简介：
Overview
This protocol describes a method for the removal of endogenous lipids from allergens and their replacement with user-specified ligands. The approach utilizes reverse-phase HPLC coupled with thermal annealing, allowing for the study of allergen structure and immunogenicity.
Key Study Components
Area of Science
- Allergen research
- Biochemistry
- Immunology
Background
- Allergens often bind hydrophobic molecules that can influence their structure and function.
- Understanding the factors contributing to allergenicity is crucial for therapeutic design.
- Endogenous ligands can obscure binding sites, complicating studies of allergen behavior.
- Reverse-phase HPLC is a technique that can effectively remove these ligands.
Purpose of Study
