Tamoxifen diets
Diets with tamoxifen activate CreER
Several references cite use of tamoxifen-containing diets for models with Cre under the control of a mutated estrogen receptor. Envigo Teklad diets makes a variety of tamoxifen-containing diets customized to meet your research needs. We also make a variety of doxycycline-containing diets for tet regulated systems. If you have any questions, don’t hesitate to consult a nutritionist.
Teklad stocks tamoxifen and tamoxifen citrate
Tamoxifen is added to the diet as a tamoxifen-sucrose mixture. Users are encouraged to use the stocked supply. However, Teklad will continue to work with customer prepared mixes. If you choose this option, please consult a nutritionist for additional information about preparing and sending the mixture.
Users are encouraged to select from the stocked options below supply readily available to ship within days.
Users are encouraged to select from the stocked options below supply readily available to ship within days.
1 Assumes 20-25 g body weight and three-four g intake
2 Tamoxifen citrate is 66% tamoxifen
3 Referred to as TAM400/CreER in Europe (TD.55125)
Please add 5-10 day lead time for irradiated diets; minimum 3 kg orders are required for stocked and customized items.
These diets all have tamoxifen premixed with ~five percent sucrose as a palatability enhancer; however, feed aversion may still occur. If intake is a problem, see below for advice.
Teklad Global 2016 — base diet in these examples — is only one of several minimal phytoestrogen diets Teklad produces. Consult a nutritionist about use of other base diets.

COLLAPSE ALL TABS
- Minimum order quantity is three kg, sufficient for feeding ~20 mice for one month
- Store diet refrigerated and plan to use within six months
- Typical lead time is two weeks (four weeks if irradiated)
- Irradiation (optional) minimal dose of 20 kGy (Must be requested at time of order)
- To place an order: contact Teklad Customer Service at 800.483.5523 or initiate order online
Plan for:
- Initial reduction in food intake and weight loss
- Daily observation of animal tolerance — consult your IACUC for monitoring metrics
- Intervene when necessary
If intake seems to be a problem:
- Determine if a lower dose is effective for your model by conducting a tamoxifen dose feeding trial
- Gradually acclimate mice by mixing tamoxifen-containing pellets with regular feed pellets
- Wet the food, then place in a dish inside the cage (requires daily replacement)
- Feed tamoxifen diet on weekdays, regular diet on weekends
- Alternate weeks (two weeks on tamoxifen diet, one week off) for longer treatments
- Tamoxifen is a selective estrogen receptor modulator (SERM) meaning it can repress actions of estrogen or have pro-estrogen effects
- Usual dose for therapeutic effects in humans is 20 mg/day. Tamoxifen diets for rodents typically contain ~one to two mg/pellet
- Accidental tamoxifen exposure can be minimized by using typical lab precautions of lab coat, gloves, and mask when handling the diet.
- Your chemical safety department should be contacted for additional institution specific guidelines for handling and disposal of tamoxifen containing diets.
- Length of treatment varies from one to two weeks1,2,5,6,7,8 to one to two months3,4,8
- Pure tamoxifen1,5,8 and tamoxifen citrate1,2,3,4,6,7 are both effective
- Usual tamoxifen doses are ~40-80 mg per kg body weight per day
- Typical inclusion for pure tamoxifen is 250 mg8 or 500 mg1,5 and for tamoxifen citrate is 400 mg per kg diet1,2,3,4,6,7
- Initial weight loss of ten % is reported1,2,4,7,8, associated with reduced food intake2
- Subsequent recovery of body weight after returning to regular diet may be compromised by gene inactivation2,7
