Description

SeqMatic’s TailorMix dual indexed PhiX control library is a prepared adapter ligated library used as a control for Illumina sequencing instruments. Our custom indexed library eliminates PhiX contamination in multiplexed sequencing runs, enabling the generation of cleaner raw data and the option to analyze the PhiX reads for quality control purposes. Each tube contains 200uL of single stranded library prediluted in HT1 buffer to a concentration of 20pM, ready for spike in.

Note: A nondenatured PhiX is available for platforms using ExAmp cluster generation (NovaSeq, HiSeq X and HiSeq 3000/4000). Denatured PhiX is not compatible with those platforms.

Features

Positive Control Library for Illumina NGS

  • Compatible with most Illumina NGS systems including HiSeq 2500, MiSeq, and NextSeq

Customer Testimonials:

“PhiX contamination in our data used to be a significant issue given that we were sequencing viral DNA extracted from patient biopsies.  We no longer see PhiX contamination with your product, which ultimately streamlines our data processing and gives us additional piece-of-mind regarding the validity of our data.”

Eric Sherman
University of Pennsylvania

 

“My lab was noticing large amounts of bleed-through of Illumina’s PhiX v3 into our indexed samples. Seqmatic’s Indexed PhiX dramatically reduces this bleed-through and allows us to estimate our incidence of sequencing crossover contamination.”

Sample Sheet Setup

The TailorMix Indexed PhiX control library contains dual indexed barcodes which can be demultiplexed with all Illumina compatible demultiplexing software.

The TailorMix Dual-Indexed PhiX control library contains dual-indexed barcodes which can be demultiplexed with all Illumina compatible demultiplexing software. To monitor the percentage of PhiX reads in a sequencing run, include the TailorMix Dual-Indexed PhiX barcodes on the sequencing Sample Sheet for demultiplexing.

If the TailorMix Dual-Indexed PhiX barcodes are not included on the sequencing Sample Sheet, the PhiX reads will be parsed into a folder named “Unknown” or “Undetermined” along with any other reads with index sequences not defined in your sample sheet.

For individual downstream analysis of the Indexed PhiX library, your sample sheet can be modified to parse the PhiX reads into its own individual set of files. Simply add a new line to your sample sheet file containing the sequences below as your index barcodes. For single index read sequencing runs, only use the i7 Index 1 barcode sequence. The sequence length may also be adjusted as necessary to match the length of the index read.

i7 Index 1 barcode: TCGAATGA
i5 Index 2 barcode for MiSeq and HiSeq 2000/2500: GACATGCG
i5 Index 2 barcode for MiniSeq and NextSeq: CGCATGTC

  • TailorMix DNA or RNA
1% of final loading concentration
  • TruSeq Small RNA
  • TailorMix miRNA
5-10% of final loading concentration
  • PCR Amplicons (e.g. 16S, ITS, etc.)

  • Control Lane
  • PhiX Only Run
100% of final loading concentration

 

Storage Recommendations

The TailorMix Dual-Indexed PhiX Control Library is stable when stored at -20°C. Storage at -80°C has shown improved stability and is recommended for long term storage.

Best Practices

• Do not store the TailorMix Dual-Indexed PhiX Control Library in frost-free freezers.
• Aliquots should be made to allow for use to minimize repeated freeze/thaw cycles.
• Determine the appropriate aliquot volume based on usage.
• Aliquots that are in use can be stable for up to one month if kept on ice at all times during use and stored at temperature of -20°C or lower when not in use.
