Figure 8. . Stability of freeze-dried vasoactive intestinal peptide in sterically stabilized micelles nanomedicine capsules.

(A) Comparison of percentage of full-length VIP released from capsules containing VIP-SSM nanomedicine (blue) and VIP released from capsules filled with a commercially used diluent filler: lactose (purple). (B) Release profiles of VIP-SSM capsules stored in airtight glass containers at 4°C up to 6 weeks. VIP EIA was used to determine release of full-length VIP peptide. Data points are the average of at least three independent experiments ± SEM.

EIA: Enzyme immuno assay; VIP-SSM: Vasoactive intestinal peptide in sterically stabilized micelles.
