ProteinOne公司位于美国马里兰州马里兰大学园区，主要研发和生产纯化的活性蛋白质和蛋白质芯片平台，应用于研究实验室、医学院校和制药公司等单位。公司来自NIH的专家及一流的专业技术是质量和信心的保证。
ProteinOne公司成立于2000年10月，创始人认为在后基因组时代对纯化活性蛋白和有关设备如通用蛋白芯片系统的需求越来越大。ProteinOne公司的目标是在两年内提供300多种纯化活性蛋白。
ProteinOne产品主要有：蛋白质系列、客户定义蛋白质服务和蛋白质芯片平台。
公司提供客户有活性的高纯度重组蛋白和天然的哺乳动物细胞内蛋白。产品类型包括普通转录因子、转录激活因子和辅助因子、mRNA前体处理因子、肿瘤抑制因子和其它肿瘤相关蛋白。

ProteinOne is a development stage biotechnology company doing business in Bethesda Maryland, USA. The primary aim of the company is to deliver purified, biologically active proteins to research labs, medical institutions and pharmaceutical companies via a Universal Protein Array (UPA) under development by the company to help companies with their drug discovery program.
The purified proteins will be sold in two different formats: through the patent pending UPA system, or Individually by request. The company’s aim is to include over 300 purified active proteins in our inventory within two years, and to successfully transfer from a prototype to an operationally complete model of the UPA.
ProteinOne's expertise in active protein production allows us to provide customers with functionally active and highly purified recombinant proteins as well as native protein fractions from mammalian cells. Our product lines include general transcription factors, transcriptional activators and coactivators, pre-mRNA processing factors, tumor suppressors and other cancer related proteins. 
ProteinOne was incorporated in Delaware in October 2000. The founders believe that there exists a tremendous need for both purified, functional proteins, and delivery devices such as the Universal Protein Array system, to extend the research and commercialization of Human Genome discoveries in the post-genomic world.
ProteinOne was formed with a strong management team solidified by scientific expertise from the National Institutes of Health (NIH), and has negotiated certain licenses for the UPA to be implemented at our discretion.
In 2001, ProteinOne entered the Technology Advancement Program (TAP) at the University of Maryland, an internationally recognized business incubator providing modern laboratory facilities and centralized university affiliation.
ProteinOne continues its growth and has established itself as a leader in the medical research field with their innovative protein bioreagents. The company graduated from the TAP in 2005 and now occupy their new laboratories and administrative offices in Bethesda, Maryland.
