Based on innovative and proprietary lipid-conjugation technology and formulation, this product exhibits significant difference from other siRNA transfection reagents in the market. Quick Protocol:Step 1: 1x105 cells are seeded in 24-well plate in 360 µl of appropriate growth medium containing serum and antibiotics on the day before transfection. Incubate the cells at 37 0C and 5 % CO2. The plate should be 60~70% confluent on the day of transfection. One hour before transfection, the serum-containing medium is replaced with 360 µl serum-free DMEM Medium with High Glucose. Step 2: For each well of 24-well plate, dilute 0.2 µg of siRNA in 40 µl of serum-free DMEM Medium with High Glucose. Vortex for 2 seconds and briefly spin down. Then dilute SuperFection™ Reagent 2.0 µl to 40 µl serum-free DMEM Medium with High Glucose. Vortex for 2 seconds and briefly spin down. Drop the diluted SuperFection™ reagent into diluted siRNA solution immediately. Important ! do not mix the solutions in the reverse order ! Step 3: Vortex the two solutions immediately and spin down briefly to bring drops to the bottom of the tube. Incubate for 10 minutes at room temperature. Important ! do not leave the mixture longer than 15 minutes ! Step 4: Add the mixture of SuperFection™/siRNA complex directly to the serum-free DMEM Medium with High Glucose. Incubate at 37 0C and 5% CO2 for 4 hours. Step 5: Replace the siRNA containing medium with fresh cell growth medium with 10 % FBS and incubate at 37 0C and 5 % CO2 for additional 24 hours or 48~72 hours as needed. Step 6: Most RNA interference can be detected within 24 hours following transfection. Note: 1. The above transfection protocol is for 24-well plate. Other dish types refer to Table 3. 2. The protocol is optimized for adherent cell lines tested. To achieve the highest efficiency for specific cell(s), more optimization may be necessary. 3. The major factors for transfection optimization include siRNA quantity and siRNA/SuperFection™ ratio.
