SOP

Materials

  • Tween 80 - Sigma P1754
  • PEG 400 Liquid - Sigma P3265

Preparation

  • Weigh out 2.08g of each Tween 80 and PEG into a 50 mL falcon tube. Bring up to 40 mL with water and filter by steriflip. This is 5.2% PEG/Tween
  • Dissolve rapamycin at 20 mg/mL (0.0219 M) in ethanol (prepare as a 1 mL aliquot and store at -20 C).
  • Add 5 uL of 20 mg/mL RAPA in 1 mL Tween 80/PEG diluent to get a 0.1 mg/mL concentration (109 uM; use this for 1 week).
  • IP inject 10 uL/g body weight (1 mg/kg)

Alternate Rapamycin Injection Regimen

rapamycin treatment was performed by injecting 8 to 10 week old mice intraperitoneally once daily with either 1 mg/kg rapamycin suspended in 0.9% NaCl and 2% ethanol at a concentration of 0.5 mg/mL (547 μM), or vehicle only for 14-28 days.
