Design Notes

Practical Tips

  • Controls: Order matched pairs (e.g., 5‑mC / 5‑hmC / 5‑fC / 5‑caC) to build standard curves and antibody validation sets.
  • Strand context: Sequence context (CpG, CpH) can affect antibody and enzyme readouts; provide target locus if relevant.
  • RNA work: For m6A or 5‑mrC, consider 2′‑mods (2′‑OMe/2′‑F/MOE) when nuclease resistance is required.
  • QC & docs: Add optional endotoxin/residuals/stability when materials are used in vivo or for tech transfer.

Need a matched epigenetic standards set?

We’ll design a panel (5‑mC/5‑hmC/5‑fC/5‑caC, m6A/m6dA, etc.) with the right lengths, placements, and QC to fit your assay.

FAQ

Which formats do you support (DNA/RNA; single/duplex)?

ssDNA/dsDNA and ssRNA, plus siRNA duplexes on request. We’ll recommend placement (single site vs multi‑site) based on your assay.

Can you provide matched epigenetic control sets?

Yes—common kits include 5‑mC/5‑hmC/5‑fC/5‑caC ladders, m6A/m6dA pairs, and mixed panels for antibody or enzyme validation.

What QC do you recommend?

LC‑MS identity and HPLC/UPLC purity are standard. Optional tests include endotoxin, residual solvents/moisture, and time‑scheduled stability.

Can you help with assay design and packaging?

Absolutely—sequence design, control placement, formulation, and plate/vial packaging with labels/barcodes are all available.
