Low Endotoxin Recovery—Masking of Naturally Occurring

Feb 15, 2019 · The different buffer systems as well as the filtration had no major effects on the detectability of the endogenous endotoxin contamination of the antibody. Only small differences between the activity before and after the filtration step were observed. As expected, no masking was observed in the buffer systems containing only the chelating agent.
