Recommended Sample Dilution Ratio The following table shows the recommended dilution ratios for this kit for a limited number of samples for your reference only. (The matrix components in serum/plasma will affect the test results, which it need to be diluted at least 1/2 with Sample Dilution Buffer before testing! When the content of other samples is very low, the original solution can be added without dilution, but it is necessary to ensure that the pH is between 6.8 and 8.0, and it does not contain more than 10 % organic solvents or high-concentration protein denaturants.) 1. Common sample validation: Sample Type Recommended Dilution Ratio Content Healthy serum (n=19) 1/2 dilution ND-16pg/mL Healthy plasma (EDTA, Citrate , heparin) (n=20) 1/2 dilution ND-14pg/mL Human peripheral blood cells were cultured in RPMI 1640 supplemented with 10 %FBS, 100 units/mL penicillin, and 100 μg/mL streptomycin sulfate, followed by stimulated with 10 μg/mL PHA for 24 hours. The cell culture supernatants were assayed for levels of human IL-2. undiluted 612pg/mL Wild-type Jurkat cells were cultured in DMEM supplemented with 10 %FBS, 100 units/mL penicillin, and 100 μg/mL streptomycin sulfate for 12 hours. The cell culture supernatants were assayed for levels of human IL-2. 1/2 dilution ND Wild-type Jurkat cells were cultured in DMEMsupplemented with 10 %FBS, 100 units/mL penicillin, and 100 μg/mL streptomycin sulfate, followed by stimulated with 10 μg/mL LPS for 12 hours. The cell culture supernatants were assayed for levels of human IL-2. 1/2 dilution 697pg/mL 2. KD sample validation (Detect IL-2-KD Jurkat cells): Sample Type Dilution Ratio Content Wild-type Jurkat cells were cultured in DMEM supplemented with 10 %FBS, 100 units/mL penicillin, and 100 μg/mL streptomycin sulfate for 12 hours. The cell culture supernatants were assayed for levels of human IL-2. 1/2 dilution 624pg/mL Jurkat cells (+siRNA) were cultured in DMEM supplemented with 10 %FBS, 100 units/mL penicillin, and 100 μg/mL streptomycin sulfate for 12 hours. The cell culture supernatants were assayed for levels of human IL-2. 1/2 dilution 58pg/mL Note:ND is lower than the sensitivity of the kit and was not detected 3. Verified recombinant protein: (It is a normal phenomenon that some proteins have weak detection signals or cannot be detected at all due to differences in tags, sequences or protein activities) A. HEK293-derived Human IL-2 protein Met1-Thr153B. E. coli-derived Human IL-2 protein Ala21-Thr153

Commentaires:

Sandwich ELISA, Double Antibody

Volume d'échantillon: 100 μL

Durée du test: 4 h

Plaque: Pre-coated

Protocole: Step 1: Add 100 µL standard or sample into each well, seal the plate and statically incubate for 90 minutes at 37 °C. Washing: Wash the plate twice without immersing. Step 2: Add 100 µL biotin-antibody working solution, seal the plate and statically incubate for 60 minutes at 37 °C. Washing: Wash the plate three times and immerse for 1 min each time. Step 3: Add 100 µL HRP-Streptavidin Conjugate (SABC) working solution, seal the plate and statically incubate for 30 minutes at 37 °C. Washing: Wash the plate five times and immerse for 1 min each time. Step 4: Add 90 µL TMB substrate solution, seal the plate and statically incubate for 10-20 minutes at 37 °C. (Accurate TMB visualization control is required.) Step 5: Add 50 µL stop solution. Read at 450nm immediately and calculate.
