
添加胆固醇和胆酸盐来源的纯化高脂饮食的例子*:
添加胆固醇的纯化高脂饮食的例子(没有胆酸来源):
- TD.9612121%乳脂(1.25%胆固醇)
研究用途:
主要在野生型小鼠和大鼠诱发高胆固醇血症和轻度动脉粥样硬化(泡沫细胞、脂肪条纹)。
不会助长肥胖。
主要饮食特征:
- 高脂饮食(体重15-20%;脂肪34-45千卡)
- 饱和脂肪酸(SFA>总脂肪酸的55%)
- 乳脂/黄油、可可脂
- 蔗糖(重量占30%-50%)
- 胆固醇(1-1.25%)
- 巧克力源(0.5%)*

*胆酸钠或胆酸有助胆固醇和脂肪的吸收,并可透过胆汁酸合成减少胆固醇的排出。然而,如果你的研究不想包括胆酸盐的来源,没有胆酸盐的饮食是可用的。看见TD.96121为了纯正的饮食TD.94059混合饮食。请与我们联系,了解其他选项。
Examples of purified high fat diets with added cholesterol and cholate source*:
- TD.02028 21% milkfat (1.25% cholesterol, 0.5% cholic acid)
- TD.09237 15% milkfat diet (1% cholesterol, 0.5% sodium cholate)
Examples of purified high fat diets with added cholesterol (without cholate source):
- TD.96121 21% milkfat (1.25% cholesterol)
Research Use:
Induce hypercholesterolemia and mild atherosclerosis (foam cells, fatty streaks) primarily in wild type mice and rats.
Will not promote obesity.
Key dietary features:
- High fat diet (15-20% by weight; 34 – 45% kcal from fat)
- Saturated fatty acids (SFA >55% of total fatty acids)
- Milkfat/butterfat, cocoa butter
- Sucrose (30-50% by weight)
- Cholesterol (1 – 1.25%)
- Cholate source (0.5%)*

*Sodium cholate or cholic acid aid cholesterol and fat absorption and reduce cholesterol disposal via bile acid synthesis. However, if including a cholate source is not desired for your research, diets without cholate are available. See TD.96121 for a purified diet and TD.94059 for a hybrid diet.
