NAIP6 CRISPR/Cas9 KO Plasmid (m): sc-421819

Overview

Naip6 encodes neuronal apoptosis inhibitory protein 6 (NAIP6), a member of the NLR family of intracellular innate immune sensors that regulate inflammasome-linked signaling and cell death pathways. NAIP proteins recognize select bacterial ligands and can cooperate with NLRC4 to promote caspase-1 activation, cytokine maturation, and pyroptotic responses, linking pathogen sensing to inflammatory homeostasis. In mouse models, NAIP-related pathways have been used to study host–microbe interactions, epithelial and myeloid defense programs, and dysregulated inflammation. Altered inflammasome activity is broadly relevant to inflammatory tissue injury and immune-mediated disease mechanisms, making Naip6 useful for dissecting pathway-specific contributions in vivo and in cultured mouse cells.

NAIP6 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Naip6 gene in mouse cell lines. Each plasmid in the pool co-expresses a unique sgRNA, targeting a distinct site within the Naip6 locus, alongside the Streptococcus pyogenes Cas9 nuclease, and encodes GFP to enable fluorescent identification and enrichment of successfully transfected cells. This multi-guide strategy increases the likelihood of inducing frameshifts or deletions that produce a functional knockout, offering a more robust alternative to single-guide approaches. DSBs induced at multiple sites are resolved through non-homologous end joining (NHEJ) or, when used with the included HDR donor template, homology-directed repair (HDR) at a defined target site within the locus.

When used in conjunction with the RFP-expressing HDR donor, GFP and RFP fluorescence can be used together to distinguish transfected from edited cell populations, streamlining flow cytometry-based sorting and clone selection workflows.

Homology-Directed Repair (HDR) Donor — Puromycin Cassette with RFP Reporter

For applications requiring confirmed, selectable knockout clones, NAIP6 HDR Plasmid (m) includes an HDR donor construct containing a puromycin resistance cassette (PuroR) and a red fluorescent protein (RFP) reporter, flanked by homology arms specific to a defined Naip6 target site.
When co-transfected with NAIP6 CRISPR/Cas9 KO Plasmid (m):

• The PuroR-RFP cassette integrates at the Cas9 cut site via HDR, disrupting the Naip6 open reading frame.
• RFP fluorescence provides an immediate visual indicator of successful integration, enabling fluorescence-based identification or sorting of edited cells prior to or alongside puromycin selection.
• Successfully edited cells are confirmed through puromycin resistance, substantially reducing clone screening burden.
• This selection strategy is ideal for generating stable, clonal KO cell lines for downstream functional studies, drug screening, or model development.

Cre-lox Cassette Removal System

The HDR donor construct features loxP sites flanking the PuroR-RFP selection cassette to allow clean marker removal following clone confirmation. Transient expression of Cre recombinase via the included Cre Vector: sc-418923 excises the cassette, leaving a minimal residual loxP site within the Naip6 locus and eliminating potential confounding effects on downstream assays.
This two-step approach:

• Minimizes disruption to local chromatin architecture and neighboring regulatory elements
• Restores a near-native genomic context at the edited locus
• Enables reuse of the puromycin selection strategy in the same cell line for additional edits
