Thousands of bacterial proteins are present at the start of purification. Chromatography removes almost all, but a few that resemble the product in size or charge co-purify at trace levels. The assay uses polyclonal antibodies raised against a null-strain lysate so that it detects the mixture rather than any one protein. The result is a total.
It is the immunogenicity-relevant impurity class for a recombinant product.
Host chromosomal and plasmid DNA fragments. Measured by amplifying a host-specific sequence or by a DNA-binding dye. Limits for therapeutic proteins are in the picogram-to-nanogram per dose range; research material reports the figure obtained.
Both this and host-cell protein are process-related impurities, distinct from the product-related variants such as oxidised forms.
A synthetic peptide is built from protected amino acids on a resin; no organism is involved. Its impurities are deletion sequences, incompletely deprotected forms and residual reagents. The two certificate types answer different questions because the two products are made differently.
