Produktdetails AQP2 ELISA Kit

Target: AQP2 (Aquaporin 2 (Collecting Duct) (AQP2))

Reaktivität: Maus

Nachweismethode: Colorimetric

Methodentyp: Competition ELISA

Applikation: ELISA

Verwendungszweck: This AQP-2 ELISA kit is intended for laboratory research use only and is not for use in diagnostic or therapeutic procedures.

Analytische Methode: Quantitative

Produktmerkmale: The coated well immunoenzymatic assay for the quantitative measurement of AQP-2 utilizes a polyclonal anti-AQP-2 antibody and an AQP-2-HRP conjugate. The assay sample and buffer are incubated together with AQP-2-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450 nm in a microplate reader. The intensity of the color is inversely proportional to the AQP-2 concentration since AQP-2 from samples and AQP-2-HRP conjugate compete for the anti-AQP-2 antibody binding site. Since the number of sites is limited, as more sites are occupied by AQP-2 from the sample, fewer sites are left to bind AQP-2-HRP conjugate. Calibrators of known AQP- 2 concentrations are run concurrently with the samples being assayed and a calibration curve is plotted relating the intensity of the color (Optical Density) to the concentration of AQP-2. The AQP-2 concentration in each sample is interpolated from this calibration curve.

Anwendungsinformationen

Plattentyp: Pre-coated

Aufbereitung der Reagenzien:

Bring all kit components and samples to room temperature (18-25°C) before use. Dispense 10 µL of lysis buffer solution into 100 µL specimens, mix and stand for one hour (The proportion of lysis buffer and specimens should be no less than 1:10). (NOTE: This step is required when the sample is cell culture fluid & body fluid & tissue homogenate, If the sample is serum or blood plasma, then this step should be skipped.) Wash Solution Dilute 10 mL of Wash Solution concentrate (100X) with 990 mL of de-ionized or distilled water to prepare 1,000 mL of Wash Solution (1X).

Testdurchführung:

It is recommended that all Calibrators and Samples be added in duplicate to the Microtiter Plate.
1. Secure the desired number of coated wells in the holder, then add 100 µL of Calibrators or Samples to the appropriate well of the antibody pre-coated Microtiter Plate.
2. Add 50 µL of Conjugate to each well. Mix well. Mixing well in this step is important. Cover and incubate the plate for 1 hour at 37°C.
3. Wash the microtiter plate using one of the specified methods indicated below:
4. Manual Washing: Remove incubation mixture by aspirating contents of the plate into a sink or proper waste container. Fill in each well completely with diluted wash solution, and then aspirate contents of the plate into a sink or proper waste container. Repeat this procedure five times for a total of five washes. After washing, invert plate, and blot dry by hitting plate onto absorbent paper or paper towels until no moisture appears. Note: Hold the sides of the plate frame firmly when washing the plate to assure that all strips remain securely in frame. Complete removal of liquid at each step is essential to good performance.
5. Automated Washing: Wash plate five times with diluted wash solution (350-400 µL/well/wash) using an auto washer. After washing, dry the plate as above. It is recommended that the washer be set for a soaking time of 10 seconds and shaking time of 5 seconds between each wash.
6. Add 50 µL substrate A and 50 µL substrate B to each well, subsequently. Cover and incubate for 15 minutes at 20-25°C. (Avoid sunlight.)
7. Add 50 µL stop solution to each well. Mix well.
8. Read the optical density (OD) at 450 nm using a microtiter plate reader immediately.

Ergebnisberechnung:

1. This calibration curve is used to determine the amount of an unknown sample. Construct a calibration curve by plotting the average OD (450 nm) for each calibrator on the vertical (Y) axis against the concentration on the horizontal (X) axis, and draw a best fit curve through the points on the graph.
   2. First, calculate the mean OD value for each calibrator and sample. All OD values are subtracted by the mean value of the blank control before result interpretation. Construct the calibration curve using graph paper or statistical software.
   3. To determine the amount in each sample, first locate the OD value on the Y-axis and extend a horizontal line to the calibration curve. At the point of intersection, draw a vertical line to the X-axis and read the corresponding concentration.
   4. Any variation in operator, pipetting and washing technique, incubation time or temperature, and kit age can cause variation in the result. Each user should obtain their own calibration curve.
   5. The sensitivity in this assay is 0.1 ng/mL.
   6. This assay has high sensitivity and excellent specificity for detection of AQP-2. No significant cross- reactivity or interference between AQP-2 and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between AQP-2 and all the analogues, therefore, cross reaction may still exist in some cases.
