Host cell impurity analysis
WebOct 19, 2024 · Host cell protein (HCP) is the largest protein contaminant in biopharmaceuticals, derived from recombinant DNA technology. Most biotherapeutics use recombinant DNA technology to express target protein drugs using preferred host cells. Since host cells also express a large amount of protein, recombinant protein drugs will be … WebThe SWATH mass spectrometry technology is a data independent acquisition strategy used for e.g. residual protein and process related impurities analysis. This means that all MS/MS fragmentation data for every peptide in your sample is collected. This is only possible due to the high speed of modern mass spectrometers.
