Integrin β2/ITGB2/CD18 Double Nickase Plasmid (h): sc-400921-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Integrin β2/ITGB2/CD18 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
- Integrin β2/ITGB2/CD18 Double Nickase Plasmid (h) and Integrin β2/ITGB2/CD18 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting ITGB2. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Integrin β2/ITGB2/CD18 Antibody (CTB104): sc-8420

ITGB2 encodes integrin β2 (CD18), a leukocyte-restricted adhesion receptor subunit that pairs with α chains (e.g., ITGAL/CD11a, ITGAM/CD11b, ITGAX/CD11c) to form β2 integrins that control immune cell trafficking and effector functions. These heterodimers regulate firm adhesion to endothelium, transendothelial migration, and immunological synapse formation through outside-in and inside-out signaling linked to cytoskeletal remodeling, focal adhesion dynamics, and MAPK/PI3K-associated pathways. CD18-dependent interactions with ICAM family ligands coordinate neutrophil and lymphocyte recruitment during inflammation and shape phagocytosis and oxidative burst programs. Genetic or functional perturbation of ITGB2 is associated with leukocyte adhesion defects and altered inflammatory responses, making it a key target for studying host defense and immune dysregulation mechanisms.
Integrin β2/ITGB2/CD18 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ITGB2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ITGB2. 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 ITGB2 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 ITGB2-disrupted clones.
