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

Introduction

HiPure Bacterial RNA Kit uses silica gel column purification to simplify the extraction. The whole process does not require phenol chloroform extraction and time-consuming alcohol precipitation. The kit is suitable for efficiently extracting RNA from various bacterial samples. The purified RNA can be directly used for RT-PCR, Northern hybridization, etc. The kit has included lysozyme and glass beads, which can be used to treat gram-negative bacteria which is easy to be lysed, as well as gram-positive bacteria which is hard to be lysed, including enterococcus faecalis, staphylococcus, etc.

Specifications

Principle

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

Advantages

• Fast – several samples can be extracted in 30 minutes
• High purity – the purified RNA can be directly used in various downstream applications
• High recovery – RNA can be recovered at the level of PG
• Good repeatability – silica gel column purification technology can obtain ideal results every time
• Broad spectrum – it can deal with various bacteria, including Gram-positive bacteria that are difficult to be lysed
• Sufficient components – the kit contains carried lysozyme and glass beads

Storage and Stability

The kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions. Due to the lack of antibacterial agents, RNase Free Water may be contaminated by bacterial or fungal when placed or operated at room temperature. It is recommended to pack and store at 2-8°C to reduce contamination.
