- 原理
- The Rat Beta 2-Microglobulin ELISA is a highly sensitive two-site enzyme-linked immunoassay (ELISA) for the quantitative determination of Beta 2-Microglobulin in rat biological fluids.

- 产品特性
- In this assay the B2M present in the sample reacts with the anti-B2M antibody which has been adsorbed to the surface of polystyrene microtiter wells. After the removal of unbound sample proteins by washing, anti-B2M antibody conjugated with horseradish peroxidase (HRP) is added. This HRP-conjugated antibody forms a complex with the previously bound B2M. 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 is proportional to the concentration of B2M in the sample tested, thus, the absorbance, at 450 nm, is a measure of the concentration of B2M in the test sample. The quantity of B2M 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 with desiccant and re-seal.
7. Rat B2M Calibrator: The Rat B2M Calibrator should be aliquoted and stored frozen. It is at a concentration of 1.60 µg/mL and needs to be diluted in 1X diluent according to the chart below for each run. Rat B2M calibrators need to be prepared immediately prior to use. Mix well between each step. Avoid foaming.
8. Positive Control: The concentration and recommended dilution are provided on the Control Certificate. Before use, briefly centrifuge the Positive Control to allow all of the liquid to collect in the bottom of the vial.
- Diluent Concentrate: The Diluent solution supplied is a 5X concentrate and must be diluted 1:5 with distilled or de-ionized water.

- 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. A second order polynomial (quadratic) or other curve fits may also be used.
3. Interpolate test sample values from the calibration curve. Correct for sample dilution factor to arrive at B2M 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.

- 背景
- Beta 2-Microglobulin (B2M) is an 11 kDA protein. It forms the subunit of the MHC class I molecule and associates with the outer membrane of many cells including lymphocytes. It is present in low levels in serum and urine of normal people, but at a higher concentration in people with renal diseases, kidney transplants and various other inflammatory and infectious conditions.
