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 Normal mouse serum (n=16) undiluted ND-20pg/mL Normal mouse plasma (EDTA, Citrate , heparin) (n=16) undiluted ND-30pg/mL RAW 264.7 cells were cultured with 5 %FBS + 1640 + double antibody for 12 hours undiluted 32pg/mL RAW 264.7 cells were cultured with 5 %FBS+ 1640 + double antibody +1 μg/mL LPS, and the cell culture supernatant was detected after 12 hours undiluted or 1/2 dilution 705pg/mL RAW 264.7 cells were cultured with 5 %FBS+ 1640 + double antibody +1 μg/mL LPS for 12 hours. After that, 300 ng/mL Brefeldin A (BFA) was added and cultured for 3 hours. Add cell lysis buffer(Catalogue No.:E050), collect the lysate solution (total protein concentration measured by BCA assay: 2.39 mg/mL) to detect. 1/10 dilution 1.16 ng/mg(total protein) 2. KD sample validation (Detect TNF-α-KD RAW 264.7 cells): Sample Type Dilution Ratio Content Wild RAW 264.7 cells were stimulated with 1 μg/mL LPS for 12 hours to detect cell culture supernatant 1/5 dilution 695pg/mL RAW 264.7 cells (+siRNA) were stimulated with 1 μg/mL LPS for 12 hours to detect cell culture supernatants undiluted ND RAW 264.7 cells (+siRNA) were treated with 1 μg/mL LPS for 12 hours and then cultured with 300 ng/mL Brefeldin A (BFA) for 3 hours. Add cell lysis buffer(Catalogue No.:E050), collect the lysate solution (total protein concentration measured by BCA assay: 1.75 mg/mL) to detect. undiluted 21pg/mg(total protein) Note:ND is lower than the sensitivity of the kit and was not detected 3. Antibody by WB KD validation (Detect TNF-α-KO RAW 264.7 cells):

Sensibilité: 2.344 pg/mL

Commentaires:

Sandwich ELISA, Double Antibody

Volume d'échantillon: 50 μL

Durée du test: 2 h

Plaque: Pre-coated

Protocole: 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.

Procédure de l'essai:

1. Take out the required strips, add 50 µL Cap/Det Ab into each well, then add 50 µL Standard or Sample into relevant 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 complete mixing then statically incubate for 60 minutes at 37 °C.
2. Wash the plate twice without immersion.
3. Add 100 µL HRP-Streptavidin (orange) into each well, seal the plate and statically incubate for 30 minutes at 37 °C.
