Cell experiment: | Sphistin Synthetic Peptide (12-38) is diluted to final concentrations from 1.5 mM to 96 mM with Milli-Q sterilized water.The microorganisms are diluted with 10 mM phosphate buffer (PBS, pH 7.4) to 3.3×104 cfu/mL and incubated with serial dilutions of truncated peptides. Samples without peptides are considered as blanks. After 20 h (40 h for yeast) of incubation at 30 C, the MIC at which the lowest concentration of peptide inhibiting growth of the organisms is determined. Then the cultures are plated on appropriate agar and the minimum bactericidal concentration (MBC) value, which is the least concentration showing no bacterial growth after incubation at room temperature for 24-48 h, is recorded. All the values are averaged using three independent measurements[1]. |

Sphistin Synthetic Peptide (12-38, Fitc in N-Terminal-Fluorescently Labeled Peptide) is a truncated fragments of Sphistin Synthetic Peptide that shows potent antimicrobial activity.
Sphistin is a synthetic 38-amino acid H2A derived peptide from Scylla paramamosain. Sphistin Synthetic Peptide (12-38) shows a stronger activity with a much lower minimum inhibitory concentration (3 mM) against Staphylococcus aureus, Corynebacterium glutamicum, Micrococcus lysodeikticus Fleming, Bacillus subtilis, Pseudomonas fluorescens, Aeromonas hydrophila and A. sobria in comparison with the reported Sphistin. A leakage of intracellular content is described in E. coli treated with Sphistin Synthetic Peptide (12-38). Unlike Sphistin which mainly disrupts the membrane integrity, Sphistin Synthetic Peptide (12-38) could also combine the A. sobria genomic DNA with a minimum concentration of 6 mM and is located intracellularly in cells observed under confocal laser scanning microscope imaging[1].
In comparison with the control group of Oryzias melastigma injected with A. sobria alone, the group treated with a mixture of Synthetic Peptide (12-38) and A. sobria shows a higher survival rate 7 days post-injection. Furthermore, in a pretreatment assay at 6 h, a higher survival rate is observed in the group injected with the mixture of Synthetic Peptide (12-38) and A. sobria[1].

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
