Advances in the Human Genome Project have demanded innovative solutions to sample preparation in the ever-changing landscape of molecular labeling and manipulation, gene mapping, gene expression, amplification, DNA sequencing and proteomics. Accordingly, Princeton Separations has developed an expanding line of products for molecular separations in genomics and proteomics. PSI continues to develop its fluorescent polarization technology, focusing on applications in environmental science and molecular biology. The company is a registered manufacturer with the FDA and DEA, specializing in molecular separations for the research, diagnostics and pharmaceutical communities. It maintains good manufacturing practice production in its facility in Freehold, N.J. PSI was established in 1984.
