- 原理
- The Human Retinol Binding Protein ELISA is a highly sensitive two-site enzyme-linked immunoassay (ELISA) for the quantitative determination of Retinol Binding Protein in human biological samples.
- Analytical Method
- Quantitative
- 产品特性
- In this assay the Retinol Binding Protein (RBP) present in samples reacts with the anti-Retinol Binding Protein antibodies which have been adsorbed to the surface of polystyrene microtiter wells. After the removal of unbound proteins by washing, anti-Retinol Binding Protein antibodies conjugated with horseradish peroxidase (HRP), are added. These enzyme-labeled antibodies form complexes with the previously bound Retinol Binding Protein. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3',5,5'-tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of Retinol Binding Protein in the sample tested, thus, the absorbance, at 450 nm, is a measure of the concentration of Retinol Binding Protein in the test sample. The quantity of Retinol Binding Protein in the test sample can be interpolated from the calibration curve constructed from the calibrators, and corrected for sample dilution.

- Diluent Concentrate: The Diluent solution supplied is a 5X concentrate and must be diluted 1:5 with distilled or de-ionized water.
2. Wash Solution Concentrate: The Wash Solution supplied is a 20X concentrate and must be diluted 1:20 with distilled or de-ionized water. Crystal formation in the concentrate is not uncommon when storage temperatures are low. Warming of the concentrate to 30-35°C before dilution can dissolve crystals.
3. Enzyme-Antibody Conjugate Concentrate: Calculate the required amount of working conjugate solution for each microtiter plate test strip by adding 10 µL Enzyme-Antibody Conjugate to 990 µL of 1X Diluent for each test strip to be used for testing. Mix uniformly, but gently. Avoid foaming.
4. TMB Substrate Solution: Ready to use as supplied.
5. Stop Solution: Ready to use as supplied.
6. Microtiter Plate: Ready to use as supplied. Unseal microtiter pouch and remove plate from pouch. Remove all strips and wells that will not be used in the assay and place back in pouch and re-seal along with desiccant.
7. Human Retinol Binding Protein Calibrator: Add 1.0 mL of distilled or de-ionized water to the lyophilized Human Retinol Binding Protein Calibrator and mix gently until dissolved. The calibrator is now at a concentration of 4.25 µg/mL (the reconstituted calibrator should be aliquoted and frozen if future use is intended). Prepare the Human Retinol Binding Protein Calibrators immediately prior to use according to the table below. Mix well between each step. Avoid foaming.
- Diluent Concentrate: The Diluent solution supplied is a 5X concentrate and must be diluted 1:5 with distilled or de-ionized water.
- 结果分析
-
- Subtract the average background value from the test values for each sample.
2. Using the results observed for the calibrators construct a calibration curve. The appropriate curve fit is that of a four- parameter logistics curve, although a second order polynomial (quadratic) or other curve fits may also be used.
3. Interpolate test sample values from calibration curve. Correct for sample dilution factor to arrive at Retinol Binding Protein concentration in original sample.
1. Reliable and reproducible results will be obtained when the assay procedure is carried out with a complete understanding of the information contained in the package insert instructions and with adherence to good laboratory practice.
2. Factors that might affect the performance of the assay include proper instrument function, cleanliness of glassware, quality of distilled or de-ionized water, and accuracy of reagent and sample pipettings, washing technique, incubation time or temperature.
- Subtract the average background value from the test values for each sample.
