TRIM7 CRISPR/Cas9 KO Plasmid (m): sc-430107
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- TRIM7 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 TRIM7 genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- TRIM7 HDR Plasmid (m) (sc-430107-HDR) is recommended for co-transfection with TRIM7 CRISPR/Cas9 KO Plasmid (m) to enable selection of successfully edited cells through HDR-mediated integration of a puromycin resistance cassette and RFP reporter gene
- TRIM7 HDR Plasmid (m) is a pool of plasmids, each containing a homology-directed repair (HDR) template corresponding to the gRNA target sites in the TRIM7 CRISPR/Cas9 KO Plasmid (m)
- Each HDR plasmid contains two ~800 bp homology arms flanking the puromycin resistance and RFP cassettes, designed to bind genomic DNA sequences surrounding the Cas9-induced double-strand break site and facilitate precise HDR-mediated integration
- 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

Overview
Trim7 encodes TRIM7, a tripartite motif (TRIM) family E3 ubiquitin ligase that helps regulate protein stability and signaling output through ubiquitin-dependent pathways. TRIM7 is implicated in control of proteostasis, modulation of innate immune signaling, and coordination of cellular stress responses via regulation of substrate turnover and downstream transcriptional programs. Through its ubiquitin ligase activity, TRIM7 can influence pathways linked to inflammation, metabolism, and cell fate decisions, making it relevant for studying mechanisms that contribute to immune dysregulation and other complex disease phenotypes. In mouse systems, Trim7 provides a tractable genetic node for dissecting how ubiquitin-mediated regulation shapes tissue homeostasis and stimulus-responsive signaling.
TRIM7 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Trim7 gene in mouse cell lines. Each plasmid in the pool co-expresses a unique sgRNA, targeting a distinct site within the Trim7 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, TRIM7 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 Trim7 target site.
When co-transfected with TRIM7 CRISPR/Cas9 KO Plasmid (m):
- The PuroR-RFP cassette integrates at the Cas9 cut site via HDR, disrupting the Trim7 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 Trim7 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
