Progesterone Receptor Double Nickase Plasmid (h): sc-400198-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Progesterone Receptor Double Nickase Plasmid (h) consists of a pair of plasmids each encoding a D10A mutated Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed to knockout gene expression with greater specificity than its CRISPR/Cas9 KO counterpart
- Paired gRNA sequences are offset by approximately 20 bp to allow for specific Cas9-mediated double nicking of the genomic DNA, which mimics a DSB
- One plasmid in the pair contains a puromycin-resistance gene for selection; the other plasmid in the pair contains a GFP marker to visually confirm transfection
- Progesterone Receptor Double Nickase Plasmid (h) and Progesterone Receptor Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting PGR. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Progesterone Receptor Antibody (F-4): sc-166169

PGR encodes the human progesterone receptor, a ligand-activated nuclear transcription factor that regulates gene programs controlling reproductive tissue development, decidualization, and endocrine-responsive cell proliferation and differentiation. Upon progesterone binding, PGR engages hormone response elements and coregulators to modulate chromatin and transcription, while also intersecting with MAPK/ERK, PI3K/AKT, and crosstalk with estrogen receptor signaling to shape cell-cycle and inflammatory responses. Altered PGR expression, isoform balance, or signaling output is implicated in hormone-dependent biology and is frequently studied in contexts such as breast and endometrial cancer, endometriosis, uterine fibroids, and infertility. These features make PGR a central node for investigating steroid receptor transcriptional networks and endocrine regulation in human cell models.
Progesterone Receptor Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the PGR locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within PGR. 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 PGR 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 PGR-disrupted clones.
