特异性
- Cross-reactivity with turkey IgA has not been investigated. Normal turkey IgG levels are in the range of 4-9 mg/mL in serum or plasma and ~5 mg/mL in egg yolk.

产品特性
- The turkey IgG ELISA kit is intended for measurement of IgG in serum, plasma and egg-yolk extracts. Goat anti-turkey IgG (H+L) antibodies are used for solid phase (microtiter wells) immobilization and horseradish peroxidase (HRP) conjugated goat anti-turkey IgG (Fc specific) antibodies are used for detection.Test samples are diluted and incubated in the microtiter wells for 45 minutes alongside prepared turkey IgG calibrators. The microtiter wells are subsequently washed and HRP conjugate is added and incubated for 45 minutes. IgG molecules are thus sandwiched between the immobilization and detection antibodies. The wells are then washed to remove unbound HRP-labeled antibodies and TMB Reagent is added and incubated for 20 minutes at room temperature. This results in the development of a blue color. Color development is stopped by the addition of Stop Solution, changing the color to yellow, and optical density is measured spectrophotometrically at 450 nm. The concentration of IgG is proportional to the optical density of the test sample and is derived from a calibration curve.

General Note: IgG is typically present in turkey serum at concentrations of ~5 mg/mL. In order to obtain values within range of the calibration curve, we suggest that samples initially be diluted 200,000 fold using the following procedure for each sample to be tested:
1. Dispense 998 µL and 798 µL of 1X diluent into separate tubes.
2. Pipette and mix 2 µL of the serum/plasma sample into the tube containing 998 µL of diluent. This provides a 500 fold diluted sample.
3. Mix 2 µL of the 500 fold diluted sample with the 798 µL of diluent in the second tube. This provides a 200,000 fold dilution of the sample.
4. Repeat this procedure for each sample to be tested. -
实验流程
-
- Secure the desired number of coated wells in the holder.
2. Dispense 100 µL of calibrators and diluted samples into the wells (we recommend that samples be tested in duplicate).
3. Incubate on an orbital micro-plate shaker at 100-150 rpm at room temperature (18-25°C) for 45 minutes.
4. Aspirate the contents of the microtiter wells and wash the wells 5 times with 1x wash solution using a plate washer (400 µL/well). The entire wash procedure should be performed as quickly as possible.
5. Strike the wells sharply onto absorbent paper or paper towels to remove all residual wash buffer.
6. Add 100 µL of enzyme conjugate reagent into each well.
7. Incubate on an orbital micro-plate shaker at 100-150 rpm at room temperature (18-25°C) for 45 minutes.
8. Wash as detailed in 4 to 5 above.
9. Dispense 100 µL of TMB Reagent into each well.
10. Gently mix on an orbital micro-plate shaker at 100-150 rpm at room temperature (18-25°C) for 20 minutes.
11. Stop the reaction by adding 100 µL of Stop Solution to each well.
12. Gently mix. It is important to make sure that all the blue color changes to yellow.
13. Read the optical density at 450 nm with a microtiter plate reader within 5 minutes.
- Secure the desired number of coated wells in the holder.

结果分析
-
- Calculate the average absorbance values (A450) for each set of reference calibrators and samples.
2. Construct a calibration curve by plotting the mean absorbance obtained from each reference calibrator against its concentration in ng/mL on linear graph paper, with absorbance values on the vertical or Y-axis and concentrations on the horizontal or X-axis.
3. Using the mean absorbance value for each sample, determine the corresponding concentration of IgG in ng/mL from the calibration curve.
4. Multiply the derived concentrations by the dilution factor to determine the actual concentration of IgG in the sample.
5. PC graphing software may be used for the above steps.
6. If the OD450 values of the sample fall outside the calibration curve, samples should be diluted appropriately and re-tested.
