potential source of variability. Peptones designed for the biopharmaceutical industry are<br />

manufactured and released to strict specifications. In general, the variability that is observed<br />

when these peptones are used is the result of their use in a poorly understood biopharmaceutical<br />

production process. Through a comprehensive analysis of the spent media from<br />

multiple production runs using multiple peptone lots, key component concentrations can be<br />

identified and maintained at the appropriate levels. Once the process is properly controlled,<br />

the expected results will be consistently achieved.<br />

<strong>BD</strong> AutoNutrient Media Design Service (AMDS)<br />

Performing thorough optimizations can require significant time and resources, so the decision<br />

is often made to eliminate many potentially critical design points. By truncating the design, the<br />

desired production goal could be missed. To address this need and ensure the identification<br />

of the optimal media formulation that meets production goals, <strong>BD</strong> offers the AutoNutrient Media Design Service (AMDS). The <strong>BD</strong> team of dedicated, experienced scientists works with<br />

each customer in a highly collaborative process to develop a media formulation that satisfies<br />

the requirements. Through the AMDS program, <strong>BD</strong> offers a library of 45 diverse, chemically<br />

defined media, as well as a number of peptones designed specifically for the biopharmaceutical<br />

industry. Proprietary DOEs are used to optimize a base medium specifically for the cell line or<br />
