Multiplex Oligos for Illumina Systems (Dual Index Primers) (ChIP-seq, CUT&RUN)

Next generation sequencing (NG-seq) is a high throughput method that can be used downstream of chromatin immunoprecipitation (ChIP) and Cleavage Under Targets and Release Using Nuclease (CUT&RUN) assays to identify and quantify target DNA enrichment across the entire genome. Multiplex Oligos for Illumina Systems (Dual Index Primers) (ChIP-seq, CUT&RUN) contains adaptors and primers that are ideally suited for multiplex sample preparation for NG-seq on the Illumina Systems platform (Illumina, Inc.). This kit can be used to generate up to 96 distinct, barcoded ChIP-seq or CUT&RUN DNA libraries that can be combined into a single sequencing reaction.

Each kit component must pass rigorous quality control standards, and for each new lot the entire set of reagents is functionally validated together by construction and sequencing of indexed libraries on the Illumina Systems sequencing platform.

This product provides enough reagents to support up to 96 DNA sequencing libraries, and must be used in combination with DNA Library Prep Kit for Illumina Systems (ChIP-seq, CUT&RUN) #56795.

Multiplex Oligos for Illumina Systems (Dual Index Primers) (ChIP-seq, CUT&RUN) Protocol

I. Low Plexity Pooling Guidelines:

The dual index primer strategy utilizes two 8 base indices within each primer. Index 7 primers contain indices that are adjacent to the P7 sequence while index 5 primers contain indices that are adjacent to the P5 sequence. Dual indexing is enabled by adding a unique index to both ends of a sample to be sequenced. Up to 96 different samples can be uniquely indexed by combining each of the 12 index 7 primers with each of the 8 index 5 primers.

Illumina Systems NG-seq platforms use a red laser/LED to sequence A/C and a green laser/LED to sequence G/T. For each cycle, both the red and the green channel need to be read to ensure proper image registration (i.e. A or C must be present in each cycle, and G or T must be present in each cycle). If this color balance is not maintained, sequencing the index read could fail. Please check the sequences of each index to be used to ensure that you will have signal in both the red and green channels for every cycle. See example below:

IV. Set up the PCR Reaction

  1. Ensure that a valid combination of index 7 and index 5 primers is used. See Section I and II to verify that correct primer combinations have been selected.
  2. Add only one Index 5 primer (º) (5 µl) and only one Index 7 primer (•) (5 µl) to each PCR tube. It is critical to change tips between tubes to avoid cross-contamination. If necessary, discard the original Index 5 white caps or Index 7 orange caps and apply new caps to avoid index cross-contamination.
  3. Record the Index 5 and Index 7 primers added to each PCR tube.
  4. Add 25 µl Q5 PCR Master Mix (•) to each tube that contains primers.
  5. Add 15 µl of adaptor ligated DNA for a final volume of 50 µl to the corresponding tube. Gently pipette up and down 5–10 times to mix. It is critical to change tips between samples to avoid cross-contamination.
  6. Record the adaptor ligated DNA sample added to each PCR tube.
  7. Quickly centrifuge and perform PCR according to recommended cycling conditions (refer to the respective protocols in DNA Library Prep Kit for Illumina Systems (ChIP-seq, CUT&RUN) #56795 for ChIP-DNA or CUT&RUN DNA starting samples).

Up to 96 different samples can be uniquely indexed by combining each of the 12 index 7 primers with each of the 8 index 5 primers.

Illumina® NG-seq platforms use a red laser/LED to sequence A/C and a green laser/LED to sequence G/T. For each cycle, both the red and the green channel need to be read to ensure proper image registration (i.e. A or C must be present in each cycle, and G or T must be present in each cycle). If this color balance is not maintained, sequencing the index read could fail. Please check the sequences of each index to be used to ensure that you will have signal in both the red and green channels for every cycle. See example below:

