Abstract: | Based on current research, there are three technologies during the test of bacterial endotoxin of liposomes: (1) extraction of bacterial endotoxin from liposomes; (2) addition of bacterial endotoxin in the process of recovery test; and (3) elimination of the interference factors from drugs and excipients. In the present study, we pointed out that the key technologies to test bacterial endotoxin from paclitaxel liposome included following steps: extraction of bacterial endotoxins from ethanol-dissolved liposomes; preparation of positive control of recovery solution by adding 0.01 mL standard endotoxins in 1 mL liposome ethanol solution; and the use of 0.5% human albumin to eliminate the interference from detection, and accurate detection of the bacterial endotoxin of liposomes. |
