In addition to the upstream library preparation steps, the Library Prep Kit for myBaits includes the reagents necessary for performing the post-capture amplification step of the myBaits protocol.
The Library Prep Kit includes reagents for end-polishing/A-tailing, enzymatic fragmentation, ligation of user-supplied adapters, purification, and amplification (with user-supplied indexing primers, or kit-supplied universal P5/P7 primers if using full-length adapters).
In addition, the kit also provides sufficient reagents for the amplification and purification steps at the end of the myBaits capture protocol (myBaits kit sold separately).
Full details of what is included in the kit and what reagents/equipment are required to complete the protocol can be found in the kit manual.
The Library Preparation Kit for myBaits is intended to be used for the preparation of NGS libraries from DNA samples prior to hybridization capture with myBaits.
Compatible DNA samples should be or have:
Libraries made with this protocol are directly compatible with downstream myBaits enrichment (or another hybridization capture system), or alternatively can be sequenced directly in order to generate non-enriched read data.
No. myBaits hybridization capture kits have always been– and will continue to be– compatible with any user-provided upstream NGS library preparation system that is appropriate for a given project.
However, for your convenience, we are now offering our own powerful kit for preparing NGS libraries from most types of DNA samples, which is relevant for many myBaits hybridization capture projects. This new product (Library Preparation Kit for myBaits) is intended to be used for the preparation of NGS libraries from dsDNA samples prior to hybridization capture with myBaits.
In addition to the upstream library preparation steps, the Library Prep Kit for myBaits includes the reagents necessary for performing the post-capture amplification step of the myBaits protocol.
The Library Prep Kit for myBaits is compatible with a wide range of pre-built or DIY adapters or primers. The adapters used must be T-overhang-containing double-stranded adapters. These can be either short (“stubby”) adapters OR full-length adapters that contain sample-specific barcodes. If using stubby adapters, indexing primers that add universal P5 and P7 priming sites are also required. See the kit manual for further technical information about adapters and primers.
We recommend using unique dual indexes. When selecting indexes, ensure that all libraries that you ever plan to co-enrich or co-sequence have unique index combos.
For your convenience, below are listed some commercially-available adapter and barcoding solutions designed for Illumina(R) short-read sequencing, but other vendors also supply compatible options.

The Library Prep Kit for myBaits is designed for input amounts from 1 to 500 ng. Please see the kit manual for technical recommendations.
Please see the kit manual for detailed technical recommendations on the enzymatic fragmentation step. In brief, the final length of your DNA after fragmentation will depend on the (1) the length of your starting genomic DNA sample and (2) your chosen fragmentation time.
myBaits hybridization capture can tolerate NGS library insert lengths from 50bp-10Kbp. However for most myBaits applications, users should aim to generate NGS libraries with ~300-500bp length inserts (~450-650bp length libraries).
Yes, the Library Preparation Kit for myBaits is compatible with a wide range of input DNA qualities, from high-molecular weight to highly degraded.
However, some degraded sample types (such as formalin-fixed, ancient DNA, and others) may have chemical modifications, crosslinking, sequence breaks, or other types of damage that can restrict the conversion those DNA molecules into a functional NGS library. In order to be compatible with this Library Prep Kit, the target DNA molecules must be double-stranded and able to be enzymatically end-polished and adenylated (A/T overhang) to enable ligation of the sequencing adapters.
Regardless, the enzymatic fragmentation outcome will be affected by the starting length of your DNA samples. Please see the kit manual for technical recommendations for selecting the correct fragmentation approach for your project goals. In brief, the final length of DNA after fragmentation will depend on the (1) length of starting genomic DNA and (2) the chosen fragmentation time.
Yes! From our team of experts, we offer comprehensive NGS laboratory and bioinformatic services appropriate for a wide range of sample types. We offer flexible services including DNA/RNA extraction, NGS library preparation, myBaits capture, short- or long-read sequencing, and/or bioinformatic analysis.
All of Arbor’s library preparation service options are AVITI-compatible.
Please see the library kit compatibility guide from Element Biosciences for a list of kits with which AVITI sequencing is compatible.
Briefly, compared to the figure below, the 5’ and 3’ end of the adapters must not have missing, additional, or mismatched bases or modifications that would block DNA ligation:
