| Description | Gramicidin S 2HCl, is an antibiotic. At concentrations of 40-80 μg/mL, GS can reduce planktonic cell numbers within 20-40 minutes. For established biofilms, it effectively kills cells at concentrations of 100-200 μg/mL without regrowth. This anti-biofilm effect results from peptide transmembrane transport and complexation with intracellular nucleotides (including the alarmone ppGpp). GS demonstrates wide-ranging activity against biofilm-forming, drug-resistant infections caused by E. faecalis, proving its efficacy in endodontic treatment. The successful treatment of persistent infections in two volunteer cases further confirms GS's potent therapeutic performance. These studies indicate that GS can be applied in certifying compounds used in endodontics. |

For example, if the dosage of your experiment is 10mg/kg, the weight of each animal is 50g, and the volume of the dosing is 100μL, then the working solution concentration of your experiment is 5mg/mL. If the formula you used is 5% DMSO+ 30% PEG300+ 5% Tween 80 + 60% Saline/PBS/ddH2O, the preparation method is as follows:
Mother liquor preparation method: 5mg of drug dissolved in 100μL DMSO (mother liquor concentration is 50mg/mL). Preparation method of in vivo formulation: For 1mL of working solution preparation, take 50μL of DMSO mother liquor, add 300 μL of PEG300 to mix well and clarify, then add 50μL of Tween-80 to mix well and clarify, and finally add 600μL of Saline/PBS/ddH2O to mix well and clarify.Note:
- For Reference Only. Please choose the appropriate dissolution protocol according to your experimental animal and administration method.
- We suggest that in cell experiments, the final concentration of DMSO is not more than 0.1%, in animal experiments, for healthy mice, the final concentration of DMSO is not more than 10%; For nude or frail mice, the final concentration of DMSO is not more than 2%.
