Streptothricin F
Based on 1 Customer Validation
Streptothricin F is a bactericidal antibiotic. Streptothricin F interacts with the 30S subunit of 70S ribosome. Streptothricin F shows rapid, bactericidal activity against highly drug-resistant, carbapenem-resistant Enterobacterales (CRE) (MIC50 and MIC90: 2 and 4 μM, respectively) and Acinetobacter baumannii.

Bacterial live/dead nucleic-acid viability staining
The LIVE/DEAD bacterial viability staining method is based on differential permeability of nucleic-acid-binding fluorescent dyes, most commonly SYTO 9 and propidium iodide (PI), which enables discrimination of bacterial populations with intact versus compromised cytoplasmic membranes. SYTO 9 penetrates both intact and damaged bacterial membranes and binds nucleic acids to produce green fluorescence, whereas propidium iodide penetrates only cells with compromised membranes and fluoresces red while also reducing SYTO 9 signal through competitive binding and fluorescence interactions. The resulting fluorescence pattern is interpreted as a proxy for membrane integrity, which is widely used as an indicator of bacterial viability in microscopy, flow cytometry, and spectroscopic platforms. However, mechanistic studies show that SYTO 9 and PI interactions involve displacement and fluorescence resonance energy transfer effects, which can influence signal interpretation depending on dye ratios a
