Fluorescence assay of nitrofurantoin with o-aminothiophenol in plasma and urine.

abstract：:For development and optimization of protein formulation sensitive analytical tools are required to follow both aggregation and changes in protein structure. The latter can be seen as the beginning of physical instability leading to aggregation. The focus of this work laid on the development of a novel analysis simulta...
