KAPA Unique Dual-Index (UDI) Adapters contain 96 dual-indexed adapters, formulated at 15 µM in KAPA Adapter Dilution Buffer. Adapters are plated in hard-shell PCR plates and shipped with peelable sealing film. Of each adapter, 20 µL is supplied. This is enough for 4 library preparations with any KAPA DNA or RNA library preparation kit if standard protocols are followed and no adapter dilution is required. All kits are shipped with three (3) replacement films. KAPA Adapter Dilution Buffer (25 ml) is included in all complete kits, or may be ordered as a standalone kit.
