Fibulin-1 Double Nickase Plasmid (h): sc-401754-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Fibulin-1 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
- Fibulin-1 Double Nickase Plasmid (h) and Fibulin-1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting FBLN1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Fibulin-1 Antibody (B-5): sc-25281

FBLN1 encodes fibulin-1, a secreted extracellular matrix glycoprotein that associates with elastic fibers, basement membrane components, and multiple proteoglycans to influence matrix organization and tissue mechanics. Fibulin-1 participates in cell–matrix adhesion and remodeling processes that intersect with integrin-linked signaling, wound repair programs, and vascular extracellular matrix homeostasis. Altered FBLN1 expression and matrix deposition have been reported in fibrosis and cardiovascular remodeling contexts, and dysregulated extracellular matrix architecture is also implicated in tumor microenvironment biology. As a result, FBLN1 is frequently studied as a structural and regulatory node connecting extracellular matrix assembly to cell migration, proliferation, and mechanotransduction.
Fibulin-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the FBLN1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within FBLN1. 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 FBLN1 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 FBLN1-disrupted clones.
