This video demonstrates the production of nanoemulsion tumor vaccines. The stable oil reservoir depots carrying synthetic peptides and adjuvants are produced by low-energy nanoemulsion, offering significant promise for tumor immunotherapy.
Protocol
1. Preparation of the I-OVA NE Admix 1 mg of monophosphoryl lipid A (MPLA) with 100 µL of dimethyl sulfoxide (DMSO), vortex for 5 min, and allow it to stand for 4 h at room temperature (RT) to dissolve completely. Add Tween 80 and IKVAV-OVA257-264 (I-OVA) quantitatively and mix. NOTE: Tween 80 and I-OVA were mixed at a mass ratio of 25:1. Add squalene into the mixture prepared in …
