简单描述

The CUT&RUN Assay Kit is designed to conveniently provide reagents needed to perform up to 8 (P size) or 24 (S size) digestion reactions from cells and is optimized for 100,000 cells per reaction. The kit has been optimized to work for all types of DNA binding proteins, including histones, transcription factors and cofactors. A complete assay can be performed in as little as one day.

The CUT&RUN Assay Kit also provides important controls to ensure a successful CUT&RUN experiment. The kit contains a positive control Tri-Methyl-Histone H3 (Lys4) (C42D8) Rabbit mAb #9751 and a negative control Rabbit (DA1E) mAb IgG XP® Isotype Control (CUT&RUN) #66362, both of which can be used for qPCR or Next Generation sequencing (NG-seq) analysis. PCR primer sets are provided for the human (#7014) and mouse (#7015) RPL30 gene locus to be used in conjunction with the control antibodies. This kit is compatible with both qPCR and NG-seq.

Specificity/Sensitivity

The CUT&RUN Assay Kit can be utilized with any CUT&RUN-validated antibody to detect endogenous levels of protein-DNA interactions and histone modifications in mammalian cells (see Figures 1–6). The kit is compatible with multiple species of antibodies, including rabbit and mouse. The positive control Tri-Methyl-Histone H3 (Lys4) (C42D8) Rabbit mAb #9751 detects multiple species of tri-methyl histone H3 Lys4 protein, including human, mouse, rat, and monkey. Primer sets are included for the human (#7014) and mouse (#7015) positive control RPL30 gene locus; however, the use of other species with the kit requires the design of additional control primer sets.

背景
背景
Like the chromatin immunoprecipitation (ChIP) assay, Cleavage Under Targets & Release Using Nuclease (CUT&RUN) is a powerful and versatile technique used for probing protein-DNA interactions within the natural chromatin context of the cell (1-4). 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 associated with a particular protein. In addition, the CUT&RUN assay can be used to define the spatial and temporal relationship of a particular protein-DNA interaction. For example, the CUT&RUN assay can be used to determine the specific order of recruitment of various protein factors to a gene promoter or to “measure” the relative amount of a particular histone modification across an entire gene locus during gene activation. In addition to histone proteins, the CUT&RUN assay can also be used to analyze binding of transcription factors and cofactors, DNA replication factors, and DNA repair proteins (Figures 1-6).CUT&RUN provides a rapid, robust, and true low cell number assay for detection of protein-DNA interactions in the cell. Unlike the ChIP assay, CUT&RUN is free from formaldehyde cross-linking, chromatin fragmentation, and immunoprecipitation, making it a much faster and more efficient method for enriching protein-DNA interactions and identifying target genes. CUT&RUN can be performed in less than one day, from live cells to purified DNA, and has been shown to work with as few as 500-1000 cells per assay (1,2). Instead of fragmenting all of the cellular chromatin as done in ChIP, CUT&RUN utilizes an antibody-targeted digestion of chromatin, resulting in much lower background signal than seen in the ChIP assay. As a result, CUT&RUN requires only 1/10th of the sequencing depth that is required for ChIP-seq assays (1,2). Finally, the inclusion of simple spike-in control DNA allows for accurate quantification and normalization of target-protein binding that is not possible with the ChIP method. This provides for effective normalization of signal between samples and between experiments. 1.Skene, P.J. and Henikoff, S. (2017) Elife 6, pii: e21856. doi: 10.7554/eLife.21856. 2.Skene, P.J. et al.

Figure 12. CUT&RUN and ChIP assays were performed with HeLa cells and Rpb1 CTD (4H8) Mouse mAb #2629, using this CUT&RUN Assay Kit or the SimpleChIP® Plus Enzymatic Chromatin IP Kit (Magnetic Beads) #9005. DNA Libraries were prepared using DNA Library Prep Kit for Illumina® (ChIP-seq, CUT&RUN) #56795. The upper panel compares enrichment of Rpb1 across chromosome 12, while the lower panel compares enrichment at the GAPDH gene, a known target of Rbp1. The input tracks are from the CUT&RUN input sample.
