StepWise DNA Lib Prep Kit (RK20202)

Datasheet

Summary

Product nameStepWise DNA Lib Prep Kit
Catalog No.RK20202
Input DNA amount500 pg-1000 ng
SequencerIllumina
The StepWise DNA library preparation kit is designed for illumina DNA sequencing library construction as little as 500 pg, up to 1000 ng. The kit can be used to perform PCR-free DNA library preparation, in which adaptors contain the complete sequence required for hybridization of the templates to the flowcell surface, and for annealing of sequencing primers. The minimal input for preparing PCR-free library is 100 ng of high quality genomic DNA, or 10 ng circulating cell-free DNA (cfDNA). PCR primers are included for users who wish to use self-selected DNA polymerase in the library amplification.
The entire workflow of StepWise DNA library preparation kit is shown as the below.

The Low EDTA TE buffer and PEG/NaCl solution can be stored at room temperature or 4°C. All other components should be stored at -20°C. The shelf life of all reagents is one year when stored properly.

01. Please you use high quality DNA as possible as you can. Heavily nicked or damaged DNA may cause library preparation failure. You can use 260 nm/280 nm ratios (1.8~2.0) to check DNA purity. You also can use fluorescent method to perform double-stranded DNA quantification. Contaminating RNA, nucleotides and single-stranded DNA may affect the amount of usable DNA in a sample preparation.

02. Please mix by gently pipetting the reaction mix up and down.

After adaptor ligation, clean up step is designed to remove low molecular weight materials. Size selection step is also designed for users who want to perform size selection for their libraries. If your input DNA is less than 50 ng, size selection is not recommended.

The kit also can be used to perform PCR-free DNA library preparation, in which adaptors contain the complete sequence required for hybridization of the templates to the flowcell surface, and for annealing of sequencing primers.You also can use customized or other commercial PCR-free Y-shape adaptors for illumina sequencing plateform.

In the amplification step, you also can use yourself-selected DNA polymerase, and PCR primers are included in this kit.

Adaptor:


Primer1:  5’-AATGATACGGCGACCACCGAG

Primer2:  5’-CAAGCAGAAGACGGCATACGAG
