* The set of 192 barcode sequences used in KAPA UDI Adapters is exclusive to Roche.

** This is sufficient for four library preps with the KAPA HyperPrep or KAPA HyperPlus Kit if no adapter dilution is required.Generous overfill supports use on automated liquid handling system.

*** KAPA Adapter plates are shipped with peelable seals.Replacement seals for KAPA UDI Adapter Kits are peelable and pierceable whereas replacement seals for KAPA DI Adapters Kits are peelable only.
