The CUT&Tag-IT™ assay kit from Active Motif enables rapid and robust genome-wide analysis of histone marks and transcription factor binding using in as few as 5,000 cells, making it ideal for researchers with limited samples. With no need for cell fixation and no artifacts caused from formaldehyde crosslinking, this CUT&Tag method produces high-quality, sequencing-ready libraries without the laborious and costly steps of ChIP-Seq.
Benefits of using the CUT&Tag-IT assay kit
• Compatible with as few as 5,000 cells
• Genome-wide analysis of histone marks and transcription factor binding
• Sequencing-ready libraries produced
• Low background signal for lower sequencing depth
• No artifacts caused by formaldehyde crosslinking
• Provided as a complete kit with optimised protocol
Please note that for researchers interested in understanding genome-wide transcription factor recruitment (endogenous or tagged), ChIP-seq is still recommended. Explore the range of ChIP-seq assay kits from Active Motif.
