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. (When the sample content 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=21) undiluted ND-536pg/mL Healthy plasma (EDTA, Citrate , heparin) (n=22) undiluted ND-517pg/mL Human peripheral blood mononuclear cells (2 x 10^6 cells/mL) were cultured in RPMI 1640 supplemented with 10 %FBS, 100 units/mL penicillin for 48 hours. The cell culture supernatants were assayed for levels of human IL-21. undiluted ND Human peripheral blood mononuclear cells (2 x 10^6 cells/mL) 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 48 hours. The cell culture supernatants were assayed for levels of human IL-21. undiluted 403pg/mL 2. KD sample validation (Detect IL-21-KD PBMC cells): Sample Type Dilution Ratio Content Wild Human peripheral blood mononuclear cells (2 x 10^6 cells/mL) 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 48 hours. The cell culture supernatants were assayed for levels of human IL-21. undiluted 446pg/mL Human peripheral blood mononuclear cells (+siRNA) 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 48 hours. The cell culture supernatants were assayed for levels of human IL-21. undiluted 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. E. coli-derived Human IL-21 protein Gln30-Ser162

Sandwich ELISA, Double Antibody

Probenmenge: 50 μL

Testdauer: 2 h

Plattentyp: Pre-coated

Protokoll: Step 1: Take out the required plate wells, add 50 µL Cap/Det Ab into each well, then add 50 µL Standard or Sample into individual well. (When adding standard or sample, the disposable tip lightly touches the liquid level. Change the disposable tips for different samples and standards.) Gently tap the plate for 10s to ensure thorough mixing then static incubate for 60 minutes at 37 °C. Washing: Wash the plate twice without immersion. Step 2: Add 100 µL HRP-Streptavidin (orange) into each well, seal the plate and static incubate for 30 minutes at 37 °C. Washing: Wash the plate five times without immersion. Step 3: Add 90 µL TMB substrate solution, seal the plate and static incubate for 10-20 minutes at 37 °C. (Accurate TMB visualization control is required.) Step 4: Add 50 µL stop solution. Read at 450nm immediately and calculate.
