Linearity: The linearity of the kit was assayed by testing serially diluted matrices spiked with a fixed amount of recombinant GPT1. The results were demonstrated by the percentage of calculated concentration related to the expected concentration of GPT1 in the diluted matrices.

Calibratrion curve:

AEE0009 to GPT1 was successfully used to determine the concentration of GPT1 in serum, plasma and buffer. Recommended serum dilution 1:16, and EDTA plasma dilution 1:8.

Calibration curve of recombinant GPT1 in buffer. HRP detection by Absorbance at 450nm.

Selectivity of the ELISA kit:

AEE0009 to GPT1 was successfully confirmed selective as there were no signals found in the presence of other closely related proteins at high and low concentrations.

Selectivity was tested by comparing the signals of recombinant GPT1 with other closely related recombinant proteins, each at two concentrations. The other related proteins tested were GPT2, and GOT1. HRP detection by Absorbance at 450nm.

ELISA Test:

The microtiter plate provided in this kit has been pre-coated with an antibody specific to GPT1. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to GPT1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain GPT1, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of GPT1 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

ELISA Procedure:

1. Prepare all reagents, samples and standards;
2. Add 100µL standard or sample to each well. Incubate 2 hours at 37℃;
3. Aspirate and add 100µL prepared Detection Reagent A. Incubate 1 hour at 37℃;
4. Aspirate and wash 3 times;
5. Add 100µL prepared Detection Reagent B. Incubate 1 hour at 37℃;
6. Aspirate and wash 5 times;
7. Add 90µL Substrate Solution. Incubate 15-25 minutes at 37℃;
8. Add 50µL Stop Solution. Read at 450nm immediately.

Stability:

The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions.
Note:
To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
