Human Anti-MBP(Anti-Myelin Basic Protein Antibody) ELISA Kit

Overview

Product name: Human Anti-MBP(Anti-Myelin Basic Protein Antibody) ELISA Kit
Reactivity: Human
Alternative Names: Myelin A1 protein; Myelin membrane encephalitogenic protein
Assay Type: Competitive Inhibition
Sensitivity: 1.28 ng/mL
Standard: 200 ng/mL
Detection Range: 3.13-200 ng/mL
Sample Type: Serum, plasma and other biological fluids
Assay Length: 2.5h
Research Area: Infection immunity;Neuro science;Autoimmunity;
Test principle: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human Anti-MBP protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human Anti-MBP. 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 Human Anti-MBP 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 Anti-MBP and the recovery rates were calculated by comparing the measured value to the expected amount of Anti-MBP in samples.
Matrix Recovery range Average
serum(n=5) 96-107% 102%
EDTA plasma(n=5) 85-99% 92%
Heparin plasma(n=5) 83-95% 89%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Anti-MBP 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) 81-94% 96-105% 92-103% 82-96%
EDTA plasma(n=5) 86-97% 83-96% 91-103% 96-105%
Heparin plasma(n=5) 88-103% 86-97% 87-102% 89-101%
