The SeqCap® EZ HE-Oligo Kit A is used to block library adapters in hybridization to prevent secondary capture. The kit is intended for customers performing sequence capture and using Illumina sequencing systems.

It includes hybridization enhancing (HE) oligos for barcoding 1 to 12 samples corresponding to Illumina's TruSeq Library Kit A; each HE oligo can be used for 8 separate reactions.

To ensure proper matches in the hybridization step, the DNA Adapter Index from the Adapter Kit A correspond to the HE Oligo from this kit.
