Sample type purification kit guide
The 16S V2-V3 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V2-V3 amplicon libraries to be used for next-generation sequencing on Illumina platforms. All molecular reagents including primers, enzyme mixes, indexes, and buffers are provided. Instructions for PCR clean up with the AMPure XP Magnetic Beads (supplied by customer) are also included for rapid purification of nucleic acid products generated at two steps of the workflow. The library prep workflow could be used for purified DNA inputs from different sources including stool, soil, water, saliva, plant, urine, skin swab, vaginal swab, cheek swab, nasal swab, plasma/serum, tongue swab, gum swab, and others.
The 16S V2-V3 Library Preparation Kit for Illumina has a streamlined procedure that reduces the handling time such that the library prep procedure can be completed in approximately 4 hours (see diagram below). Input DNA is first subjected to targeted PCR to amplify the V2-V3 region of the DNA encoding 16S rRNA. The post-PCR reaction is then cleaned up using AMPure XP beads. Dual index primers are then added using a limited-cycle PCR. The indexed amplicons flanked by 5′ and 3′ barcoded adaptors are then cleaned using AMPure XP beads. The libraries are then ready for quantification, pooling and sequencing.

Storage Conditions and Product Stability
Norgen’s 16S V2-V3 Library Prep Kit for Illumina is shipped as one kit box (for the 24 prep kit) or two sub-component kits (for the 96 prep kit). All kits should be stored at -20°C upon arrival.
All kit components should remain stable for at least 1 year when stored at the specified storage conditions.

The kit was developed for construction of high quality libraries for next generation sequencing (illumina and MGI Platforms). 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 methods and physical methods (sonication, nebulization etc.). Library multiplexing is possible with different types of indexes.
The kit was optimized for next generation sequencing (NGS) library preparation with different types of samples. Most of DNA library preparation requires the ligation of sheared DNA fragments to library adaptors and the DNA library preparation is closely related to the quality of NGS data. With BioDynami’s unique DNA library preparation technologies, the fast and simple kit allows high quality NGS library preparation to be completed in 1.5 hours with only 10 minutes of hands-on time.
Some genomic regions are very difficult to be covered evenly and usually result in very low coverage rate or gap in these regions.
Typical difficult regions are:
• with high GC contents
• have secondary structures: mainly due to repeat sequences
• the worst cases: have both high GC contents and repeated sequences.
Example: human TERT gene is one of the most difficult regions as shown above. NGS data showed that BioDynami kit has the best performance to cover the extremely difficult human TERT gene region.
Limited GC bias across whole genome
Three index types are available for the illumina platform kits:
Non-index (illumina Cat.# 30009): Libraries do not have index.
Index (illumina Cat.# 30021): A unique barcode sequence with 6 bases has been included in each of the index primers. RNA Sequencing library multiplexing is possible with up to 48 samples. Index information can be downloaded here.
Unique dual index (illumina Cat.# 30023): RNA Sequencing library multiplexing up to 96 samples is possible with the unique dual indexes. We have developed a 4-Base Difference Index System. The system can generate indexes with at least 4 bases different from others in the 8-base indexing region. the unique dual indexing primers identify sequencing errors such as index hopping, mis-assignment, and de-multiplexing errors. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34021).

This kit provides a fast and simple procedure for the effective depletion of major serum proteins including albumin, α-antitrypsin, transferrin and haptoglobin from serum and plasma samples. Such abundant proteins usually obscure less abundant proteins in gel electrophresis making them difficult to visualize and recover. The kit reduces sample complexity to allow for convenient investigation of less abundant proteins. In other applications such as mass spectroscopy, fractionating abundant proteins improves the resolution of less abundant proteins. The kit is ‘generic’ in that it is not antibody-based and can thus be used to deplete abundant proteins from any starting material – human or various other animals – making it more versatile, flexible and affordable than other kits. Resulting proteins are ready for a range of applications including 2D gel electrophoresis, SDS-PAGE, Mass Spectrometry, Protein microarrays, DIGE (Difference Gel Electrophoresis) and more.
