Description

Penicilloyl Polylysine is a synthetic, well-defined hapten-protein conjugate used as a critical reagent in immunological and diagnostic applications. Its primary value lies in its role as a standardized antigen for the detection of penicillin-specific IgE antibodies, which is essential for allergy testing and research. This product is vital for manufacturers of in-vitro diagnostic (IVD) kits, clinical research organizations, and pharmaceutical companies involved in drug safety and immunogenicity studies.

Application

• In-Vitro Diagnostic (IVD) Reagent: A key component in immunoassays and test kits for the specific and sensitive detection of penicillin allergy.
• Immunological Research: Used as a model hapten-carrier complex to study immune responses, antibody formation, and hypersensitivity mechanisms.
• Pharmaceutical Safety Testing: Employed in assays to assess the potential immunogenicity of β-lactam antibiotics and related compounds during drug development.
• Clinical Laboratory Testing: Serves as a reference standard or calibrator in laboratory-developed tests (LDTs) for penicillin allergy diagnosis.
• Allergen Standardization: Acts as a defined antigen source for the standardization and quality control of allergy testing procedures.
• Bioconjugation Studies: Used as a reference compound in developing and validating methods for coupling small molecules to carrier proteins.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a desiccated environment to maintain stability. For long-term storage, consider freezing at -20°C under desiccant.
