检测方法 SDS-PAGE SEC-HPLC ELISA SPR

生物特性参数 蛋白类型重组人白介素-31（His标签） 种属来源人 生物活性描述EC50 of 1.53μg/ml determined by ELISA; affinity constant of 125.61 nM determined in SPR assay. 应用瘙痒相关皮肤病研究，如大疱性类天疱疮、银屑病、慢性荨麻疹等 产品别称Interleukin-31;IL-31;IL31

样本类型 重组蛋白

技术参数纯度> 95% as determined by SDS-PAGE and SEC-HPLC 内毒素水平Less than 1 EU per μg by the LAL method. 分子量The protein has a predicted MW of 16.9 kDa. Due to glycosylation the protein migrates to 20-25 kDa based on Bis-Tris PAGE result. 制剂形式Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. 活性EC50 of 1.53μg/ml determined by ELISA; affinity constant of 125.61 nM determined in SPR assay. 储存条件-25~-15℃保存，收到货之日起，有效期1年。复溶后， -85~-65℃保存，3个月有效期。避免反复冻融。 表达序列Ser24-Thr164 表达系统HEK293 标签N-His 外观Lyophilized Powder 复溶方法用蒸馏水溶解冻干的蛋白。如果规格为25μg或者100μg，建议复溶到0.5mg/mL的浓度。对于500μg或1mg的冻干粉，建议以1mg/mL的浓度复溶。复溶过程中请不要剧烈涡旋或者剧烈摇晃。将复溶后的蛋白溶液按照需求进行分装，储存于至-80℃，避免反复冻融。 AccessionQ6EBC2-1
