PAPP-A CRISPR/Cas9 KO Plasmid (h): sc-406222
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- PAPP-A 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 PAPP-A 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: PAPP-A Antibody (B-7): sc-365226

Overview
PAPPA encodes pregnancy-associated plasma protein A (PAPP-A), a secreted metalloproteinase of the pappalysin family that regulates insulin-like growth factor (IGF) bioavailability by cleaving IGF-binding proteins, particularly IGFBP4 and IGFBP5. By increasing local free IGF, PAPP-A modulates IGF1R-driven signaling pathways such as PI3K–AKT and MAPK/ERK, influencing cell proliferation, differentiation, and survival in tissue remodeling contexts. PAPP-A activity is also linked to extracellular matrix–proximal proteolysis and paracrine regulation of growth factor signaling in vascular and stromal microenvironments. Dysregulated PAPPA expression or activity has been associated with placental biology, atherosclerotic plaque biology, and inflammatory cardiometabolic phenotypes, motivating mechanistic studies of IGF axis control in disease-relevant cell types.
PAPP-A CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the PAPPA gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the PAPPA 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 PAPPA 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 PAPP-A protein expression.
This CRISPR knockout system enables efficient generation of PAPPA-deficient cell models for investigation of PAPP-A signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

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