Harlan TD.88137 高脂饲料 Adjusted Kcal Diet (42% from fat)
A staple of atherosclerosis research
More than 25 years ago, our nutritionists collaborated with researchers at Rockefeller University to develop a diet with features of a ‘Western Diet’ to characterize and enhance atherosclerosis development in their newly generated Apoe deficient mouse model. With over 200 unique users worldwide, TD.88137 continues to be fed to genetically modified cardiovascular models to accelerate and enhance hypercholesterolemia and plaque formation.

Selected nutrient information1
Key points from the literature
TD.88137 has been used to accelerate atherosclerosis development in Apoe and Ldlr deficient models:
++In Apoe deficient mice, plasma cholesterol triples to >1500 mg/dL within three weeks (1, 2). Foam cell and lesion development occurs within 6-10 weeks
(2-4). Fibrous plaque formation is observed at 15 weeks with the development of fibrous caps after 20 weeks (2).
++Ldlr deficient mice fed for two weeks increase plasma cholesterol to >800 mg/dL and triglyceride to >300 mg/dL (5). After six weeks of feeding, hyperglycemia, hyperinsulinemia and dyslipidemia develop with small foam cell lesions in the aortic
arch (6, 7).
With over 420 citations, uses of TD.88137 continue to evolve and include atherosclerosis, obesity, non-alcoholic steatohepatitis (NASH), osteoporosis,
hypertension and metabolic syndrome. Contact us for a more extensive reference list.

Amino acid defined | Envigo
Formula examples:
- TD.99366 Amino acid diet
- TD.90262 Methionine and choline deficient diet
- TD.00434 Folic acid deficient diet
- TD.99386 No lysine AA diet
Sometimes this type of diet is used to further reduce the background level of certain vitamins that are found in protein sources such as casein or vitamin-free (alcohol extracted) casein. Some folic acid deficient diets utilize this approach.
The amino acid profile for most amino acid defined diets is based on work by Harper and Rogers (J. Nutr. (1965) 87:267-276) and is not representative of the amino acid profile of an intact protein source such as casein. Other amino acid profiles can be specified. When an amino acid(s) is removed or reduced, isonitrogenous adjustment can be made if required.

You may want to prepare your own diet at your research site or facility, and if that is the case, you depend on the ingredients being of the highest quality. Envigo can provide you with many of the same ingredients used to produce our advanced Teklad custom research diets so you can develop your own formula. And as always, our nutritional experts are here to help you make the best decisions for your ingredients and ultimate formulation.
Our ingredients
We offer several ingredients for individual sale so that you can develop your own blends.
“VFT” casein
- “Vitamin-free” test casein (alcohol-extracted) is best suited for purified test diet formulas where fat or vitamin content needs to be precisely controlled
- The reduced levels of many vitamins in VFT casein make it the preferred protein source for many vitamin studies. Thus, the nickname “Vitamin-free” was given to the extracted casein many years ago
Vitamin mixes
- The common vitamin mixes shown below use sucrose or corn starch as a carrier
- Customized vitamin mixes may use cellulose if a non-nutritive carrier is necessary
- Vitamin mixes are formulated with a diet inclusion rate in mind. Using more or less than recommended could impair the health of your laboratory animal
- For those preparing their own diets, vitamin premixes are an efficient way to add vitamins to a diet
- Vitamin mixes should be stored at 4 degrees celsius or lower upon receipt. Storage at –20 degrees celsius is recommended if the mix will be used beyond 1 month
- Minimum order is 500 g for both stock and custom vitamin mixes
- Our available vitamin mixes are commonly used in diets, and are available from stock
- Vitamin mixes are shipped within a few days of order
Our Formula examples
- CA.40060 Teklad vitamin mix
- CA.40077 AIN-76A vitamin mix

Mineral mixes
- The common mineral mixes shown below as examples use sucrose as a carrier
- Customized mineral mixes could use cellulose or no carrier if a non-nutritive carrier is necessary
- Our mineral mixes are formulated with a diet inclusion rate in mind. Using more or less than recommended could impair the health of the animal
- For those preparing their own diets, mineral premixes are an efficient way to add minerals to a diet

Diets for diet-induced obesity (DIO)
Diets with 55-60% of calories from fat like TD.06414 and TD.93075 are commonly used for inducing obesity in rodents. While considered extreme compared to typical human fat consumption, these diets are effective in initiating rapid weight gain in most rodents. With higher fat content there is less room for carbohydrate, thus the carbohydrate (particularly sucrose) amount is relatively low compared to other obesity inducing diets. If you are interested in high fat and high carbohydrate, look at diets with 40-45% of calories from fat (often referred to as western diets).
As the fat level increases, pellet quality (durability) is often compromised. Some higher fat formulas are available only in non-pelleted form or require specific carbohydrate, maltodextrin, for pelleting. Depending on the fat and carbohydrate sources used, the non-pelleted form could be dense and crumbly, dough-like, or paste-like. Though a little more challenging to work with, non-pelleted diet is still used by many researchers for diet-induced obesity models as these researchers suspect the softer form may enhance obesity development.
Diets with 40-45% of calories from fat, like TD.95217, TD.88137, TD.06415, and TD.08811, represent another popular diet pattern for diet-induced obesity work. These diets have double or triple the amount of sucrose found in higher fat diets. High levels of simple carbohydrate like sucrose and fructose may help to promote hypertriglyceridemia, insulin resistance, and fatty liver. Diets with a pattern of high sucrose and high saturated or trans fat are often referred to as “Western Diets” in obesity and cardiovascular fields. Some “Western Diets” have further modifications to the fatty acid profile or even specific vitamin and minerals adjustments to be even more closely matched to a Western Diet pattern. For specific fatty acid modifications, see examples on our fat/lipid adjusted diets page.
Diets for diet-induced diabetes
Many of the same diets used for inducing obesity in rodents can be used to enhance diabetes related phenotypes like insulin resistance and glucose intolerance. However, fasting hyperglycemia characteristic of diabetes (glucose > 200 mg/dL) is uncommon with a diet only approach. Pre-feeding a high fat diet to induce a certain level of obesity and insulin resistance and then giving low-dose streptozotocin (STZ) may be an effective approach if overt hyperglycemia is desired.
Ingredient matched, low-fat DIO control diets
There are many options with different levels and types of fat in addition to different types of carbohydrate ranging from sucrose (highly refined, simple digestion) to corn starch (refined, but more complex) to resistant starch (refined, but not fully digestible). A very basic purified control diet would be AIN-93M (TD.94048) or AIN-93G (TD.94045). AIN-93 diets have a moderate amount of sucrose at ~10%, and fat is from soybean oil with a healthy fatty acid profile. Additional examples of controls for specific DIO diets can be found in the above tables.
Many researchers choose to compare their high fat fed animals to animals fed a natural ingredient, grain-based diet (also referred to as standard diets or chow). These diets differ in the source and level of nutrients as well as in the presence of non-nutritive factors (such as phytates or phytoestrogens). Depending on what your main comparisons are, it may be suitable to have a grain-based diet as your control/reference group. However, making such comparisons limits inferences to dietary patterns versus a specific dietary component.
