Recombinant Cat Allergen Fel d 4 Protein，His & SUMO

Fel d 4 is a major allergen derived from domestic cats, belonging to the lipocalin protein family. It is known to be a significant trigger for allergic reactions in sensitized individuals, contributing to symptoms such as asthma, rhinitis, and conjunctivitis. The prevalence of cat allergies has been rising, affecting millions of people worldwide and resulting in a significant public health concern. Research into Fel d 4 is crucial, as it provides insights into the molecular mechanisms of allergic responses and can facilitate the development of targeted immunotherapies. Recombinant Fel d 4 protein has been produced to study its structure, function, and allergenic properties in a controlled environment, allowing for the advancement of allergen-specific therapies. This approach aims to reduce sensitivity in allergic individuals and improve their quality of life. Additionally, understanding the potential cross-reactivity of Fel d 4 with other allergens may help in developing broader strategies for managing allergies. The ongoing research into Fel d 4's role in allergic mechanisms is essential for designing effective interventions and treatments for cat allergies, potentially leading to new avenues in allergy management.
