Pig ADM(Adrenomedullin) ELISA Kit

Overview

Product name: Pig ADM(Adrenomedullin) ELISA Kit
Reactivity: Pig
Alternative Names: AM; PAMP; Proadrenomedullin N-20 terminal peptide; ProAM N-terminal 20 peptide
Assay Type: Competitive Inhibition
Sensitivity: 4.85 pg/mL
Standard: 1000 pg/mL
Detection Range: 15.63-1000 pg/mL
Sample Type: Serum, plasma and other biological fluids.
Assay Length: 2h
Research Area: Endocrinology;Hormone metabolism;
Test principle: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Pig ADM protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Pig ADM. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. 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 Pig ADM in the samples is then determined by comparing the OD of the samples to the standard curve.

Precision

Intra-assay Precision (Precision within an assay)：CV%<8%

Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-assay Precision (Precision between assays)：CV%<10%

Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.

Recovery

Matrices listed below were spiked with certain level of recombinant ADM and the recovery rates were calculated by comparing the measured value to the expected amount of ADM in samples.
Matrix Recovery range Average
serum(n=5) 95-108% 101%
EDTA plasma(n=5) 80-95% 87%
Heparin plasma(n=5) 82-97% 91%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of ADM and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
Matrix 1:2 1:4 1:8 1:16
serum(n=5) 95-102% 97-105% 87-103% 90-99%
EDTA plasma(n=5) 88-97% 96-105% 91-103% 89-97%
Heparin plasma(n=5) 82-94% 92-104% 82-96% 95-102%
