美国PBL InterferonSource  
PBL InterferonSource 是1990年建立的一家生物公司，主要生产干扰素 (Interferon)相关的生物产品，其创始人Sidney Pestka博士是干扰素研究领域 的先驱之一，正是他第一个应用基因重组技术生产出成熟有活性的干扰素，极大的推进了干扰素的研究和应用， 1980年Sidney Pestka博士首先生产出重组治疗用IFN-α提交FDA审批，并协助 FDA制定重组生物制剂的FDA评估程序和质量标准，23年后该准则仍被FDA沿用。鉴于Sidney Pestka博士在生物技术领域的杰出贡献，2002年布什总统在白宫特别授予其国家科技奖章。PBL InterferonSource发展到今天已能够提供各型干扰素蛋白、抗体以及检测试剂盒，PBL InterferonSource和其姊妹公司 PBL Therapeutics一起成为干扰素研究和应用领领跑者，其产品和服务几乎涵盖了所有的干扰素研究和应用领域。

Founded in 1990 by Sidney Pestka, M.D., PBL InterferonSource has become the premier supplier of reliable high-quality interferon products. We have grown each and every year since 1998, when we began direct sales to customers like you.

PBL started as a family business. Although we have grown substantially since that time, we have made it a point to retain the values that we grew up with: a single-minded focus on our scientific mission and business goals; and a particular concern for and commitment to each of our customers. We are also pleased to be able to support the mission of our "sister company" PBL Therapeutics, which is focused on developing interferon-based drugs to treat cancer.

PBL's goal has always been to facilitate the advancement of research. To that end, each year we aim to increase the quality and quantity of our products, to supplement our store of product information, and to provide scientists around the world with the support they require.
