If there is precipitation in the rinsing solution when stored at 2-8 ℃, please restore it to room temperature, dissolve the precipitation, and use it normally. The 1x rinsing solution can be stored at room temperature for one month.4. It is recommended to stain the membrane with reagents such as spring red after the transfer is completed, and cut off any excess parts on the membrane to increase the efficiency of the reagents.5. The optimal dilution amount for primary antibody and antibody reaction solution HRP (rabbit) needs to be determined through preliminary experiments.6. Antibody reaction solution HRP (rabbit), antibody dilution solution, and antibody dosage can be increased or decreased proportionally according to the size of the membrane.7. The antibody dilution solution containing the first antibody can be recycled and reused once. Antibodies with low specificity and affinity are not recommended for repeated use. If the recovered antibody is used within 1-2 days and stored at 2-8 ℃ for long-term storage, please freeze it at -20 ℃ to avoid repeated freeze-thaw cycles.8. If there is a high background, please adjust the amount of antibodies and increase the number of times the film is washed.9. All reagents in the reagent kit should be stored at 2-8 ℃ to avoid freezing and thawing.Operation steps:This product is suitable for the sealing and antibody incubation steps after membrane transfer, taking a 5 cm x 8 cm membrane as an example:1. Preparation of rinsing solution: Dilute 10 ml of Wash Buffer (10 x) with distilled water to 100 ml, which is 1 x Wash Buffer. Set aside. Use 8-10 ml for each film wash.2. Sealing: After the membrane transfer is completed, immerse the membrane in 10 ml Blocking Buffer and seal at room temperature for 5 minutes.3. Rinse: Pour off the sealing solution, add 8-10 ml of 1 x Wash Buffer, and rinse at a high speed on a shaker for 1 minute.4. Prepare antibody incubation solution while washing the membrane: Take Antibody Pretreat Solution (HRP/Rabbit) 100 µ Add rabbit derived primary antibody 3-10 into the centrifuge tube µ g. Suck and beat the gun head until thoroughly mixed, and incubate at room temperature for 5 minutes. Add to 10 ml Dilution Buffer and mix well. Note: 1) The dosage of primary antibody can also be adjusted according to the dilution of the antibody.
