Leaders in Biotechnology

Protein One, LLC is a biotechnology company doing business in Rockville, Maryland. The company is a provider of high quality, purified, biologically active proteins to customers including research labs, medical institutions and pharmaceutical companies.


Protein One’s expertise in active protein production will enable 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.


Protein One is in the process of developing a proprietary, immunotherapy platform and a series of specific cancer fighting antibodies. The company filed its first provisional patent in 2014 in this focus area.

Mission & Description

Protein One is a biotechnology company doing business in Rockville, 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.

Strategy & Focus

It is Protein One’s intent to maintain a leadership position in the proteomics industry by producing protein based Life Science Bioreagents. The purification of unique recombinant proteins, the creation of various protein array platforms and assay kits will enable scientists to further understand protein function and subsequently create new science applications and novel protein based drug discovery.


The scientific team continues to work towards the short term purification of a 500 recombinant protein catalog to include some complex, high market utility and very difficult to purify proteins many of which will only be available from Protein One. These diverse protein products associated with transcription, nuclear receptors, cancer and other diseases will form a basis for research use tools which will evolve into GMP products for clinical therapeutic and diagnostic utility in the near future.
