ENZO 年销售排名第一

      治疗性单克隆抗体在纯化过程中，A蛋白能够从柱子中浸出，从而导致污染。而在单抗药物中，残余的蛋白质A能够引起病人细胞促有丝分裂或免疫反应。因此，食品及药物管理局（FDA） 严格规定了治疗性药物单克隆抗体A蛋白质可接受的水平。

      Enzo 推出的Protein A ELISA Kit，可以快速有效地检测治疗性单克隆抗体中金黄色葡萄球菌细胞壁A蛋白残留，得到业界普遍认可，Protein A ELISA Kit在ENZO销售产品中，名列第一。

Fig 1. Protein A Standard Curve. A) AlphaLISA Protein A Assay. A 12-point dilution series of the positive control was prepared ranging from 100,000 - 0.3 pg/mL was prepared. Twelve background points were used to calculate LDL. B) Protein A ELISA Assay. A 9-point dilution series of the positive control was prepared ranging from 100,000 – 10 pg/mL. Twelve background points were used to calculate LDL

样品处理要求：

稀释样品保证总IgG浓度≤ 1 mg/mL
