NIST Spectroscopic Measurement Standards
The National Institute of Standards and Technology (NIST) has developed Standard Reference Material (SRM) 2082 as a pathlength standard for UV absorbance measurements for use with the new generation of microvolume spectrophotometers and short-pathlength cuvettes.
Complementary Techniques for the Detection and Elucidation of Protein Aggregation
February 1st 2016In this article, the author reviews some of the techniques that can yield valuable information on protein stability, focusing specifically on protein aggregation. Emphasis is placed on the enhanced information made available when technologies are used orthogonally, and the alignment of different approaches with specific stages of the biopharmaceutical development workflow.
