其他資料

Fel d 1（Felis domesticus allergen 1^[2]）是貓的一種蛋白質，由CH2基因編碼^[3]^[4]。Fel d 1主要在貓的唾液腺和皮脂腺中分泌，是存在於貓身上的主要過敏原。目前尚未清楚這種蛋白質在動物體內的作用，但它能引起敏感人群對lgG或lgE作出過敏反應或哮喘反應。

降低家居Fed d 1含量的可行方法有移開柔軟表面（地毯）、經常洗床單、洗高效濾網和為貓洗澡。Fel d 1是一種特別粘的蛋白質，已被證明能粘在衣物和人的毛髮中，而且在貓從未出現過的地方也能檢測得到。

貓平均每天產生2-7微克的Fel d 1。研究也發現未被閹割的公貓的Fel d 1的產量較被閹割的公貓多，這也導致一個假設的產生，假設認為Fel d 1是由睾酮激素調控的。被閹割的公貓的Fed d 1產量和母貓相近，而未被閹割的母貓的Fel d 1的產量也與被閹割的母貓的相近。儘管母貓和被閹割的公貓的Fel d 1產量低，但也足以引發敏感人群的過敏反應。

Fel d 1是一種分子量有18 kDa的異源二聚體蛋白質^[2]。
