Application Protocols

• Item-specific (from Product Data)
  • Tested applications and recommended conditions: Not specified for this item; refer to datasheet.
• General workflow for pLenti sgRNA use (not item-specific; example guidance only)
  1. Guide verification: sequence the sgRNA region to confirm spacer identity.
  2. Lentiviral packaging: co-transfect HEK293T with vector, packaging, and envelope plasmids using a lipid reagent in serum-free medium; swap to complete medium after 6–24 h.
  3. Harvest and clarify viral supernatant at 48–72 h; optionally concentrate (e.g., ultracentrifugation or PEG-based methods) following BSL-2 rules.
  4. Transduction: add viral supernatant to target cells, optionally with polybrene; incubate 12–24 h and replace medium.
  5. Selection: apply the appropriate antibiotic if the backbone encodes resistance (marker not specified for this item). Expand surviving cells.
  6. Assay editing: extract genomic DNA at 2–4 days; PCR-amplify RNF186 locus; analyze by T7E1, ICE/TIDE, or amplicon NGS. For CRISPRi/a, quantify RNF186 transcripts/protein by qPCR/Western.
  7. Clonal isolation (optional): dilute or sort single cells; expand and genotype.
• Notes
  • Optimize MOI, selection stringency, and assay timing per cell type. Follow institutional biosafety policies for viral work.

Biological Roles

• Item-specific (from Product Data)
  • Target specificity, organism, and guide sequence: Not specified for this item; refer to CoA/Spec Sheet.
• Literature/general context on RNF186 (not item-specific)
  • RNF186 encodes a RING-type E3 ubiquitin ligase reported to localize to endoplasmic reticulum membranes. E3 ligases confer substrate specificity in ubiquitin-mediated protein modification.
  • Putative roles include regulation of protein quality control and stress-responsive signaling via ubiquitination of specific substrates. Exact substrates and pathways can be cell-type dependent and remain under active study.
  • Genetic perturbation of RNF186 is used in research to dissect ER-associated degradation (ERAD) pathways, proteostasis, and downstream transcriptional programs.
• Reagent functional context (general)
  • An sgRNA directed to RNF186 enables targeted recruitment of Cas9/dCas9 systems to RNF186 coding or regulatory regions for knockout, repression, activation, or editing studies, facilitating genotype–phenotype analysis in cellular models.

Buffer Applications

• Not typically applicable
  • This product is a plasmid DNA construct and is not a buffering agent. It is commonly handled in nuclease-free water or TE buffer supplied by the manufacturer or prepared by the user.
• Practical note (general)
  • If reconstitution is required, use nuclease-free water or TE (10 mM Tris·HCl, 1 mM EDTA, pH 8.0). Exact buffer composition for this item is not specified.

Green Alternatives

• Context
  • This is a nucleic acid reagent; “green alternatives” relate to delivery methods and process choices rather than solvent substitution.
• Greener practice options (general, not item-specific)
  • Delivery approach: use non-viral delivery (electroporation or lipid nanoparticles) to avoid lentiviral packaging waste and BSL-2 requirements when feasible.
  • Media and plastics: minimize single-use plastics by consolidating preparations and using recyclable materials where permitted by biosafety rules.
  • Transfection reagents: choose less cytotoxic, biodegradable lipids or PEI alternatives when compatible with cell type and required efficiency.
  • Energy use: plan batch experiments to reduce freezer door openings and centrifuge runs; store working aliquots at −20 °C short term to limit −80 °C cycles if stability allows.
• Trade-offs
  • Non-viral methods may yield lower stable expression in difficult cell types; lentivirus provides high efficiency and long-term expression but requires additional containment and generates chemical/biological waste.
