Orexin-A/B CRISPR/Cas9 KO Plasmid (m): sc-420816
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Orexin-A/B CRISPR/Cas9 Knockout (KO) Plasmid (m) is a pool of plasmids, each encoding Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed for maximum knockout efficiency using sequences derived from the GeCKO v2 library
- gRNA sequences direct Cas9 to induce site-specific double-strand breaks (DSBs) in the Orexin-A/B genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- The puromycin resistance and RFP genes are flanked by LoxP sites, enabling removal of selection markers via Cre recombinase (Cre Vector: sc-418923) after establishing stable knockout cell lines
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Orexin-A Antibody (KK09): sc-80263

Overview
Mouse Hcrt encodes the neuropeptides orexin-A and orexin-B (hypocretins), which are produced by a restricted population of hypothalamic neurons and signal primarily through the GPCRs OX1R and OX2R. Orexin signaling promotes arousal and wake maintenance, integrates energy balance with feeding behavior, and modulates reward and stress responses via coupling to intracellular Ca2+ mobilization, MAPK signaling, and broader neuroendocrine circuits. These peptides influence autonomic output and sleep–wake transitions by shaping excitatory drive across monoaminergic and cholinergic pathways. Dysregulated orexin function is strongly linked to sleep–wake instability and metabolic phenotypes, making Hcrt a key node for mechanistic studies of neural state control.
Orexin-A/B CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Hcrt gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Hcrt together with the Streptococcus pyogenes Cas9 nuclease. The plasmids also encode GFP, allowing fluorescent identification and enrichment of successfully transfected cells by fluorescence microscopy or flow cytometry.
The multi-guide design increases the likelihood of generating insertions or deletions (indels) that disrupt the Hcrt open reading frame following Cas9-mediated double-strand break formation. DNA breaks introduced by the CRISPR/Cas9 system are repaired through endogenous non-homologous end joining (NHEJ) pathways, frequently resulting in frameshift mutations that abolish Orexin-A/B protein expression.
This CRISPR knockout system enables efficient generation of Hcrt-deficient cell models for investigation of Orexin-A/B signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Orexin-A/B CRISPR/Cas9 KO Plasmid (m) and Orexin-A/B CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Hcrt locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Orexin-A/B HDR Plasmid (m) and Orexin-A/B HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Hcrt homology arms to support homology-directed repair at defined Hcrt target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
