The collaboration will focus on identifying pre-clinical candidates for high-priority targets, including a small molecule oral therapy for immunological diseases.
Quantification and Characterization of Polysorbate-80 in Protein Formulations
March 2nd 2019HPLC coupled with charged aerosol detection is a suitable analytical technique to quantitate and characterize polysorbate-80 in therapeutic products; allowing quality assessment of raw material, content confirmation during manufacturing, and monitoring product stability.
Utilizing Spectral Analysis in HPLC Diode Array to Discover Impurities
March 1st 2019Investigation of peak purity failure during HPLC method validation led to discovery of a co-eluting impurity under the main peak. Spectral analysis, including three-dimensional modelling, was used to characterize the peak, leading to the development of a new HPLC method for analysing impurity content.
Best Practices for Immunogenicity Testing of Biologics
February 1st 2019Pharmaceutical Technology spoke with John Pirro, senior director of large molecule bioanalysis at WuXi AppTec, which provides anti-drug antibody (ADA) and neutralizing antibody (Nab) assay development, validation, and sample analysis services, about best practices to ensure that biologics are safe and effective.
