The NGS Cell Free DNA Library Prep Kit (illumina and MGI Platforms) was developed for the construction of high quality cell-free DNA (cfDNA) libraries using 1 ng to 50 ng of cell-free DNA as input. The kit has a simple work flow and a fast procedure. Multiplexing of the cell free DNA library is possible based on the index type.

NGS Cell Free DNA Library Prep Kit Workflow

The main source of cell-free DNA (cfDNA) is derived from apoptotic hematopoietic cells in blood and found in the plasma. The length of the cfDNA is about 150-200 bp in length. Circulating tumor DNA (ctDNA) derived from malignant tumors is a part of cfDNA. Both cfDNA and ctDNA can be used as a noninvasive biomarker since it offers a better approach in comparison to invasive tissue biopsies.

NGS has been used for cfDNA and ctDNA sequencing in the field of liquid biopsy as it provides a whole genome level of molecular profiling. One of the hurdles for cfDNA sequencing is the difficulty of library preparation from the limited amount of cfDNA obtained from plasma. Our cell-free NGS kit makes it easy to get enough libraries from limited input in just 1.5 hours.

Three index types are available for the NGS Cell Free DNA Library Prep Kit of the illumina platform:

Non-index (Cat.# 30029): Libraries do not have index.

Index(Cat.# 30031): Each of our index primers contains a unique 6-base index sequence that can be used for sample identification. Total 48  library multiplexing is possible. Index information can be downloaded here.

Unique dual index (Cat.# 30033): Cell-free DNA library multiplexing up to 96 samples is possible with the unique dual indexes. We have developed a Four-Base Difference Index System. The system have at least 4 bases different from each other in the 8 bases index length. The primers effectively minimize sequencing errors such as mis-assignment, index hopping, index contamination etc. Index information can be downloaded here.

Indexes are available for the MGI platform kits (Cat.# 34031).

Kit advantages:

• Fast and simple protocol
  • Hands-on time is around 10 minutes
  • The total protocol time is only 1.5 hours
• Easy procedure based on:
  • Ready-to-use master mix for easy setup of reactions
  • Less reaction components to simplify bench work
• Less magnetic beads used for cleanup procedures: This can reduce more than 50% of the beads consumption
• Guaranteed high library conversion efficiency
• Low input cell-free DNA: From 1 ng to 50 ng

Description

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.

Details of the target and priming specificity are included in the individual handbooks above.

Packaged, optimised and ready to use. Expect Better Data.
