ZY FectEasy RNA Transfection Reagent

Efficient delivery of siRNA, miRNA, and saRNA

ZY FectEasy RNA Transfection Reagent uses an optimized cationic liposome formula to achieve efficient delivery of small RNAs.


In common cells such as HeLa, MCF7, and NIH-3T3, low concentrations of siRNA can achieve more than 90% gene silencing efficiency; for difficult-to-transfect suspension cells such as K562 and THP-1, transfection efficiency over 80% can also be observed.

Procedure for Adherent Cells

Using a 24-well plate and 10 nM siRNA as an example
  • Seeding and dilution
    The day before transfection, the confluency should be 30%–50%. Take 0.25 μL of 20 μM siRNA and add it to 100 μL of serum-free medium or Opti-MEM, mix gently.
  • Add reagent and incubate
    Add 0.75 μL of reagent, vortex for 10 s; incubate at room temperature for 10 min, not exceeding 30 min.
  • Change medium and transfection
    Change to 0.4 mL of pre-warmed complete medium; add 100 μL of the complex, gently swirl in a straight line, final volume 500 μL, siRNA final concentration 10 nM.
  • Detection
    Detect interference effect by qPCR or Western Blot after 24–72 h.

Procedure for Suspension Cells

Change medium and transfection
  • Seeding and dilution
    Change to 0.4 mL of pre-warmed complete medium; add 100 μL of the complex, gently swirl in a straight line, final volume 500 μL, siRNA final concentration 10 nM.
  • Add reagent and incubate
    Detection
  • Detect interference effect by qPCR or Western Blot after 24–72 h. ...
    Add 100 μL of the complex to 150 μL of serum-containing cell suspension, with a final volume of 250 μL and an siRNA final concentration of 100 nM; after 6 hours, add 250 μL of complete culture medium.
  • Detection and Tips
    Detect after 24–72 hours. A concentration of 20–100 nM is recommended, and increase the reagent dosage as appropriate; for sensitive cells, change the medium 4–6 hours after transfection.

Common Questions FAQ

RNA Transfection Optimization and Detection Q&A
What should I do if the transfection efficiency is low?
You can increase the concentration of siRNA and reagent; check different time points from 24–96 h; ensure 30%–50% confluence without RNase; use siRNA purified by PAGE and desalted, and confirm the double-stranded concentration and annealing conditions.
What should I do if there is high cytotoxicity?
Reduce the reagent volume, shorten the co-incubation time of the complex with the cells, replace the medium 4–6 hours after transfection, and verify whether target gene silencing affects cell viability.
