A process for preparing a polysarcosine modified allergen comprises binding polysarcosine in the form of a compound of formula (I):
wherein R is a C1-6 alkyl group, preferably methyl, n is 1 or 2, B is a hydrocarbon chain of 1 to 4 carbon atoms, optionally containing a double bond, and the polysarcosine is bound through its N-terminus; to an allergen. The modified allergen thus produced is useful in suppressing the production of IgE antibodies specific to unmodified allergen.
制备改性聚肌氨酸过敏原的工艺包括以式(I)化合物的形式结合聚肌氨酸:
其中 R 是 C1-6 烷基,最好是甲基,n 是 1 或 2,B 是 1 至 4 个碳原子的烃链,可选含有双键,多肌氨酸通过其 N 端与过敏原结合。由此产生的改性过敏原可抑制未改性过敏原特异性 IgE 抗体的产生。
