不对称二甲基精氨酸(ADMA)检测试剂盒Specificity

This assay has high sensitivity and excellent specificity for detection of Asymmetrical Dimethylarginine (ADMA).
No significant cross-reactivity or interference between Asymmetrical Dimethylarginine (ADMA) and analogues was observed.

Recovery

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

Matrix     Recovery range (%)     Average(%)    

serum(n=5)     78-92     87    

EDTA plasma(n=5)     92-101     96    

heparin plasma(n=5)     96-103     101    

Precision

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

不对称二甲基精氨酸(ADMA)检测试剂盒Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Asymmetrical Dimethylarginine (ADMA) 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)     87-101%     85-97%     98-105%     93-101%    

EDTA plasma(n=5)     86-96%     84-101%     91-98%     95-102%    

heparin plasma(n=5)     85-102%     98-105%     83-92%     90-101%    

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.

不对称二甲基精氨酸(ADMA)检测试剂盒Test principle

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Asymmetrical Dimethylarginine (ADMA) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Asymmetrical Dimethylarginine (ADMA) and unlabeled Asymmetrical Dimethylarginine (ADMA) (Standards or samples) with the pre-coated antibody specific to Asymmetrical Dimethylarginine (ADMA). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Asymmetrical Dimethylarginine (ADMA) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Asymmetrical Dimethylarginine (ADMA) in the sample.
