  • 80®: Tween 80®), and 90% deionized water. The organic phase, composed of bocaiúva oil and surfactants, was stirred at 400 rpm at 35 °C for 20 min. The aqueous phase (deionized water with conductivity below 0.4 μS and pH 6.5) was added to the organic phase at 1 mL/min under continuous magnetic
  • to each well [41]. The plates were incubated for 1 h at 37 °C and were centrifuged at 3000 rpm at 5 °C for 15 min. After centrifugation, the concentration was suspended in 50 mL of phosphate-buffered saline (PBS, pH 7.4). The amount of hemoglobin was determined at 540 nm using a docetaxel (DTX) 880
