Purification of Recombinant Plant-Made Proteins From Corn by Ultrafiltration

Nov 10, 2009
Matthew Aspelund
The use of corn as an expression host is an attractive system for the production of plant-made proteins. The use of plants lowers upstream costs making downstream the significant production cost. For some proteins, crossflow ultrafiltration could be a lower cost alternative. The potential for doing...

Gram-Scale Isolation of IEC Charge Variants Using Displacement Chromotography

Nov 10, 2009
Ryan Hutchinson
The pharmacokinetic profiles of monoclonal antibody charge variants are poorly understood because they differ only slightly from the “main” antibody species, are low in abundance, and extremely difficult to isolate in pure pools for intensive in vitro and in vivo studies. Because of this, the...

Optofluidic SERS Devices for Biomolecular Detection

Nov 9, 2009
Yun Suk Huh
Recently, Surface-enhanced Raman scattering (SERS) has attracted great attention because of its high sensitivity, label-free detection, and low detection limit. Additionally, it provides a specific fingerprint spectrum of multiplex samples with narrow band width. Because of these advantages, a...

Stability and Reactivity of Enzymatic Papers

Mohidus Samad Khan
Bioactive papers and paper diagnostics are getting a reality for their low cost, selectivity and application flexibility. Critical is the thermal stability of bioactive papers that need to be shipped and stored. This study quantifies the thermal stability and reactivity of enzymatic bioactive...

Rapid Surface Enhanced Raman Scattering (SERS) Viral Assays

Nov 9, 2009
Patrick A. Johnson
Rapid and accurate detection is the key to controlling the spread of viral pathogens. Recent advances in the field of surface enhanced Raman scattering (SERS) spectroscopy have demonstrated the utility of this technology in diverse research disciplines ranging from surface chemistry and...

Optimizing the Industrial Gas Supply Chain

Nov 9, 2009
Jim Davis
Smart process manufacturing (SPM) refers to a design and operational paradigm involving the integration of measurement and actuation; environment, safety, and health (ES&H) protection; regulatory control; real-time optimization and monitoring; and planning and scheduling. It is motivated by...

Aerobic Fermenter Scale-up: Why Equal Mass Transfer Scale-up Doesn't Always Work

Nov 9, 2009
Julian B. Fasano
Transferring oxygen to the liquid is only one of several steps that must occur in an aerobic fermentation. After the oxygen is transferred to the liquid, the liquid must be thoroughly mixed throughout the vessel. Then the oxygen must diffuse through the cell wall before finally being metabolized...

A Standardized Approach to Smart Manufacturing

Nov 9, 2009
Pete Sharpe
Advanced Process Control (APC) is a key element of the Smart Manufacturing paradigm, that helps drive the operation toward it's optimum point. For many common processes, such as distillation columns, fractionators, fired heaters, boilers or blenders, the APC strategies, calculations and control...

Commercial-Scale Energy Crop Production: Establishing Switchgrass in Tennessee

Nov 9, 2009
Timothy Rials
With the advancement of cellulosic ethanol technologies in recent years, more emphasis is being placed on the production of a sustainable supply of biomass for commercial scale facilities. These facilities will require significant supplies of biomass that will, in the southeast, come from private...
