生物特性参数 蛋白类型重组蛋白 种属来源人 生物活性描述ELISA检测显示，与人FcεRIα结合的EC50为1.5 ng/ml；与Omalizumab结合的EC50为5.1 ng/ml。

样本类型 重组蛋白

技术参数纯度>90% as determined by SDS-PAGE and HPLC 内毒素水平<1.0 EU per μg by the LAL method 分子量The protein has a predicted MW of 26.18 kDa. Due to glycosylation the protein migrates to 35-40 kDa based on Bis-Tris PAGE result. 制剂形式Lyophilized from 0.22μm filtered solution in 20mM PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. 储存条件-25~-15℃保存，收到货之后有效期1年。复溶后，无菌条件下，-85~-65℃保存，3个月有效期。 表达序列Cys209-Lys428 标签C-His 表达系统HEK293 外观Lyophilized Powder 复溶方法开盖之前，先离心。使用蒸馏水复溶冻干的蛋白质，复溶浓度超过100 μg/mL。建议首次使用时将蛋白分装为每次实验用量，避免反复冻融。 蛋白登录号P01854 产品别称IgE Ig epsilon chain C region
