5x ER/A-Tailing Enzyme Mix

Product Description

5X ER/A Tailing is a NGS library preparation module that uses a one-step reaction to combine end-repair and dA-tailing to convert fragmented DNA into 5′-phosphorylated and 3′-dA-tailed DNA fragments enabling direct ligation of Illumina sequencing adapters. When used in combination with the 5X WGS ligation module (L6030-W-L), the optimized chemistry ensures high sensitivity for low input DNA, high ligation efficiency for maximum library yield and a workflow that is under 3 hours with less than 45 minutes hands on time.

Quality Control Analysis

ER/A Tailing Enzyme Mix Functional Assay: QC Library length must be within 15% of the reference library length. Concentration of the QC library generated from 100 ng input DNA (average ~300 bp fragments) is >60 nm with mapped reads > 90%. For QC library, normalized coverage should be within 0.7 to 1.3 for most of the genome (10% – 80% GC content).

Supplied with:  B9420 10x ERA Buffer
