Molecular Biology

LORRE has the facilities, equipment, and expertise to conduct molecular biology research, such as cloning genes, developing gene knock-outs, gene expression profiling, intracellular enzyme expression assays, metabolic engineering, and classical strain development for bacteria and yeast. We have unique expertise in the molecular biology of Saccharomyces cerevisiae yeast. Coupled with our fermentation facilities and analysis capabilities, LORRE is uniquely positioned to take a gene from cloning through expression and strain development to process integration and engineering assessment of protein production or metabolic engineering performance.
