Embodiment 1
[0039] Utilize film dispersion method to prepare polypeptide liposome, step:
[0040] Step 1: Accurately weigh 300mg of soybean lecithin, 100mg of cholesterol, and 10mg of polypeptide into a 500ml round bottom flask, and dissolve in 60ml of chloroform / methanol mixed solvent with a volume ratio of 2:1.
[0041] Step 2: Add 25 glass beads, rotate under reduced pressure on a 40°C water bath to form a thin film, take 20ml of PBS buffer, heat to 55°C, pour into a flask, and stir in a 55°C water bath for 30 minutes to hydrate the lipid film fall off.
[0042] Step 3: pass through a 450nm microporous membrane to obtain a liposome suspension, freeze and dry to obtain a dry polypeptide liposome powder.
Embodiment 2
