IL-1 beta ELISA Kit

Catalog No. ABIN955896

Product Details IL-1 beta ELISA Kit

Target: IL-1 beta (IL1B) (Interleukin 1, beta (IL1B))

Reactivity: Rat

Detection Method: Colorimetric

Method Type: Sandwich ELISA

Detection Range: 15.6-1000 pg/mL

Minimum Detection Limit: 15.6 pg/mL

Application: ELISA

Purpose: This ELISA kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of rat IL1B in serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids.

Analytical Method: Quantitative

Specificity: This assay has high sensitivity and excellent specificity for detection of rat IL1B. No significant cross- reactivity or interference was observed.

Sensitivity: The minimum detectable dose of rat IL1 B is typically less than 4.2 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 the mean O.D. value of 20 replicates of the zero calibrator plus three standard deviations.

Characteristics: The microtiter plate provided in this kit has been pre-coated with an antibody specific to IL1B. Calibrators and samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for IL1B. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the TMB substrate solution is added to each well. Only those wells that contain IL1B, 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 +/- 2 nm. The concentration of IL1B in the samples is then determined by comparing the O.D. of the samples to the calibration curve.

Application Details

Comment:

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

Plate: Pre-coated

Calculation of Results:

Average the duplicate readings for each calibrator, control, and sample and subtract the average zero calibrator optical density. Create a calibration curve by reducing the data using computer software capable of generating a four parameter logistic (4-PL) curve-fit. As an alternative, construct a calibration curve by plotting the mean absorbance for each calibrator on the x-axis against the concentration on the y-axis and draw a best fit curve through the points on the graph. The data may be linearized by plotting the log of the IL1B concentrations versus the log of the O.D. and the best fit line can be determined by regression analysis. This procedure will produce an adequate but less precise fit of the data. It is recommended to use some related software to do this calculation. If samples have been diluted, the concentration read from the calibration curve must be multiplied by the dilution factor.

Restrictions: For Research Use only

Handling

Storage: -20 °C

Storage Comment: 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.

Expiry Date: The expiry date is stated on the label.
