IL-4 Kit ELISA

N° du produit ABIN955909

Détail du produit IL-4 Kit ELISA

Antigène: IL-4 (IL4) (Interleukin 4 (IL4))

Reactivité: Lapin

Méthode de détection: Colorimetric

Type de méthode: Sandwich ELISA

Gamme de detection: 15.6-1000 pg/mL

Seuil minimal de détection: 15.6 pg/mL

Application: ELISA

Fonction: The kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of rabbit IL4 in serum, plasma, tissue homogenates, cell culture supernates and other biological fluids.

Analytical Method: Quantitative

Specificité: This assay has high sensitivity and excellent specificity for detection of rabbit IL4. No significant cross- reactivity or interference between rabbit IL4 and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us - complete the cross-reactivity detection between rabbit IL4 and all the analogues, therefore, cross reaction may still exist.

Sensibilité: The minimum detectable dose of rabbit IL4 is typically less than 5.4 pg/mL.
The Sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined by adding two standard deviations - the mean optical density value of twenty zero calibrator replicates and calculating the corresponding concentration.

Attributs du produit: The microtiter plate provided in this kit has been pre-coated with an antibody specific to IL4. Calibrators or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific for IL4. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain IL4, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm +/- 10 nm. The concentration of IL4 in the samples is then determined by comparing the O.D. of the samples to the calibration curve.

Information d'application

Commentaires:

The calibration curve concentrations used for the ELISA's were 1000 pg/mL, 500 pg/mL, 250 pg/mL, 125 pg/mL, 62.5 pg/mL, 31.2 pg/mL, 15.6 pg/mL.

Plaque: Pre-coated

Calcul des résultats:

Average the duplicate readings for each calibrator, control, and samples and subtract the average zero calibrator optical density. Create a calibration curve on log-log graph paper, with IL4 concentration on the y-axis and absorbance on the x-axis. Draw the best fit straight line through the calibrator points and it can be determined by regression analysis. Using some plot software is also recommended. If samples have been diluted, the concentration read from the calibration curve must be multiplied by the dilution factor.

Restrictions: For Research Use only

Stockage

Stock: -20 °C

Stockage commentaire: All the reagents should be kept according to the labels on vials. The Calibrator, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20° C upon being received. The unused strips should be kept in a sealed bag with the desiccant provided to minimize exposure to damp air. Opened test kits will remain stable until the expiration date shown, provided it is stored as prescribed above.

Date de péremption: The expiry date is stated on the label.
