Multiplex Oligos for Illumina® (Single 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® (Single Index Primers) (ChIP-seq, CUT&RUN) contain adaptors and primers that are ideally suited for multiplex sample preparation for NG-seq on the Illumina® platform (Illumina, Inc.). This kit can be used to generate up to 12 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® sequencing platform.

This product provides enough reagents to support up to 24 DNA sequencing libraries, and must be used in combination with the DNA Library Prep Kit for Illumina® (ChIP-seq, CUT&RUN) #56795.

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

I. Low Plexity Pooling Guidelines:

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:

indexing table

The following table lists some (but not all) valid index combinations that can be sequenced together:

Valid index combinations that can be sequenced together

Multiplex Oligos for Illumina® (Single Index Primers) (ChIP-seq, CUT&RUN) can generate 12 different, barcoded samples if each Index primer is used only once with Universal PCR Primer for Illumina®. Each Index Primer is supplied in sufficient amounts to generate two libraries, but these two libraries cannot be pooled together in one sequencing lane.

For 1-plex (no pooling), use any index primer with the universal PCR primer.


II. Index 1-12 Primers for Illumina®:

Each Index Primer for Illumina® is provided in volume of 10 µl.

Where -s- indicates phosphorothioate bond.


III. Set up the PCR Reaction

  1. Ensure that a valid combination of index primers is used. See Section I and II to verify that correct primer combinations have been selected.
  2. Add only one index primer (•) (5 µl) and 5 µl universal PCR primer (•) to each PCR tube. It is critical to change tips between tubes to avoid cross-contamination.
  3. Record the index 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 ChIP 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).

APPENDIX: Quality Control of the Kit Components

The components in the SimpleChIP® ChIP-seq Multiplex Oligos for Illumina® (Single Index Primers) #29580 are individually validated by the functional testing listed below and must pass rigorous quality control standards. Furthermore, each set of components is functionally validated together by construction and sequencing of indexed libraries on the Illumina® sequencing platform.

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 Reslase Using Nuclease (CUT&RUN) assays to identify and quantify target DNA enrichment across the entire genome. Multiplex Oligos for Illumina® (Single Index Primers) (ChIP-seq, CUT&RUN) contains adaptors and primers that are ideally suited for multiplex sample preparation for NG-seq on the Illumina® platform. This kit can be used to generate up to 12 distinct, barcoded ChIP-seq or CUT&RUN DNA libraries that can be combined into a single sequencing reaction.

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® (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 similiar Bioanalyzer® profiles, genome mapping rates, numbers of identified binding peaks, 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).
