Hrs CRISPR/Cas9 KO Plasmid (r): sc-437306
- Target species: rat
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Hrs CRISPR/Cas9 Knockout (KO) Plasmid (r) 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 Hrs 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

Overview
Hrs (hepatocyte growth factor–regulated tyrosine kinase substrate; also known as HGS) is an endosomal sorting protein that functions within the ESCRT-0 complex to recognize ubiquitinated membrane proteins and direct their trafficking into multivesicular bodies for lysosomal degradation. By coordinating endosomal maturation and receptor downregulation, Hrs influences signaling outputs from receptor tyrosine kinases and other surface receptors, shaping pathways that control proliferation, differentiation, and stress responses. This protein is integral to membrane protein turnover, endosome-to-lysosome transport, and proteostasis, processes frequently examined in studies of neurodegeneration, inflammation, and oncogenic signaling dysregulation. In rat systems, perturbing Hrs supports mechanistic research into how altered endosomal sorting affects receptor fate decisions and downstream pathway rewiring.
Hrs CRISPR/Cas9 KO Plasmid (r) is a pool of plasmids designed for targeted disruption of the gene in rat cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the 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 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 Hrs protein expression.
This CRISPR knockout system enables efficient generation of -deficient cell models for investigation of Hrs signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Hrs CRISPR/Cas9 KO Plasmid (r) and Hrs CRISPR/Cas9 KO Plasmid (r2) target distinct sites within the locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Hrs HDR Plasmid (r) and Hrs HDR Plasmid (r2) contain a puromycin resistance cassette and an RFP reporter flanked by homology arms to support homology-directed repair at defined target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
