RecQL1 Double Nickase Plasmid (m) | sc-422636-NIC | 20 µg | $410.00 |
Recql encodes the mouse RecQL1 DNA helicase, a member of the RecQ family that preserves genome integrity during DNA replication and repair. RecQL1 participates in replication fork restart, processing of DNA secondary structures, and resolution of recombination intermediates, linking its activity to homologous recombination and replication stress responses. Through interactions with core repair factors and DNA metabolism enzymes, RecQL1 helps limit chromosomal breaks and aberrant sister chromatid exchanges. Altered RecQL1 function is associated with genomic instability phenotypes that are widely used to model mechanisms relevant to cancer biology and other disorders driven by defective DNA damage responses.
RecQL1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Recql locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Recql. 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 Recql 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 Recql-disrupted clones.
