ERp57 CRISPR/Cas9 KO Plasmid (m): sc-420698
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- ERp57 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 ERp57 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: ERp57 Antibody (MaP.ERp57): sc-23886

Overview
Pdia3 encodes ERp57 (also known as PDIA3/GRP58), an endoplasmic reticulum thiol–disulfide oxidoreductase that partners with calnexin and calreticulin to promote oxidative folding and quality control of nascent glycoproteins. ERp57 supports ER proteostasis through disulfide bond formation and is closely linked to unfolded protein response signaling, ER-associated degradation, and redox homeostasis. Beyond the ER lumen, PDIA3 has been implicated in antigen presentation via MHC class I peptide loading and in modulation of signaling pathways connected to cellular stress adaptation. Dysregulation of PDIA3/ERp57 activity is associated with conditions characterized by proteotoxic and oxidative stress, including neurodegenerative and metabolic disease models, making it relevant for mechanistic studies of ER stress and immune-related processes.
ERp57 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Pdia3 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Pdia3 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 Pdia3 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 ERp57 protein expression.
This CRISPR knockout system enables efficient generation of Pdia3-deficient cell models for investigation of ERp57 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by ERp57 CRISPR/Cas9 KO Plasmid (m) and ERp57 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Pdia3 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by ERp57 HDR Plasmid (m) and ERp57 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Pdia3 homology arms to support homology-directed repair at defined Pdia3 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
