胃动素(MTL)检测试剂盒  的详细介绍

胃动素(MTL)检测试剂盒ELISA Kit for Motilin (MTL)
FOR IN VITRO AND RESEARCH USE ONLY, NOT FOR USE IN CLINICAL DIAGNOSTIC PROCEDURES!
Organism species Homo sapiens (Human)
Product No. YBA575Hu
Sample type Serum, plasma and other biological fluids
Format 96T
Assay length 2.5 hours
Detection range 74.07-6000pg/mL The standard curve concentrations used for the ELISA’s were 6000pg/mL, 2000pg/mL, 666.67pg/mL, 222.22pg/mL, 74.07pg/mL
Sensitivity The minimum detectable dose of this kit is typically less than 28.62pg/mL.
胃动素(MTL)检测试剂盒Specificity
This assay has high sensitivity and excellent specificity for detection of Motilin (MTL). 
No significant cross-reactivity or interference between Motilin (MTL) and analogues was observed.
Recovery
Matrices listed below were spiked with certain level of recombinant Motilin (MTL) and the recovery rates were calculated by comparing the measured value to the expected amount of Motilin (MTL) in samples. 
Matrix Recovery range (%) Average(%)
serum(n=5) 82-95 89
EDTA plasma(n=5) 87-94 90
heparin plasma(n=5) 83-95 88
胃动素(MTL)检测试剂盒Precision
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Motilin (MTL) were tested 20 times on one plate, respectively. 
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Motilin (MTL) were tested on 3 different plates, 8 replicates in each plate. 
CV(%) = SD/meanX100 
Intra-Assay: CV<10% 
Inter-Assay: CV<12% 
胃动素(MTL)检测试剂盒Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Motilin (MTL) 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) 84-101% 85-92% 85-95% 82-102%
EDTA plasma(n=5) 99-105% 81-93% 99-105% 98-105%
heparin plasma(n=5) 97-104% 81-96% 96-105% 80-101%
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.

胃动素(MTL)检测试剂盒Test principle
This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Motilin (MTL) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Motilin (MTL) and unlabeled Motilin (MTL) (Standards or samples) with the pre-coated antibody specific to Motilin (MTL). 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 Motilin (MTL) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Motilin (MTL) in the sample.
