Recovery of the High Sensitive ELISA Kit for Leucyl/Cystinyl Aminopeptidase (LNPEP)

Matrices listed below were spiked with certain level of recombinant High Sensitive Leucyl/Cystinyl Aminopeptidase (LNPEP) and the recovery rates were calculated by comparing the measured value to the expected amount of High Sensitive Leucyl/Cystinyl Aminopeptidase (LNPEP) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 91-99 96
EDTA plasma(n=5) 86-98 92
heparin plasma(n=5) 90-102 98

Precision of the High Sensitive ELISA Kit for Leucyl/Cystinyl Aminopeptidase (LNPEP)

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

Linearity of the High Sensitive ELISA Kit for Leucyl/Cystinyl Aminopeptidase (LNPEP)

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of High Sensitive Leucyl/Cystinyl Aminopeptidase (LNPEP) 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) 96-105% 86-103% 80-104% 82-94%
EDTA plasma(n=5) 82-95% 82-99% 79-91% 79-101%
heparin plasma(n=5) 80-94% 96-104% 79-93% 93-101%

Stability of the High Sensitive ELISA Kit for Leucyl/Cystinyl Aminopeptidase (LNPEP)

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.

Test principle of the High Sensitive ELISA Kit for Leucyl/Cystinyl Aminopeptidase (LNPEP)

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to High Sensitive Leucyl/Cystinyl Aminopeptidase (LNPEP). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to High Sensitive Leucyl/Cystinyl Aminopeptidase (LNPEP). 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 High Sensitive Leucyl/Cystinyl Aminopeptidase (LNPEP), 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 High Sensitive Leucyl/Cystinyl Aminopeptidase (LNPEP) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
