SPT6 Double Nickase Plasmid (h) | sc-406219-NIC | 20 µg | $410.00 |
SUPT6H encodes SPT6, a conserved histone chaperone and transcription elongation factor that associates with RNA polymerase II to coordinate nucleosome reassembly and preserve chromatin integrity during transcription. By interacting with factors such as the PAF1 complex and regulating histone modification patterns, SPT6 links transcriptional elongation to co-transcriptional RNA processing and epigenetic maintenance. This activity supports global gene expression programs that govern cell identity, proliferation, and stress responses. Dysregulation of SPT6-dependent chromatin control has been implicated in aberrant transcriptional states observed in cancer and other disorders of transcription and genome regulation.
SPT6 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SUPT6H locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SUPT6H. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt SUPT6H function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of SUPT6H-disrupted clones.
