Sp2 CRISPR Activation Plasmid (h): sc-405026-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Sp2 CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- Sp2 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 Sp2 CRISPR Activation Plasmid (h) and Sp2 CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the SP2 transcriptional start site. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Sp2 Antibody (A-8): sc-17814

Human SP2 encodes Sp2, a ubiquitously expressed Sp/KLF family transcription factor that binds GC-rich promoter elements to regulate basal transcription of genes involved in cell cycle progression, chromatin organization, and metabolic homeostasis. Sp2 activity interfaces with RNA polymerase II–dependent transcriptional control and can influence gene regulatory networks governed by promoter architecture and epigenetic state. Dysregulated Sp-family transcriptional programs have been linked to altered proliferation and stress-response signaling, supporting investigation of SP2 in contexts such as oncogenic transcriptional rewiring and lineage-specific differentiation defects. As a nuclear DNA-binding regulator, Sp2 is commonly studied for its role in promoter occupancy, transcription factor crosstalk, and downstream pathway modulation.
Sp2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous SP2 expression without altering the underlying DNA sequence.
Sp2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the SP2 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 SP2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Sp2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native SP2 locus and enabling the study of Sp2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Sp2 pathway restoration in tumor cells with silenced or reduced SP2 expression.
