Zap-70 CRISPR/Cas9 KO Plasmid (h): sc-400826
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Zap-70 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 Zap-70 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: ZAP-70 Antibody (1E7.2): sc-32760

Overview
ZAP70 encodes Zap-70, a cytoplasmic tyrosine kinase essential for proximal T cell receptor (TCR) signaling downstream of CD3/ζ chain phosphorylation by LCK. Upon recruitment to phosphorylated ITAMs, Zap-70 phosphorylates adaptor proteins such as LAT and SLP-76, coordinating assembly of signalosomes that propagate PLCγ1 activation, Ca²⁺ flux, MAPK cascades, NF-κB/NFAT transcriptional programs, and cytoskeletal remodeling. These pathways control thymocyte selection, T cell activation, differentiation, and effector functions, linking ZAP70 activity to immune homeostasis. Altered ZAP70 expression or signaling dynamics has been associated with immunodeficiency phenotypes and dysregulated lymphocyte activation observed in autoimmune and hematologic disease contexts.
Zap-70 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the ZAP70 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the ZAP70 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 ZAP70 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 Zap-70 protein expression.
This CRISPR knockout system enables efficient generation of ZAP70-deficient cell models for investigation of Zap-70 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Zap-70 CRISPR/Cas9 KO Plasmid (h) and Zap-70 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the ZAP70 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Zap-70 HDR Plasmid (h) and Zap-70 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by ZAP70 homology arms to support homology-directed repair at defined ZAP70 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
