Aldehyde dehydrogenase 1B1/ALDH1B1 Double Nickase Plasmid (h): sc-404562-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Aldehyde dehydrogenase 1B1/ALDH1B1 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
- Aldehyde dehydrogenase 1B1/ALDH1B1 Double Nickase Plasmid (h) and Aldehyde dehydrogenase 1B1/ALDH1B1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting ALDH1B1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Aldehyde dehydrogenase 1B1/ALDH1B1 Antibody (G-2): sc-393583

Human ALDH1B1 encodes a mitochondrial aldehyde dehydrogenase that oxidizes a broad range of endogenous and xenobiotic aldehydes to their corresponding carboxylic acids using NAD(P)+, supporting cellular redox balance and aldehyde detoxification. By limiting accumulation of reactive aldehydes generated during lipid peroxidation and intermediary metabolism, ALDH1B1 contributes to mitochondrial homeostasis and protection from carbonyl stress. Its activity intersects with ethanol/acetaldehyde handling, retinoid-related aldehyde metabolism, and oxidative stress response pathways that influence proliferation, differentiation, and metabolic adaptation. Altered ALDH1B1 expression and ALDH enzymatic programs have been associated with tumor biology and metabolic phenotypes, motivating functional interrogation in models of cancer, inflammation, and mitochondrial dysfunction.
Aldehyde dehydrogenase 1B1/ALDH1B1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ALDH1B1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ALDH1B1. 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 ALDH1B1 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 ALDH1B1-disrupted clones.
