2.Features
INTENDED USE
The kit is a sandwich enzyme immunoassay for the in vitro quantitative measurement of BAI1 in human serum, plasma, tissue homogenates or other biological fluids.
 
DETECTION RANGE
0.156-10ng/mL. The standard curve concentrations used for the ELISA’s were 10ng/mL, 5ng/mL, 2.5ng/mL, 1.25ng/mL, 0.625ng/mL, 0.312ng/mL, 0.156ng/mL.
 
 SENSITIVITY
The minimum detectable dose of BAI1 is typically less than 0.065ng/mL.
The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined by adding two standard deviations to the mean optical density value of twenty zero standard replicates and calculating the corresponding concentration.
 
 SPECIFICITY
This assay has high sensitivity and excellent specificity for detection of BAI1.
No significant cross-reactivity or interference between BAI1 and analogues was observed.

Test principle

The microtiter plate provided in this kit has been pre-coated with an antibody specific to the index. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to the index. 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 the index, 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 the index in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Recovery

Matrices listed below were spiked with certain level of recombinant and the recovery rates were calculated by comparing the measured value to the expected amount of the index in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 81-93 86
EDTA plasma(n=5) 80-97 88
heparin plasma(n=5) 90-101 95

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample 1:2 1:4 1:8 1:16
serum(n=5) 82-96% 83-98% 81-99% 93-101%
EDTA plasma(n=5) 88-101% 86-95% 90-102% 80-93%
heparin plasma(n=5) 80-91% 82-90% 95-104% 79-95%

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

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.
