PDI CRISPR/Cas9 KO Plasmid (m) | sc-422099 | 20 µg | $397.00 |
P4hb encodes protein disulfide isomerase (PDI), an abundant endoplasmic reticulum oxidoreductase that catalyzes disulfide bond formation, reduction, and isomerization to support folding and maturation of secretory and membrane proteins. PDI functions in ER proteostasis networks, partnering with chaperones and oxidoreductases to regulate oxidative protein folding and quality control, and it contributes to ER stress signaling and unfolded protein response pathways. Through its thiol-disulfide exchange activity and interactions with misfolded substrates, PDI influences redox homeostasis, protein trafficking, and cell survival decisions under proteotoxic stress. Dysregulated P4hb/PDI activity has been linked to pathological states characterized by chronic ER stress and altered redox balance, making it a relevant target for mechanistic studies in neurodegeneration, metabolic dysfunction, and cancer biology models.
PDI CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the P4hb gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the P4hb 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 P4hb 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 PDI protein expression.
This CRISPR knockout system enables efficient generation of P4hb-deficient cell models for investigation of PDI signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.
