MIS CRISPR Activation Plasmid (h): sc-400715-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- MIS CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- MIS 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 MIS CRISPR Activation Plasmid (h) and MIS CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the AMH 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: MIS Antibody (B-11): sc-166752

Anti-Müllerian hormone (AMH), also known as Müllerian inhibiting substance (MIS), is a secreted TGF-β superfamily ligand that signals primarily through AMHR2 and type I receptors to activate SMAD1/5/8-dependent transcription. In human development, AMH/MIS is essential for male sexual differentiation by promoting regression of Müllerian ducts, and in the adult it contributes to gonadal cell communication and regulation of folliculogenesis. AMH expression is widely used as a marker of Sertoli and granulosa cell state, linking it to endocrine regulation and reproductive tissue biology. Dysregulated AMH/MIS signaling or expression has been associated with disorders of sex development, altered ovarian reserve phenotypes, and gonadal tumor biology, supporting mechanistic studies of developmental and reproductive pathways.
MIS CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous AMH expression without altering the underlying DNA sequence.
MIS CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the AMH 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 AMH transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous MIS expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native AMH locus and enabling the study of MIS-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of MIS pathway restoration in tumor cells with silenced or reduced AMH expression.
