PRDM6 CRISPR/Cas9 KO Plasmid (h): sc-406414

Overview

PRDM6 encodes a PR/SET domain zinc finger protein that functions as a transcriptional regulator in vascular smooth muscle cells, helping maintain a contractile phenotype by modulating gene programs linked to proliferation and differentiation. It interacts with chromatin to influence epigenetic states and downstream transcriptional networks, including pathways governing smooth muscle maturation and vessel wall remodeling. Altered PRDM6 activity has been implicated in congenital and acquired vascular pathologies, where dysregulated smooth muscle gene expression contributes to aberrant vascular development and function. As a nuclear regulator of lineage-specific transcription, PRDM6 is commonly studied in the context of cardiovascular biology, developmental gene control, and epigenetic mechanisms.

PRDM6 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the PRDM6 gene in human cell lines. Each plasmid in the pool co-expresses a unique sgRNA, targeting a distinct site within the PRDM6 locus, alongside the Streptococcus pyogenes Cas9 nuclease, and encodes GFP to enable fluorescent identification and enrichment of successfully transfected cells. This multi-guide strategy increases the likelihood of inducing frameshifts or deletions that produce a functional knockout, offering a more robust alternative to single-guide approaches. DSBs induced at multiple sites are resolved through non-homologous end joining (NHEJ) or, when used with the included HDR donor template, homology-directed repair (HDR) at a defined target site within the locus.

When used in conjunction with the RFP-expressing HDR donor, GFP and RFP fluorescence can be used together to distinguish transfected from edited cell populations, streamlining flow cytometry-based sorting and clone selection workflows.

Homology-Directed Repair (HDR) Donor — Puromycin Cassette with RFP Reporter

For applications requiring confirmed, selectable knockout clones, PRDM6 HDR Plasmid (h) includes an HDR donor construct containing a puromycin resistance cassette (PuroR) and a red fluorescent protein (RFP) reporter, flanked by homology arms specific to a defined PRDM6 target site.
When co-transfected with PRDM6 CRISPR/Cas9 KO Plasmid (h):

• The PuroR-RFP cassette integrates at the Cas9 cut site via HDR, disrupting the PRDM6 open reading frame.
• RFP fluorescence provides an immediate visual indicator of successful integration, enabling fluorescence-based identification or sorting of edited cells prior to or alongside puromycin selection.
• Successfully edited cells are confirmed through puromycin resistance, substantially reducing clone screening burden.
• This selection strategy is ideal for generating stable, clonal KO cell lines for downstream functional studies, drug screening, or model development.

Cre-lox Cassette Removal System

The HDR donor construct features loxP sites flanking the PuroR-RFP selection cassette to allow clean marker removal following clone confirmation. Transient expression of Cre recombinase via the included Cre Vector: sc-418923 excises the cassette, leaving a minimal residual loxP site within the PRDM6 locus and eliminating potential confounding effects on downstream assays.
This two-step approach:

• Minimizes disruption to local chromatin architecture and neighboring regulatory elements
• Restores a near-native genomic context at the edited locus
• Enables reuse of the puromycin selection strategy in the same cell line for additional edits
