α-S1-casein CRISPR/Cas9 KO Plasmid (m): sc-419847
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- α-S1-casein 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 α-S1-casein 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: α-S1-casein Antibody (D-12): sc-365929

Overview
Csn1s1 encodes mouse α-S1-casein, a major secreted phosphoprotein of milk that is synthesized by differentiated mammary epithelial cells and packaged for export through the ER–Golgi secretory pathway. As a core component of casein micelles, α-S1-casein contributes to micellar assembly and calcium/phosphate handling, supporting efficient nutrient delivery during lactation. Csn1s1 expression is strongly regulated by lactogenic hormones and downstream JAK2/STAT5 and prolactin-responsive transcriptional programs that coordinate mammary gland differentiation. Altered casein gene regulation is used as a readout of mammary epithelial cell state, secretory stress responses, and lactation-associated phenotypes relevant to breast biology research models.
α-S1-casein CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Csn1s1 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Csn1s1 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 Csn1s1 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 α-S1-casein protein expression.
This CRISPR knockout system enables efficient generation of Csn1s1-deficient cell models for investigation of α-S1-casein signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by α-S1-casein CRISPR/Cas9 KO Plasmid (m) and α-S1-casein CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Csn1s1 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by α-S1-casein HDR Plasmid (m) and α-S1-casein HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Csn1s1 homology arms to support homology-directed repair at defined Csn1s1 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
