Description

Rice Major Allergenic Protein CAS NO 147097-22-1 is a purified protein fraction derived from rice (*Oryza sativa*), specifically isolated to contain its principal allergenic components. This reference standard is critical for food safety research, enabling the accurate detection and quantification of rice allergens in food products and environmental samples. It is an essential material for diagnostic kit manufacturers, food testing laboratories, and research institutions focused on allergenicity studies, immunological assays, and the development of hypoallergenic food products.

Application

• Reference Standard for Immunoassays: Serves as the primary calibrant and positive control in ELISA (Enzyme-Linked Immunosorbent Assay) and lateral flow test kits designed to detect rice allergens.
• Food Safety & Quality Control: Used by food manufacturers and third-party labs to validate "free-from" claims (e.g., gluten-free, allergen-free) and for cross-contamination monitoring in production facilities.
• Allergenicity & Biomedical Research: Fundamental for studying the immune response to rice proteins, mapping IgE-binding epitopes, and investigating cross-reactivity with other grain allergens.
• Diagnostic Reagent Development: A key component in the development and lot-to-lot validation of in-vitro diagnostic (IVD) reagents and clinical tests for specific IgE detection.
• Product Development for Hypoallergenic Foods: Used as a benchmark to test the efficacy of processing methods aimed at reducing or eliminating allergenic potential in rice-based ingredients.
• Regulatory Compliance & Method Validation: Supports laboratories in validating analytical methods to meet global food labeling regulations (e.g., FDA, EU, Codex Alimentarius).

Quality Control

Our Rice Major Allergenic Protein is produced and handled under strict quality protocols to ensure batch-to-batch consistency and reliability for critical research and diagnostic applications. Each lot is characterized for protein content and allergenic activity. A comprehensive Certificate of Analysis (COA) is provided, detailing specifications such as purity (by HPLC), protein concentration, and immunological reactivity. Our quality system supports compliance with relevant standards for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This material is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For extended storage, consider under an inert atmosphere.
