Research Statement:

The Laboratory’s main interest is production and purification of biological products from both prokaryotes and eukaryotes of native and recombinant strains. Our work involves all aspects of this process including research, development, and production. To accomplish this mission, the Laboratory includes a pilot production facility that is well-equipped with recovery and purification equipments and bioreactors of various sizes and configurations for propagation of biological systems such as mammalian cells, insect cells, bacteria, yeast, and fungi. The biological products we make support clinical and structural studies.

The Laboratory conducts research and process development based on growth optimization, production scale-up and product recovery processes. We concentrate on protein production and purification with an emphasis on scaling up. One of the current research topics is aimed to achieve better understanding of the growth behavior and metabolism of both E. coli and several mammalian cell lines. The objective is to be able to overcome specific difficulties in the growth and the production process by modifying the properties of the producers. This work involved with gene transcription and expression analysis as well as cells transfection and mutation. Our recent achievement is identifying genes involve in mammalian cell adhesion, which allow us to modify the way the cells grow.
