ALCAM CRISPR Activation Plasmid (m): sc-419076-ACT
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- ALCAM CRISPR Activation Plasmid (m) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- ALCAM 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 ALCAM CRISPR Activation Plasmid (m) and ALCAM CRISPR Activation Plasmid (m2) target distinct regulatory regions upstream of the Alcam 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: ALCAM Antibody (B-6): sc-74558

Alcam encodes activated leukocyte cell adhesion molecule (ALCAM/CD166), an immunoglobulin superfamily receptor that mediates homophilic and heterophilic interactions to regulate cell–cell adhesion, migration, and tissue organization in mouse development and adult homeostasis. ALCAM participates in processes linked to cytoskeletal remodeling and junctional dynamics, influencing epithelial integrity, neuronal pathfinding, and immune cell trafficking. Through its adhesion-dependent signaling, ALCAM can modulate pathways controlling proliferation and differentiation, including context-dependent effects on MAPK and PI3K-AKT signaling output. Dysregulated ALCAM expression has been associated with altered stem-like properties, invasion, and metastatic behavior across multiple disease models, making it a useful node for studying adhesion-driven phenotypic plasticity.
ALCAM CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Alcam expression without altering the underlying DNA sequence.
ALCAM CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Alcam 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 Alcam transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous ALCAM expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Alcam locus and enabling the study of ALCAM-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of ALCAM pathway restoration in tumor cells with silenced or reduced Alcam expression.
