C7 CRISPR Activation Plasmid (h): sc-404773-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- C7 CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- C7 CRISPR Activation Plasmid (h) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by C7 CRISPR Activation Plasmid (h) and C7 CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the C7 transcriptional start site. One or both designs may be available

Complement component 7 (C7) encodes a terminal complement protein that assembles with C5b, C6, C8, and C9 to form the membrane attack complex (MAC), a pore-forming effector of innate immunity. Through activation of the classical, lectin, or alternative complement pathways, C7 contributes to pathogen lysis, clearance of immune complexes, and modulation of inflammatory signaling at cell surfaces. Dysregulated complement activity, including aberrant terminal pathway engagement, is implicated in inflammatory and autoimmune pathology and has been investigated in settings such as infection susceptibility and complement-mediated tissue injury. In addition to antimicrobial defense, MAC formation can influence cell stress responses and cytokine production, linking C7 biology to broader immune homeostasis.
C7 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous C7 expression without altering the underlying DNA sequence.
C7 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the C7 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 C7 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous C7 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native C7 locus and enabling the study of C7-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of C7 pathway restoration in tumor cells with silenced or reduced C7 expression.
