Product Info
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).
Kit advantages:
Fast protocol
The hands-on time is only 10 minutes
The total protocol time is around 1.5 hours
Simple procedure
Ready-to-use master mix makes it simple for reaction setup
Less reaction components
Less magnetic beads required for cleanup steps: Save the cost more than 50%
Low input DNA amount: Starts from 1 ng of DNA

The HiPure Mini system provides a fast, simple, and cost-effective plasmid DNA miniprep method for routine molecular biology laboratory applications. HiPure Plasmid Mini Kits use silica membrane technology to eliminate the cumbersome steps associated with loose resins or slurries. Plasmid DNA purified with Mini Kits is immediately ready for use. Phenol extraction and ethanol precipitation are not required, and high quality plasmid DNA is eluted in a small volume of Tris buffer or water.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method,then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – it takes only 2 minutes to obtain supernatant by optimized solution (10 minutes for other brands)
High yield – up to 70µg plasmid can be binded in one column
