TTP Double Nickase Plasmid (m) | sc-423781-NIC | 20 µg | $410.00 |
Mouse Zfp36 encodes tristetraprolin (TTP), an AU-rich element–binding RNA-binding protein that promotes deadenylation and decay of labile mRNAs, including many cytokine and immediate-early transcripts. By recruiting the CCR4–NOT deadenylase complex and modulating post-transcriptional gene regulation, TTP shapes inflammatory signaling outputs downstream of pathways such as TNF/NF-κB and MAPK/p38. Altered Zfp36/TTP activity is linked to dysregulated cytokine homeostasis and inflammatory phenotypes, and is frequently studied in the context of immune cell activation, macrophage responses, and stress-induced transcript remodeling. As a node in mRNA turnover networks, TTP provides a tractable entry point for dissecting how RNA stability controls gene expression programs relevant to inflammation-associated pathology.
TTP Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Zfp36 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Zfp36. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt Zfp36 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of Zfp36-disrupted clones.
