Fibulin-1 CRISPR/Cas9 KO Plasmid (h): sc-401754
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Fibulin-1 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 Fibulin-1 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: Fibulin-1 Antibody (B-5): sc-25281

Overview
FBLN1 encodes fibulin-1, a secreted extracellular matrix glycoprotein that associates with basement membranes and elastic fiber–rich matrices, supporting tissue architecture and cell–matrix communication. Fibulin-1 interacts with multiple ECM components to influence cell adhesion, migration, and mechanotransduction, linking matrix organization to signaling programs that regulate proliferation and differentiation. Through these functions, FBLN1 contributes to vascular and connective tissue homeostasis and is frequently examined in remodeling contexts such as fibrosis, inflammation-associated stromal changes, and tumor microenvironment evolution. Altered fibulin-1 expression or deposition has been reported across cardiovascular and cancer-related studies, motivating mechanistic work on ECM-driven phenotypes and matrix-dependent signaling.
Fibulin-1 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the FBLN1 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the FBLN1 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 FBLN1 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 Fibulin-1 protein expression.
This CRISPR knockout system enables efficient generation of FBLN1-deficient cell models for investigation of Fibulin-1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Fibulin-1 CRISPR/Cas9 KO Plasmid (h) and Fibulin-1 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the FBLN1 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Fibulin-1 HDR Plasmid (h) and Fibulin-1 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by FBLN1 homology arms to support homology-directed repair at defined FBLN1 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
