BD 221341 - BBL Difco Salmonella D Antigen Quality Control 1mL Reliable QC Reagent for Serological Validation and Salmonella Typing, EA

The BD 221341 BBL Difco Salmonella D Antigen Quality Control 1mL is a high-quality reference reagent designed to verify the performance and accuracy of Salmonella serological testing procedures. This reagent contains standardized Salmonella D antigen suspension prepared for quality control use in laboratories performing serotyping according to the KauffmannWhite scheme. Manufactured with BDs strict production controls, this QC antigen provides consistent and reproducible reactivity, allowing laboratories to validate antisera activity, ensure reliable agglutination results, and maintain compliance with microbiological testing standards.

Key Benefits

The BD 221341 Salmonella D Antigen QC reagent offers dependable and precise results in serological testing. Each vial is standardized for optimal antigen concentration to produce consistent agglutination reactions with corresponding Salmonella O and H antisera. Its high specificity supports accurate quality control of Salmonella typing reagents and testing workflows. The ready-to-use 1mL format minimizes preparation time and error, while BDs high production standards ensure reagent stability, long shelf life, and consistent performance across batches.

Compatibility and Applications

This QC reagent is compatible with BD BBL and Difco Salmonella antisera and other standard diagnostic antisera used for identifying Salmonella serogroups and serotypes. It is primarily used for routine quality control validation in microbiology laboratories that perform serological identification of Salmonella species in clinical, food safety, or environmental testing. The BD 221341 QC Antigen serves as a benchmark control for ensuring the reliability of reagents and methods used in Salmonella O (somatic) antigen detection.

Usage Guidelines

Use the BD 221341 Salmonella D Antigen QC 1mL reagent according to your laboratorys quality control protocols and BDs product instructions. Shake gently before use to resuspend any settled antigen. Mix one drop of the QC antigen with a drop of the corresponding Salmonella antisera on a clean glass slide and observe for agglutination within one minute. A positive control reaction confirms antisera potency and procedural accuracy. Store the vial at 28C, avoid freezing, and protect from light. Discard if the reagent shows discoloration or loss of expected reactivity.

Certifications, Safety Standards, and Regulatory Approvals

The BD 221341 BBL Difco Salmonella D Antigen QC reagent is manufactured under ISO 13485 and ISO 9001 certified quality management systems. It meets FDA and CE requirements for in vitro diagnostic (IVD) use and conforms to Good Manufacturing Practice (GMP) standards. Each lot undergoes rigorous validation for specificity, potency, and sterility, ensuring consistent and reliable performance for laboratory quality control.

Comparison with Competitor Products

Compared to competitor QC reagents, the BD 221341 Salmonella D Antigen QC offers superior stability, specificity, and reproducibility. While other brands may show variable agglutination strength or shorter shelf life, BDs precise formulation ensures consistent reactions and predictable QC results. Laboratories worldwide rely on BDs Salmonella QC reagents for maintaining traceability and compliance with international testing protocols such as ISO 6579 and WHO reference methods.

Typical User Profile and Application Scenarios

The BD 221341 BBL Difco Salmonella D Antigen QC 1mL is intended for use by microbiologists, laboratory technologists, and quality assurance professionals working in clinical diagnostic, food microbiology, and public health laboratories. Typical applications include verifying antisera reactivity, validating test batches, and serving as a positive control for routine Salmonella serogrouping and identification assays.

Best Practices for Use and Maintenance

For consistent results, always handle the reagent using aseptic techniques. Allow refrigerated vials to equilibrate to room temperature before use to ensure optimal reactivity. Do not dilute the reagent, and use clean slides or microtiter wells for each test. Regularly verify control reactions against reference antisera to confirm assay performance. Discard expired or contaminated reagents and store unused vials upright at 28C, protected from direct light exposure.

Regulatory and Safety Information

The BD 221341 BBL Difco Salmonella D Antigen QC reagent is intended for in vitro diagnostic use only and should be handled by trained laboratory personnel. It is non-toxic but may contain trace preservatives. Avoid ingestion or contact with skin and eyes. Always wear appropriate personal protective equipment (PPE), including gloves and lab coats, and follow institutional biosafety guidelines for handling biological reagents. Dispose of used materials as biohazard waste according to local regulations.
