Culture Media Dramatically Increase Protein Production
September 10, 2001?To meet the growing demand for recombinant proteins required
for proteomic research, Athena Enzyme Systems? (AthenaES) today announced it is
now marketing four proprietary media formulations requested by biotech customers
and not available anywhere else.
In controlled tests, the four proprietary blends resulted in cell yields
up to five times that of LB Broth, the industry standard for cultivating E. coli
bacteria used in the production and purification of recombinant proteins. Marketed
under the trade names Turbo Broth?, Superior Broth?, Power Broth? and Hyper Broth?,
the new media formulations demonstrate that accumulation of proteins greatly depends
on the media employed.
To determine which medium is best suited for a particular protein, AthenaES
is offering a Media Optimization Kit? that reduces the laborious process of media
optimization from several weeks to one day. The kit contains six foil packs containing
enough dry powder media to prepare one liter of each formulation. Four of the packs
contain Athena?s proprietary blends. The other two hold standard formulations?LB Broth
and Glucose M9Y?among those found to be most reliable for increased production of
recombinant proteins in E. coli.
The kit allows researchers to perform 40 optimization tests for rapid
identification of the best available medium for production of their specific protein
without the need for extensive testing or development work. By dramatically reducing
the time required for media screening from several weeks to one day, labs can save
thousands of dollars per application in costs for equipment, facilities and human
?As genomics research matures and more and more genes are identified,
researchers will need to produce the proteins encoded by those genes to continue
their course of work,? said AthenaES Chief Science Officer Dr. Sheldon E. Broedel,
Jr. ?By improving protein production, these new media formulations will help facilitate
those research efforts.?
Researchers at industrial, academic and government institutions can use the
proprietary formulations for basic and applied research in the areas of biomedical and
industrial applications, such as biopharmaceuticals, food processing, culture fermentations,
agriculture and pulp and paper production among others. The Media Optimization Kit? was
designed for research use only and should not be used for human diagnosis or drug use.
AthenaES has been manufacturing the proprietary media formulations since 1994
for internal use in its contract R&D and manufacturing services for customers. Repeated
requests by its customers led AthenaES to make the proprietary media available to the
