Product Description
Technical Specifications
Sample Input | Purified microbial DNA ≤100 ng, free of PCR inhibitors. |
---|---|
ITS Primer Sequences (adapters not shown) | ITS3f (GCATCGATGAAGAACGCAGC, 20 bp), ITS4r (TCCTCCGCTTATTGATATGC, 20 bp). |
Index Primers | Dual index (barcodes) to uniquely label samples. |
Barcode Sequences | 10 bp barcodes, Available for download here (USA Only), or by visiting the Documentation section of the D6425 Product Page at www.zymoresearch.com. |
Amplicon Size | The final amplicon size after 1-Step PCR (targeted amplification and barcode addition) is ~480 bp. |
Sequencing Platform | Illumina MiSeq® without the need to add custom sequencing primers. Zymo Research recommends the MiSeq® Reagent Kit v3 (600-cycle). For assistance with sample sheet setup, see Appendix F. |
Required Equipment | Microcentrifuge, plate spinner (centrifuge), 96-well real-time quantitative PCR system (SYBR Green compatible) or standard PCR system, and 96-well real-time PCR plates. |

Q1: What samples are compatible with this kit?
Purified total DNA from any organism free from PCR inhibitors. This system has been used by Zymo Research’s Microbiomics Services team to process samples from human, water, soil, food, plants, feces, biofilms, and much more.
Q2: What is the minimum DNA input for this kit?
The system has been tested with inputs as low as 100 femtograms with no significant impact to the performance of the kit.
Q3: Why does the kit use only a single PCR amplification step?
This single PCR step combines targeted amplification of the microbial genome and the barcoding index PCR, which allows for a simple and fast workflow.
Q4: How does the kit achieve normalization?
The combination of using Equalase™ qPCR Premix to yield roughly equal amounts of libraries and a carefully curated barcode index list results in similar raw sequencing reads across samples.
Q5: What is the difference between the two standards included in the kit?
The ZymoBIOMICS® Microbial Community DNA Standard consists of purified DNA from 8 bacteria and 2 yeasts and is useful for assessing community profile bias. The ZymoBIOMICS® 16S/ITS qPCR Standard consists of a plasmid that has a single bacterial and single fungal target and is useful for quantifying copy number. Both are useful as positive controls for the library prep process.
Q6: Why is the library amplicon size not well defined in DNA fragment analysis?
Equalase™ amplification and the library prep design may cause some library products to not anneal well, causing a lack of a tight band. These libraries are perfectly fine because preparation for Illumina sequencing includes denaturing libraries into single strands.
Q7: What is the difference between this kit and the Quick-ITS™ Plus NGS Library Prep Kit (D6424)?
The Quick-ITS™ Plus NGS Library Prep Kit (D6424) uses a combinatorial barcoding scheme, which combines 16 forward and 24 reverse indexes to provide 384 barcode combinations. The Quick-ITS™ Plus NGS Library Prep Kit (UDI) (D6425) uses 768 unique index sequences (384 forward, 384 reverse) to provide 384 completely unique barcode combinations. The Quick-ITS™ Plus NGS Library Prep Kit (UDI) (D6425) is also provided with the Equalase™ qPCR Premix pre-aliquoted into the primer plate, further reducing the amount of hands-on time required.
