Key Benefits
BDs Voges-Proskauer B Reagent offers reliable color development, delivering clear and interpretable results when used in the VP metabolic pathway test. The single-use dropper format eliminates reagent waste and reduces contamination risk. Its qualitative formulation ensures fast, predictable reaction outcomes and excellent reproducibility across laboratories. BDs stringent manufacturing standards guarantee consistent performance with every lot, supporting accurate organism identification.
Compatibility and Applications
This reagent is intended for use with the classic VP test and is compatible with a wide variety of bacterial isolates, including:
- Enterobacter species
- Klebsiella species
- Serratia species
- Other acetoin-producing Gram-negative bacteria
Primary applications include:
- Differentiating VP-positive from VP-negative organisms
- Clinical organism identification in diagnostic laboratories
- Quality-control workflows in biochemical testing panels
- Educational labs teaching microbial metabolic pathways
Usage Guidelines
After incubating the bacterial broth culture, add VP Reagent A followed by BD Voges-Proskauer B Reagent. Gently mix and allow the reaction to develop for the recommended time. A pink to red color indicates a positive VP reaction, confirming acetoin production. Use proper timing and follow kit instructions for optimal accuracy. Store ampules at controlled room temperature and avoid exposure to excessive heat or light.
Certifications, Safety Standards, and Regulatory Approvals
BD 261193 is manufactured under ISO 9001 and ISO 13485 certified quality systems, meeting FDA and CE requirements for in vitro diagnostic (IVD) reagents. Each lot undergoes rigorous testing for sterility, chemical integrity, stability, and performance accuracy to ensure consistent VP reaction reliability.
Comparison with Competitor Products
Compared to bulk VP reagents, BDs single-use dropper ampules offer more reliable reagent stability, improved accuracy, and reduced contamination risk. Competitor formulations may show inconsistent reactivity or require manual dispensing steps that increase variability. BDs ready-to-use dropper packaging ensures consistent volume delivery and better workflow efficiency.
Typical User Profile and Application Scenarios
This reagent is ideal for clinical microbiologists, diagnostic technologists, research scientists, and teaching laboratories. It is typically used in:
- Routine identification of Enterobacterales
- Metabolic profiling workflows
- Quality-controlled biochemical testing panels
- Educational demonstrations of fermentation pathways
Best Practices for Use and Maintenance
Use aseptic technique when opening dropper ampules. Expel the full contents to ensure proper reaction volume. Always compare results with known VP-positive and VP-negative controls. Do not reuse or store opened ampules. Dispose of used reagents and contaminated cultures as biohazard waste. Regularly check expiration dates to maintain testing accuracy.
Regulatory and Safety Information
The BD 261193 Voges-Proskauer B Reagent is intended for in vitro diagnostic use by trained personnel. Handle all bacterial cultures according to biosafety level 2 guidelines. Wear appropriate PPE including gloves, eye protection, and lab coat. Dispose of chemical and biological waste according to institutional and regulatory requirements.
