pA-Tn5 Transposase is a fusion protein of hyperactive Tn5 transposase and protein A developed for the CUT&Tag assay. For ease of use, the fusion protein is pre-loaded with sequencing adapters suitable for single or dual indexing in single or paired-end Illumina platforms. The adaptors contain 19-mer Tn5 mosaic ends and the sequences for PCR amplification with barcoded i7/i5.
