The ddPCR E. coli (Escherichia coli) Residual DNA Quantification Kit is designed for the quantification of residual host cell DNA (HCD). HCD carried over during the process of manufacturing therapeutic proteins and vaccines poses safety concernsand must not exceed levels established by regulatory agencies such as the U.S. Food and Drug Administration and the World Health Organization. The ddPCR E. coli Residual DNA Quantification assay is a 20x concentrated, ready-to-use primer-probe mix, and the ddPCR Supermix for Residual DNA Quantification is a 2x concentrated, ready-to-use supermix. The kit is compatible with uracil DNA glycosylase (UDG) for use in decontamination procedures.
