Specific-Locus Amplified Fragment Sequencing (SLAF-Seq)

Workflow

The service has some pre-design in silico to guarantee the optimal enzyme selection on the preparation of the library.

Technical Scheme

Service Features

● Sequencing on NovaSeq with PE150.

● Library preparation with double barcoding, enabling pooling of over 1000 samples. 

● Independent of reference genome:

            With reference genome: SNP and InDel discovery

            Without reference genome: sample clustering and SNP discovery

● In the in-silico pre-design stage multiple restriction enzyme combinations are screened to find the ones that generate a uniform distribution of SLAF tags along the genome.

● During the pre-experiment, three enzyme combinations are tested in 3 samples to generate 9 SLAF  libraries, and this information is used to choose the optimal restriction enzyme combination for the project.

Recommended Sample Delivery

Container: 2 ml centrifuge tube

(For most of the samples, we recommend not to preserve in ethanol)

Sample labeling: Samples need to be clearly labeled and identical to submitted sample information form.

Shipment: Dry-ice: Samples need to be packed in bags first and buried in dry-ice.
