The NGS Low Input DNA Library Prep Kit (illumina and MGI Platforms) was developed for construction of high quality NGS libraries with low input DNA amount from 1 ng to 400 ng. The kit allows scientist to study samples with limited DNA such as tumor samples, patient samples, and other specially collected samples (FACS sorting etc.). The kit has high library conversion efficiency with as little as 1 ng DNA input. The fast and simple 1.5-hour protocol makes libraries with even coverage and low GC-bias based our unique chemistry for DNA end-polishing and ligation.
The kit needs double strand DNA fragments (blunt and/or sticky) as input DNA for NGS library preparation, and is compatible with DNA fragments generated from both enzymatic approach (for example, BioDynami DNA fragmentation enzymes, Cat.# 40061 and Cat.# 40062) and mechanical approaches such as sonication and nebulization etc.
NGS Low Input DNA Library Prep Kit Workflow
Three index types are available for the NGS Low Input DNA Library Prep Kit of illumina platform:
Non-index (Cat.# 30022): Libraries do not have index.
Index (Cat.# 30024): Each of our index primers contains a unique barcode sequence with 6 bases that can be used to identify the low input DNA libraries. Library multiplexing up to 48 samples is possible. Index information can be downloaded here.
Unique dual index (Cat.# 30025): Library multiplexing up to 96 low input DNA libraries is possible with unique dual indexes with our Four-Base Difference Index System. The system allows us to make indexes for the libraries that have at least 4 bases different from each other in the 8-base barcode length. Our unique dual index primers can reduce sequencing errors such as de-multiplexing errors, amplification errors, mis-assignment of reads, index cross-contamination, and also index hopping. The kit includes 96 pre-mixed unique pairs of index primers. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34024).

The PCR Decontamination Kit can remove contaminating DNA in PCR master mixes, without reduction of PCR sensitivity.
Decontamination of master mixes without reduction of sensitivity has always been a challenge. Especially when minor amounts of DNA are targeted, contaminating DNA is a major problem. Any loss of sensitivity in the qPCR assay caused by the decontamination protocol is unacceptable.
In Figure 1, it is demonstrated that the PCR decontamination kit can remove contaminating DNA from a qPCR mix to non-detectable levels (flat NTC), without affecting the sensitivity of the qPCR.
