CST CUT&RUN Kit: Validated for Flexibility

Same Kit, More Flexibility

The Cleavage Under Targets & Release Using Nuclease (CUT&RUN) assay is a faster, more cost-effective alternative to ChIP-qPCR and ChIP-seq that requires fewer cells to investigate protein-DNA interactions. Cell Signaling Technology^® (CST^®) has made its CUT&RUN Kit even better by performing additional validation and optimization to improve the protocol, resulting in even more options for how you explore protein-DNA interactions.

New Expanded Benefits

CUT&RUN is an in vivo method that delivers results in 1-2 days, lowers sequencing costs, and is compatible with a variety of antibodies and targets. The CUT&RUN Assay Kit now offers these additional benefits to increase assay flexibility:

Better Data with an Improved Protocol

Continued development on the CUT&RUN protocol has further optimized the protocol to enhance your data and validated the CUT&RUN Assay Kit for use with a wider variety of sample types. For example, we now recommend performing digestions at 4°C instead of 0°C to facilitate the recovery of targeted chromatin fragments without significantly increasing background. This improves qPCR and NG-seq analysis, especially for transcription factors and cofactors.

Panel A

Panel B

CUT&RUN was performed with NCCIT cells and SUZ12 (D39F6) XP® Rabbit mAb #3737, using CUT&RUN Assay Kit #86652. DNA was digested at either 0°C or 4°C as indicated. In panel A, the enriched DNA was quantified by real-time PCR using SimpleChIP^® Human HoxA1 Intron 1 Primers #7707, SimpleChIP^® Human HoxA2 Promoter Primers #5517, and SimpleChIP^® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one. In panel B, DNA Libraries were prepared using DNA Library Prep Kit for Illumina (ChIP-seq, CUT&RUN) #56795. The figure shows binding across HoxA genes.

Save Time by Using 5-20x Less Sample

CUT&RUN already required significantly fewer cells to generate reliable data compared to ChIP-qPCR and ChIP-seq, and CST has further increased your time savings by optimizing protocols to use even less sample.

Unable to collect 100K cells, but still want to perform CUT&RUN? Not a problem as you can generate the same great data with just 5-20K cells.

Study Protein-DNA Interactions in Tissue Samples with Confidence

The high sample input required to perform ChIP experiments is extremely restrictive when it comes to profiling chromatin in limited sample types like tissue. The sample savings CUT&RUN delivers for cultured cells extends to tissue samples. Depending on the tissue, ChIP can require anywhere from 25 to 50 mg of tissue while our CUT&RUN kit now only requires approximately 1 to 2.5 mg depending on the tissue type.

Validated protocols give you confidence in your data even when using ~20x less sample to explore protein-DNA interactions using the CST CUT&RUN Assay Kit #86652.

Profile Chromatin in Primary Cells

Before CUT&RUN, analyzing protein-DNA interactions in primary cells, which aren’t immortalized, with ChIP was nearly impossible due to the challenges involved with trying to grow up enough cells.

The CUT&RUN Assay Kit #86652 significantly lowers the cell number requirement, making studying protein-DNA interactions in primary cells feasible. Don’t compromise your desired sample type just to meet cell number requirements.

CUT&RUN was performed with 100,000 live human CD8+ T cells and Tri-Methyl-Histone H3 (Lys4) (C42D8) Rabbit mAb #9751 or CTCF (D31H2) XP^® Rabbit mAb #3418, using CUT&RUN Assay Kit #86652.
