Host Cell Proteins Analysis

The development and validation of a process specific assay for host cell proteins (HCP) determination in therapeutic recombinant proteins should follow the specifications contained in monograph 2.6.34 of the European Pharmacopeia in a step by step approach:

1. Production of the HCP antigens

Electrophoresis in Quality Control of Biologics

Electrophoresis is an analytical technique widely used for purity determination and identification of therapeutic proteins. This technique is based in the migration of the proteins under an electrical field according their electrophoretic mobility. Depending of the type of the electrophoresis, different quality attributes of the protein can be measured. Sensitivity, robustness and throughput will depend of the format used, being the classical flat/vertical gel formats displaced by the newest capillary formats due to their inherent advantages.

In-Use Microbial Stability

In-use stability testing for multidose products was initially based in the Note for Guidance on In-use Stability Testing of Human Medicinal Products of the CPMP of the EMA, in March 2001. According to it the purpose of in-use stability testing is to establish a period of time during which a multidose product can be used whilst retaining quality within an accepted specification once the container is opened.

Elemental Impurities in Purified Water

In line with the Ph. Eur. implementation strategy for the ICH Q3D guideline for elemental impurities, the test for heavy metals (2.4.8) has been deleted and a new section is included: “If purified water in bulk does not meet the requirement for conductivity prescribed for Water for injections (0169) in bulk (1.3 µS/cm), a risk assessment according to general chapter 5.20 Elemental impurities is carried out.
