Recovery

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

Matrix Recovery range (%) Average(%)
serum(n=5) 80-95 84
EDTA plasma(n=5) 92-101 96
heparin plasma(n=5) 90-98 94

Precision

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

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Albumin (ALB) 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) 84-96% 92-104% 85-102% 92-99%
EDTA plasma(n=5) 82-105% 97-105% 94-102% 97-105%
heparin plasma(n=5) 90-99% 92-101% 86-96% 83-94%

Stability

The stability of 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 condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

ELISA Kit for Albumin (ALB)

Test principle

The microtiter plate provided in this kit has been pre-coated with an antigen. Standards or samples are then added to the appropriate microtiter plate wells with a Horseradish Peroxidase (HRP)-conjugated secondary antibody. After TMB substrate solution is added, those wells that contain Albumin (ALB) 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 Albumin (ALB) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
