Popis: | Protein concentration is a critical product quality attribute and required for any therapeutic protein. Many commercial and investigational new biologics are now formulated at high concentrations (>100 mg/ml) to achieve successful subcutaneous administration. Assaying protein concentration in high concentration formulations poses a challenge, as traditional absorption spectroscopy and UPLC/HPLC (ultra/high performance liquid chromatography) assays cannot accurately measure such high concentrations without further solution manipulation. However, recent advances in UV/vis technology have led to the creation of instruments that measure samples at relatively short ( |
