Stabillity at RT
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

Test Principle
This assay employs the competitive inhibition enzyme immunoassay technique. An antibody specific to a1AT has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled a1AT and unlabeled a1AT (Standards or samp
Precision
CV(%) = SD/meanX100
Inter-Assay: CV<12%
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Alpha-1-Antitrypsin (a1AT) were tested on 3 different plates, 8 replicates in each plate.
Intra-Assay: CV<10%
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Alpha-1-Antitrypsin (a1AT) were tested 20 times on one plate, respectively.