IV. Set up the PCR Reaction

  1. Ensure that a valid combination of index 7 and index 5 primers is used. See Section I and II to verify that correct primer combinations have been selected.
  2. Add only one Index 5 primer (º) (5 µl) and only one Index 7 primer (•) (5 µl) to each PCR tube. It is critical to change tips between tubes to avoid cross-contamination. If necessary, discard the original Index 5 white caps or Index 7 orange caps and apply new caps to avoid index cross-contamination.
  3. Record the Index 5 and Index 7 primers added to each PCR tube.
  4. Add 25 µl Q5® PCR Master Mix (•) to each tube that contains primers.
  5. Add 15 µl of adaptor ligated DNA for a final volume of 50 µl to the corresponding tube. Gently pipette up and down 5–10 times to mix. It is critical to change tips between samples to avoid cross-contamination.
  6. Record the adaptor ligated DNA sample added to each PCR tube.
  7. Quickly centrifuge and perform PCR according to recommended cycling conditions (refer to the respective protocols in DNA Library Prep Kit for Illumina® (ChIP-seq, CUT&RUN) #56795 for ChIP-DNA or CUT&RUN DNA starting samples).

Product Description

Next generation sequencing (NG-seq) is a high throughput method that can be used downstream of chromatin immunoprecipitation (ChIP) and Cleavage Under Targets and Release Using Nuclease (CUT&RUN) assays to identify and quantify target DNA enrichment across the entire genome. Multiplex Oligos for Illumina Systems (Dual Index Primers) (ChIP-seq, CUT&RUN) contains adaptors and primers that are ideally suited for multiplex sample preparation for NG-seq on the Illumina Systems platform. This kit can be used to generate up to 96 distinct, barcoded ChIP-seq or CUT&RUN DNA libraries that can be combined into a single sequencing reaction. This product provides enough reagents to support up to 96 DNA sequencing libraries, and must be used in combination with DNA Library Prep Kit for Illumina Systems (ChIP-seq, CUT&RUN) #56795.

This product is compatible with SimpleChIP® Enzymatic ChIP Kit (Magnetic Beads) #9003, SimpleChIP® Plus Enzymatic ChIP Kit (Magnetic Beads) #9005, SimpleChIP® Plus Sonication ChIP kit #56383, and CUT&RUN Assay Kit #86652. This product is not compatible with SimpleChIP® Enzymatic Chromatin IP Kit (Agarose Beads) #9002 and SimpleChIP® Plus Enzymatic Chromatin IP Kit (Agarose Beads) #9004 because agarose beads are blocked with sonicated salmon sperm DNA, which will contaminate DNA library preps and NG-seq.

Specificity / Sensitivity

This kit has been validated in combination with DNA Library Prep Kit for Illumina Systems (ChIP-seq, CUT&RUN) #56795 to generate qualified DNA libraries using as little as 0.5 ng ChIP DNA or as little as 0.1 ng CUT&RUN DNA as starting materials. Libraries prepared from different starting amounts of DNA exhibit similar Agilent Bioanalyzer System profiles, genome mapping rates, numbers of identified binding peak, and signal-to-noise ratios across the whole genome.

Background

The chromatin immunoprecipitation (ChIP) assay is a powerful and versatile technique used for probing protein-DNA interactions within the natural chromatin context of the cell (1,2). This assay can be used to identify multiple proteins associated with a specific region of the genome, or the opposite, to identify the many regions of the genome bound by a particular protein (3-6). It can be used to determine the specific order of recruitment of various proteins to a gene promoter or to "measure" the relative amount of a particular histone modification across an entire gene locus (3,4). In addition to histone proteins, the ChIP assay can be used to analyze binding of transcription factors and co-factors, DNA replication factors and DNA repair proteins. When performing the ChIP assay, cells or tissues are first fixed with formaldehyde, a reversible protein-DNA cross-linking agent that "preserves" the protein-DNA interactions occurring in the cell (1,2). Cells are lysed and chromatin is harvested and fragmented using either sonication or enzymatic digestion. The chromatin is then immunoprecipitated with antibodies specific to a particular protein or histone modification. Any DNA sequences that are associated with the protein or histone modification of interest will co-precipitate as part of the cross-linked chromatin complex and the relative amount of that DNA sequence will be enriched by the immunoselection process. After immunoprecipitation, the protein-DNA cross-links are reversed and the DNA is purified. Standard PCR or Quantitative Real-Time PCR can be used to measure the amount of enrichment of a particular DNA sequence by a protein-specific immunoprecipitation (1,2). Alternatively, the ChIP assay can be combined with genomic tiling micro-array (ChIP on chip) techniques, high throughput sequencing, or cloning strategies, all of which allow for genome-wide analysis of protein-DNA interactions and histone modifications (5-8).
