COL15A1 CRISPR Activation Plasmid (h) | sc-404027-ACT | 20 µg | $397.00 |
COL15A1 encodes collagen type XV alpha 1 chain, a non-fibrillar basement membrane–associated collagen that contributes to extracellular matrix organization and tissue structural integrity. It influences cell–matrix adhesion, migration, and mechanotransduction by shaping the perivascular and interstitial microenvironment and modulating integrin- and focal adhesion–linked signaling. COL15A1 expression is associated with vascular homeostasis and stromal remodeling, making it relevant to studies of angiogenesis, fibrosis, and tumor microenvironment regulation. Dysregulated COL15A1 has been reported across multiple pathological contexts where basement membrane composition and matrix remodeling are altered.
COL15A1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous COL15A1 expression without altering the underlying DNA sequence.
COL15A1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the COL15A1 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 COL15A1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous COL15A1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native COL15A1 locus and enabling the study of COL15A1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of COL15A1 pathway restoration in tumor cells with silenced or reduced COL15A1 expression.
