Set1B CRISPR/Cas9 KO Plasmid (h): sc-406129
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Set1B 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 Set1B 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

Overview
SETD1B encodes the Set1B lysine methyltransferase, a catalytic component of COMPASS-like chromatin-modifying complexes that deposit H3K4 methylation marks associated with transcriptionally active chromatin. Through regulation of promoter and enhancer states, Set1B contributes to RNA polymerase II–dependent gene expression programs that influence cell identity, proliferation, and differentiation. SETD1B activity intersects with broader epigenetic pathways governing chromatin accessibility and DNA damage responses by shaping histone modification landscapes. Genetic variation and dysregulation of SETD1B have been linked to neurodevelopmental phenotypes and altered transcriptional control, making it a relevant target for mechanistic studies of gene regulation in human cells.
Set1B CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the SETD1B gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the SETD1B 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 SETD1B 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 Set1B protein expression.
This CRISPR knockout system enables efficient generation of SETD1B-deficient cell models for investigation of Set1B signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Set1B CRISPR/Cas9 KO Plasmid (h) and Set1B CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the SETD1B locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Set1B HDR Plasmid (h) and Set1B HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by SETD1B homology arms to support homology-directed repair at defined SETD1B target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
