Indolicidin is an antimicrobial peptide.1 It is active against multidrug-resistant isolates of enteroaggregative E. coli (MDR-EAEC; MICs = 32 ?M for all). Indolicidin is also active against S. cerevisiae, T. beigelii, and C. albicans (MICs = 5-10, 2.5-5, and 5-10 ?M, respectively) and reduces viral replication of HIV-1 in MT-2 cells when used at concentrations ranging from 67 to 100 ?g/ml.2,3 In vivo, indolicidin increases survival of MDR-EAEC-infected G. mellonella larvae.1

Cell experiment: | The time course and dose dependence of indolicidin bactericidal activity are determined using Escherichia coli ML35 and Staphylococcus aureus 502A as test organisms. The assays are performed in 10 mM sodium phosphate buffer, pH 7.4, at 37°C. A 50 μg sample of indolicidin is dissolved in 50 pl of 0.1 M pyridine acetate, pH 6.5, and incubated with 5 μg of chymotrypsin for 15 h at 37°C. Digestion of the sample is confirmed by the disappearance of the indolicidin band on acid-urea PAGE. Following lyophilization, untreated and digested samples are tested for antibacterial activity in a agar diffusion assay against Escherichia coli using concentrations of peptide ranging from 10 to 300 μg/mL[1]. |

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
