HCP levels in clinical batches

Do you want to quantify host cell proteins in pre- or clinical batches?

Before entering clinical trials and submitting NDA or BLA, it is highly critical to determine the level of process-related impurities, Host Cell Proteins (HCPs). 

By applying mass spectrometry, you have the complete overview of the HCP content beforehand and avoid costly delays at later-stage trial approval. Also you can compare different clinical batches to check for manufacturing consistency. 

We identify and quantify the host cell proteins in purified drug substance batches by SWATH LC-MS/MS. The analysis provides a more detailed and accurate HCP documentation than HCP ELISA. The total HCP content is measured in nanogram HCP/mg drug substance (ppm), and each host cell protein is identified and quantified individually.

For pure drug substance batches with low HCP levels (1-500 ppm) you receive a highly sensitive and reproducible analysis. It both delivers identification and quantification of host cell proteins down to low ppm concentrations.

The HCP level analysis includes:

• Optimized sample preparation for pure drug substance samples
• Spike-in of internal standard proteins (0-2000 ppm) for quantification linearity and LOD
• LC-MS peptide analysis on a robust microflow HPLC and mass spectrometer, using SWATH LC-MS/MS for reproducible HCP identification and quantification
• Report with table of total HCP and individual HCPs amounts, as well as comparison between batches
