fibrillin-2 CRISPR/Cas9 KO Plasmid (h): sc-406714
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- fibrillin-2 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 fibrillin-2 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: fibrillin-2 Antibody (H-10): sc-393968

Overview
FBN2 encodes fibrillin-2, a large extracellular matrix glycoprotein that polymerizes into microfibrils and contributes to elastic fiber assembly and connective tissue architecture. Fibrillin-2–containing microfibrils provide structural support and regulate growth factor bioavailability, influencing signaling pathways such as TGF-β and BMP that govern morphogenesis and tissue homeostasis. Through interactions with integrins and matrix-associated proteins, fibrillin-2 modulates cell adhesion, mechanotransduction, and extracellular matrix remodeling. Genetic perturbation of FBN2 is associated with congenital connective tissue phenotypes, making it relevant for studies of developmental matrix biology and dysregulated growth factor signaling.
fibrillin-2 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the FBN2 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the FBN2 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 FBN2 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 fibrillin-2 protein expression.
This CRISPR knockout system enables efficient generation of FBN2-deficient cell models for investigation of fibrillin-2 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by fibrillin-2 CRISPR/Cas9 KO Plasmid (h) and fibrillin-2 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the FBN2 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by fibrillin-2 HDR Plasmid (h) and fibrillin-2 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by FBN2 homology arms to support homology-directed repair at defined FBN2 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
