Founded in 1984, Bio-Synthesis, Inc. was first known as OCS Laboratories. It was the first producer of commercially available synthetic DNA and, in 1985, became a producer of synthetic peptides. In 1989, OCS incorporated as Bio-Synthesis, Inc. and moved its laboratories to Lewisville, Texas. Today, BSI occupies 10,000 square feet of modern laboratory space (completed in 1995) located 20 miles from downtown Dallas and 10 miles from D/FW airport. Among the surrounding academic institutions are: University of Texas Southwestern Medical School (12 miles), University of North Texas (10 miles), and University of North Texas Health Science Center (25 miles). These universities provide excellent library resources. Since its inception, BSI has steadily expanded its product lines and services to meet the growing needs of the molecular biology community. It has maintained its position as an aggressive, innovative company in a highly competitive marketplace without sacrificing quality. In the beginning, our primary emphasis was on synthesizing high quality DNA primers and linkers, which were the initial uses of oligos. Today, newer technologies, such as gene construction, PCR, mutagenesis, combinatorial libraries, dye/adduct labeling, DNA microarrays, peptide-nucleic acid chimeras, etc. have challenged the molecular biology field. In response, BSI has branched into several related areas including DNA paternity testing, DNA HLA typing, PNA synthesis, genomic sequencing, fluorescence-based genotyping, custom organic synthesis and other molecular biology based applications.


The Research and Development Division comprises a number of Ph.D. and M.D. professionals with backgrounds in molecular biology, immunology, nucleic acids, peptide synthesis, general organic chemistry, and automated amino acid sequencing. The Molecular Biology Division is set up to handle most modern experimental procedures; the Immunology Division specializes in immunodiagnostic-based reagents.

Not only has BSI continued to provide quality DNA products and services for the research community, but it has also become a world leader in providing custom peptide products and services. Using state-of-the-art solid phase peptide chemistries, BSI provides high quality custom peptides, performs carrier conjugations, antipeptide antibody production, antigenic peptide design, synthesis of long and/or modified peptides, MALDI TOF analysis, contract research, consultation services and more.

Biomedical researchers worldwide in universities, biotech companies, private clinics, and government agencies use products from Bio-Synthesis, Inc. in studies ranging from PCR diagnostics to cancer research and the Human Genome Project.
