艾美捷科技代理Worthington品牌。

Worthington Biochemical公司是开发和生产用于生命科学研究、诊断和生物技术应用的高质量纯化酶、蛋白质、核酸和细胞分离试剂盒的行业领导者。Worthington纯化的主要生化物质是

从胰腺、植物和发酵来源等材料中获得的蛋白质以及其他天然非动物和动物源物质。Worthington一直是世界上高纯度酶的主要来源。

从技术上讲，Worthington实际上并不生产酶：Worthington从各种动物和非动物来源、植物组织和各种微生物来源（例如细菌、真菌和霉菌）中提取和纯化酶。Worthington每种产品最重

要的特点是 -- 保持了跟体内一样的活性。蛋白质分子的大小和复杂性使得这一点变得困难，Worthington在自然条件下持续纯化酶和其他蛋白质的能力是该公司产品持续成功的关键。
