FAPα CRISPR Activation Plasmid (m): sc-420286-ACT
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- FAPα CRISPR Activation Plasmid (m) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- FAPα CRISPR Activation Plasmid (m) 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 FAPα CRISPR Activation Plasmid (m) and FAPα CRISPR Activation Plasmid (m2) target distinct regulatory regions upstream of the Fap transcriptional start site. One or both designs may be available

Mouse Fap encodes fibroblast activation protein alpha (FAPα), a cell-surface serine protease enriched in activated fibroblasts and stromal cell populations that remodel extracellular matrix. FAPα participates in pericellular proteolysis and matrix turnover, shaping tissue repair, fibrosis-associated remodeling, and stromal–immune interactions within inflammatory microenvironments. Dysregulated Fap expression is frequently used as a marker of activated fibroblast states and has been linked to fibroblast-driven changes that influence tumor-associated stroma, wound healing dynamics, and chronic inflammatory pathology.
FAPα CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Fap expression without altering the underlying DNA sequence.
FAPα CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Fap 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 Fap transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous FAPα expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Fap locus and enabling the study of FAPα-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of FAPα pathway restoration in tumor cells with silenced or reduced Fap expression.
