Our goal is to address critical measurement issues that exist regarding chemical and physical stability of biomacromolecules (proteins and DNA) in hydrophilic, hydrogen-bonding glasses such as those used in the biopharmaceutical industry. (nist.gov)
We use the following approach to develop measurement solutions for biopharmaceutical stabilization: 1) Use theory, simulation and experimentation to develop clear understanding of key relationships between glass properties and likely stability outcomes of proteins in the glasses. (nist.gov)
In 2004 we showed for the first time that the amplitude of local, high-frequency motions (on ns timescale, and Angstrom lengthscale) in hydrophobic glasses are key indicators of protein stability within those glasses. (nist.gov)
Since then we have shown that the impact of these high-frequency motions can dominate over all other measured properties in determining chemical and physical protein stability deep in the glassy state. (nist.gov)
We demonstrated that hydrogen bond network dynamics in glassy materials greatly impacts stability of proteins stored in those materials. (nist.gov)
