Why does the xGen™ cfDNA & FFPE Library Prep MC v2 Kit have fixed instead of random UMIs?
Fixed UMI sequences help to enable identification and correction of sequencing or PCR errors, even if they appear within the UMI sequence.
During error correction, using fixed UMI sequences reduces the chance that an error in UMI sequences will accidently be counted as a separate original molecule.
