Fig. 5From: C-terminal mini-PEGylation of a marine peptide N6 had potent antibacterial and anti-inflammatory properties against Escherichia coli and Salmonella strains in vitro and in vivoBiodistribution of N6 and N6-COOH-miniPEG in the healthy nude mice. The nude mice were injected intraperitoneally with 10Â mg/kg FITC-labeled N6, N6-COOH-miniPEG or free FITC, and fluorescence (ventral) was observed at 10, 30, 45, 60, 90, 120, 180, 240, 360, and 1440Â min, respectively. The mice from left to right were free FITC, FITC-labeled N6, FITC-labeled N6-COOH-miniPEG, and the blank control, respectivelyBack to article page
