Factor VII CRISPR Activation Plasmid (h) | sc-402582-ACT | 20 µg | $397.00 |
Human F7 encodes coagulation factor VII, a vitamin K–dependent serine protease zymogen synthesized primarily in hepatocytes and secreted into plasma. Upon binding tissue factor (F3) at sites of vascular injury, activated factor VIIa initiates the extrinsic coagulation cascade by proteolytically activating factor X (F10) and factor IX (F9), amplifying thrombin generation and fibrin formation. This pathway intersects with endothelial and platelet biology and can signal through protease-activated receptors (PARs) to influence vascular inflammation and hemostatic balance. Dysregulated F7 activity or expression is associated with bleeding phenotypes and thrombotic risk, making it a relevant target for studying coagulation pathway regulation and genotype–phenotype relationships.
Factor VII CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous F7 expression without altering the underlying DNA sequence.
Factor VII CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the F7 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the F7 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Factor VII expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native F7 locus and enabling the study of Factor VII-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Factor VII pathway restoration in tumor cells with silenced or reduced F7 expression.
