R&D Systems位于美国的明尼苏达州，一直致力于生物制品的开发与生产。公司成立之初主要生产用于医院及临床应用的血控品。1977年，公司推出第一个产品--富血小板血浆质控品；1981年，公司成为全球第二家生产含血小板全血控品的供应商。40多年的发展中，R&D Systems仍持续开发各种血控品产品。

1985年，作为公司推出的第一个科研试剂产品，也是全球第一家将该产品进行商业化生产的产品，R&D Systems成功上市了TGF-beta1蛋白。作为胞外信号分子，TGF-beta1蛋白在多种细胞中进行表达，并作为胞外信号分子参与免疫功能，细胞增殖和细胞分化等生物学过程。该产品推出后，公司陆续从生物材料中纯化了几种细胞因子产品并推向市场。天然蛋白类产品的成功推广，加速了R&D Systems在细胞因子市场的开拓。公司于1985年形成Growth Factor事业部（现Biotechnology事业部）。Biotechnology事业部的目标是生产和营销重组人细胞因子。与天然来源提取蛋白相比较，DNA重组技术生产的蛋白产品其成本更低，产量更高，完全摆脱原料的限制。1989年，Biotechnology事业部开始开发抗细胞因子的单克隆和多克隆抗体，并于1990年开发了第一个ELISA试剂盒。
