galectin-4 CRISPR/Cas9 KO Plasmid (h): sc-404255
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- galectin-4 CRISPR/Cas9 Knockout (KO) Plasmid (h) 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 galectin-4 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: galectin-4 Antibody (D-11): sc-376398

Overview
LGALS4 encodes galectin-4, a β-galactoside–binding lectin enriched in gastrointestinal epithelia that contributes to apical membrane organization and mucosal barrier homeostasis. Galectin-4 engages glycosylated receptors and extracellular matrix components to regulate cell–cell and cell–matrix adhesion, epithelial polarity, and differentiation. Through glycan-dependent interactions, it can influence signaling nodes linked to inflammation and epithelial remodeling, including pathways coordinating adhesion dynamics and cytokine responses. Dysregulated LGALS4 expression has been associated with intestinal inflammatory states and epithelial neoplasia, supporting its use as a functional marker in studies of barrier disruption and tumor biology.
galectin-4 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the LGALS4 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the LGALS4 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 LGALS4 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 galectin-4 protein expression.
This CRISPR knockout system enables efficient generation of LGALS4-deficient cell models for investigation of galectin-4 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by galectin-4 CRISPR/Cas9 KO Plasmid (h) and galectin-4 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the LGALS4 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by galectin-4 HDR Plasmid (h) and galectin-4 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by LGALS4 homology arms to support homology-directed repair at defined LGALS4 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
