Description

Benzylpenicilloylformyllysine is a key chemical derivative and hapten-protein conjugate used in advanced immunological research and diagnostics. This compound is critical for studying penicillin allergy, serving as a model antigen to detect and quantify specific IgE antibodies. It is primarily utilized by pharmaceutical R&D laboratories, diagnostic kit manufacturers, and academic institutions focused on immunology and hypersensitivity reactions. Our supply ensures high purity and batch-to-batch consistency for reliable experimental and diagnostic outcomes.

Application

• Penicillin Allergy Diagnostics: As a critical hapten for in vitro assays to detect and measure IgE antibodies specific to the benzylpenicilloyl (BPO) determinant.
• Immunological Research: Used as a model antigen in studies of drug hypersensitivity mechanisms, immune response profiling, and epitope mapping.
• Diagnostic Kit Manufacturing: A key raw material in the production of enzyme-linked immunosorbent assay (ELISA) and radioallergosorbent test (RAST) kits for drug allergy testing.
• Reference Standard: Serves as a certified reference material (CRM) for method validation and quality control in clinical and research laboratories.
• Bioconjugation Studies: Employed in developing and optimizing protein-hapten conjugation techniques for vaccine and therapeutic antibody research.

Quality Control

Every batch of Benzylpenicilloylformyllysine is produced and tested under a strict quality management system. We ensure compliance with high-purity standards suitable for research and in vitro diagnostic use. Comprehensive analytical testing, including HPLC for purity and identity confirmation, is performed. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, assay, and related substances.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a desiccated environment to maintain stability and purity. For long-term storage, consider storing under an inert atmosphere.
